APR Low Pressure Fueling System for the EA113 and EA888 2.0T!

Posted on April 16, 2014 – 9:00 am

Achtuning is pleased to present the release of APR’s ultimate low pressure fueling system upgrade for the VAG EA113 and EA888 2.0T engines!

The APR Low Pressure Fuel Pump (LPFP) Upgrade is designed to ensure the low pressure fueling system is capable of delivering the proper volume of fuel from the fuel tank to the high pressure fueling system under high demand situations.

Key Components and Benefits:

  • APR LPFP ECU, harness & bracket
  • APR 255 LPH high pressure inline fuel pump & bracket
  • OEM quality fuel lines, crimp clamps & quick connectors
  • Clean and simple solution to OEM low pressure fueling system
  • Allows for higher output calibrations with select APR Stage 3/3+ Turbocharger Systems.
  • Integrated into factory CAN bus
  • Quiet and cool low power operation, only on when needed
  • Quick fuel tank empting mode for use with switching fuel grades or dry storage/transportation
  • No unintended side effects common with other parts
  • No ECU software required
  • Only needed where specified by APR

OEM Fueling System Overview:

The OEM fueling system consists of several key components:

  • Direct injection injectors
  • Direct injection high-pressure fuel pump (HPFP)
  • In tank PWM-controlled low-pressure fuel pump (LPFP)
  • LPFP controller
  • Engine control unit (ECU)

The high-pressure fuel pump (HPFP) needs to provide the injectors with a large volume of fuel to satisfy the desired air to fuel ratio. The injectors are only able to spray for a very small window of time, so the HPFP must provide the fuel at high pressures, upwards of 200 bar. In some instances, if the injectors are a limiting factor, they can be enlarged to reduce the time they need to spray. In other instances, the bore and or stroke of the HPFP can be increased to increase the volume of fuel displaced by the HPFP. By increasing the volume of fuel between the HPFP and the injectors, pressure behind the injectors increases and the amount of time the injectors need to spray decreases.

Unfortunately under some situations, the HPFP is cable of displacing a larger volume of fuel than it receives from the low pressure fueling system. As demand goes up, the low pressure fueling system needs to work harder to provide the volume of fuel necessary, but in some situations, the factory unit is unable to do so.

The APR LPFP increases the supply of fuel from the fuel tank to the HPFP to ensure the HPFP displaces the maximum volume of fuel possible during each stroke. This ensures the HPFP is capable of working at 100% capacity.

Challenges to upgrading the LPFP:

  • Very little room for upgraded pump
  • OEM Pump requires a PWM signal
  • OEM pump controller overheats with high output pumps
  • Upgraded OEM pump controller not fully compatible
  • ECU modifications may be required
  • Secondary controllers often rely on physical boost signals

The factory LPFP sits in a basket submerged in the vehicle’s gas tank. The pump operates off of a pulse-width modulated (PWM) signal sent from the pump’s control module, which is mapped in the ECU. As fueling demand increases and decrease, the PWM signal adjusts to send only the required amount of fuel through the pump.

Unfortunately upgrading the LPFP is not a simple drop in task. The pump’s factory enclosure presents some packaging constraints limiting clean expansion to a larger unit. Likewise, doing so often results in overheating and subsequent protective shut down of the factory control unit as it’s operating outside of its intended design. This is even true when installing larger and expensive factory units like those found on high output vehicles, such as the Audi TT RS and RS3. Furthermore, upgrading the LPFP control module with the matching expensive higher output control units present other issues as the controller receives CAN messages from integrated vehicle componentry not common on vehicles requiring an upgraded LPFP.

The APR Solution:

  • Inline fuel pump
  • Fuel pump controller with proper ECU CAN bus communication
  • Clean mounting brackets included
  • Direct bolt on with no software required

APR took a multi-step approach to solving the low pressure fueling system and is pleased to present a clean and accurately controlled solution for high horsepower applications.

The APR LPFP System features a 255 LPH high-pressure inline fuel pump that sits between the HPFP and the factory LPFP. The included APR Auxiliary ECU sits on the factory CAN bus and receives critical operating information from the factory ECU to accurately control the pump. As fueling demands increase and decrease, the APR Auxiliary ECU controls output of the pump to deliver the desired volume of fuel to the HPFP.

By connecting to the factory CAN bus, the APR Auxiliary ECU eliminate the need for less sophisticated and often problematic methods of controlling the upgraded pump. Because the pump only runs when needed, less power is consumed, fuel temperature is lower and noise, especially at idle, is essentially non-existent.

Finally, with the fuel line disconnected, with the click of a buttion the APR Auxiliary ECU allows the user to quickly and easily empty the vehicle’s fuel tank to make way for switching to higher octane fuels or for dry storage and transportation.

APR’s new 1.8/2.0 TSI EA888 Gen 3 Intercooler System!

Posted on April 15, 2014 – 9:55 am

Achtuning is pleased to present the release of APR’s ultimate Front Mount Intercooler System for the transverse 1.8T and 2.0T direct injected engines!

The APR Intercooler System dramatically lowers charge air temperature and resists heat soak far better the factory intercooler system. Through a massively increased core volume, superior intercooler core design and smooth, cast end tanks, APR’s engineers were able to create an intercooler capable of supporting power levels well beyond that of the factory unit. Expect increased horsepower and torque and dramatically prolonged performance.

  • Dramatically lowers intake air temperature
  • Increases horsepower and torque while prolonging performance
  • APR intercooler core dimensions: 2.25″ x 16.25″ x 22″
  • 40% larger than stock
  • Larger inlets and outlets
  • Pressure tested for leak proof operation
  • Smooth cast aluminum end tanks
  • Barbed hose connection points for a slip proof fit
  • Machined mounting points for extra weight savings
  • CNC machined billet adapter
  • Multi Ply Silicon Hoses with APR’s EZ-Flow stepped design
  • Direct OEM fitment with no trimming necessary
  • Full install directions and APR’s world-renowned customer support
  • Lifetime warranty

Intercooler Ambient Air Fins

Each unit uses a high quality, bar and plate core with staggered and louvered fins. The Intercooler’s exceptionally tall design and fin structure exposes the core to a greater volume of airflow than possible with the factory or similar aftermarket short and thick core designs. With more of the intercooler directly exposed to the elements, cooling effectiveness dramatically increases.

Intercooler Charge Air Fins

Internally, the APR Intercooler System features a staggered and louvered fin design with a core density chosen as a balance between cooling effectiveness and pressure drop. Due to the core’s massive volume, the balance was easily adjusted to favor minimal pressure drop while still providing superior effectiveness compared to the stock tube and fine design.

APR Easy-Flow Silicone Hoses

Multi-ply silicone hoses provide an unrestricted path for airflow entering and exiting the intercooler. The hoses are engineered to properly connect the intercooler to the factory charge piping system.

APR’s Easy-Flow Silicone Hose design features stepped mounting surfaces for smooth transitions from one pipe to another. Traditional designs simply sit on top of each other, often resulting in a disruptive airflow path. By using the stepped design, hoses fit properly without airflow restrictions, resulting in the most ideal path for moving air through the intercooler and into the engine.

Testing Data

Several tests were done in order to prove the differences between the stock intercooler and the APR one. One test for thermal effectiveness involved placing the car on the dyno with our normal assortment and arrangement of cooling fans. The car was then run through a rigorous testing procedure that involved allowing it to idle to a normal operating temperature, and then running it through five power runs.

During each run, the engine speed was brought to 2000 rpm for fifteen seconds. This allows the air to run throughout the system and allows the intake air temperature to normalize and negate heat soak from the car sitting at idle. The car was then taken from 2000rpm to 6800rpm at full throttle under load over the next thirty seconds. The car was then allowed to idle for one minute before the next run was started. Each lighter line on the graph above represents each power run, and the darker line represents the average over five runs.

The stock intercooler was tested on one day, the APR intercooler was installed, and the testing repeated the next day. The conditions were very similar on both days, but it was slightly hotter (3ºF) on the day the APR intercooler was tested.

Most alarming about this entire test was the fact that during the third run with the stock intercooler, the car began to pull boost and timing in order to protect itself from the high intake temperatures. The car also exhibited this protective behavior in both the fourth and fifth runs as well.

The APR intercooler performed as we expected, keeping the intake charge temps almost 40ºF lower by the end of the fifth run.

APR K04 Turbo

Posted on April 9, 2014 – 9:00 am

APR’s Engineering Teams have finished final testing of new “version 3.0″ K04 Turbocharger software for the 2.0 TSI/TFSI EA888 Gen 1 engine.  The new ECU Upgrade improves upon power deliver on top of what was previously a tremendous upgrade over stock!  Amidst addressing all previous concerns, additional motorsport features were added to further enhance your driving experience. Updates are now available here at Achtuning and is offered as a FREE software update for APR K04 Turbo Upgrade customers!

  • Please call to check file availability before booking an appointment! 
  • An OEM Bosch 3-Bar Map sensor is REQUIRED to run this software. 

Presenting the APR 2.0 TSI EA888 Gen 1 K04 Turbocharger System!

For the budget minded individual, APR is pleased to offer software and hardware utilizing an APR proprietary customized version of the factory Borg Warner K04-64 turbocharger. Originally equipped on VAG’s high output models, such as the Golf R and S3, the APR K04 Turbocharger System offers a substantial leap in power and torque all with excellent response in a reliable and stealthy, compact design. Expect lightning fast response, smooth daily driving and power that transform the vehicle into a new class of enjoyment.

The APR K04 Turbocharger System features many upgrades over the 2.0T’s factory equipped IHI turbocharger, making it an excellent upgrade. The integrated turbofold design features a cast stainless steel exhaust manifold and turbine housing, integrated into one single unit. This design aids in turbocharger spool while the stainless steel construction is capable of withstanding higher exhaust gas temperature for longer periods of time than lesser materials, such as cast iron. The CNC-machined, billet aluminum compressor wheel and higher flow exhaust turbine wheel expand the turbo’s efficiency range, allowing for higher output across a wider RPM range.

True to APR’s mantra of Performance without Compromise the days of shredding tires on front wheel drive vehicles are rapidly disappearing thanks to the new Gold Standard in ECU torque management calibration strategies only APR can deliver. Compressor surge is avoided to increase the reliability of the system without limiting the area under the curve typically experienced during a top speed acceleration run. APR’s endless pursuit of perfection has resulted in the most comprehensive 2.0 TSI K04 turbocharger system and tuning package in the world.

Using 93-octane fuel, the APR K04 Turbocharger System produces an astonishing 360 horsepower and 382 ft-lbs of torque. Unlike the factory turbocharger, power stays strong and doesn’t dramatically taper towards the vehicle’s new 7,100 RPM redline. Switching to APR’s 100 octane race fuel mode, peak power and torque climb further to 375 horsepower and 408 ft-lbs of torque. APR’s calibration experts have safely maximized the full power potential of the turbocharger unit, while keeping reliability at the forefront of their calibration strategies.

APR K04 Turbocharger System Components

Turbocharger

 

At the heart of the K04 Turbocharger System is an APR proprietary customized version of the factory Borg Warner K04-64 turbocharger originally equipped on VAG’s high-output models, such as the Golf R and S3. The turbocharger features a CNC-machined, billet compressor wheel and stainless steel exhaust turbofold.

Each turbocharger unit is machined, assembled and clocked in house at APR with the necessary brackets to ensure proper wastegate fitment and orientation. Each wastegate is then calibrated for precise operation and control to ensure seamless integration with the expertly recalibrated OEM engine management system.

Integrated DV Adapter

One of the greatest benefits to the APR K04 turbocharger system is its simple, yet elegant design. APR’s CNC-machined direct compressor recirculation port on the OEM compressor cover significantly reduces engine bay clutter and saves the end user from the hidden costs of purchasing extra throttle body pipes, hoses, clamps and DV mounts for recirculating boost pressure. The compact design also removes extra charge piping volume to allow for faster boost response and less locations for boost leaks. Furthermore, charge air pressure is directed directly at the compressor wheel which helps keep the turbo spooled upon lifting the throttle, minimizing turbo lag.

Turbo Outlet and Turbo Muffler Removal

The OEM k04 turbocharger features a turbo muffler designed to reduce turbocharger sound, but does so at the cost of ultimate performance. APR removes the turbo muffler not only to enhance the sound of the turbocharger, but to also provide a smooth airflow path across the previously baffled muffler section. A clean and simple CNC flange developed by APR’s Mechanical Engineers is bolted directly to the compressor cover in place of the OEM turbo muffler. A long mounting surface provides an excellent slip-proof surface for mounting the included APR EZ-Flow silicone discharge hose and an o-ring between the flanges ensures a life of leak-proof operation.

PCV Blockoff Plate

The K04 turbocharger was originally designed for an EA113 2.0T engine, and as such, includes items not present on the EA888 2.0T engine. The compressor cover features a port used in the EA113’s PCV system, but on the EA888’s this same port is located higher up on the intake tubing. APR has provided a gasket-sealed laser-cut port cover to block off this part to ensure no unmetered air enters into the system. The design is clean and simple and never requires maintenance.

Engine Management

The factory Bosch MED 17 engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.

With the significant amount of changes included in the APR K04 Turbocharger System, APR’s Engineers spent months calibrating the engine management system, including hundreds of hours of in-house chassis dyno development. Drivability, gear changes, cruising and part throttle operation were tuned to operate smoothly as if intended by the OEM through proper torque management. Further development was performed putting the vehicle through performance evaluation and durability testing at the drag strip and road course. APR’s Electrical Engineers built new coding functions, strategies and routines into the ECU to control conditions normally unseen at factory power levels. Thanks to APR’s incredible proprietary calibration suite, data logging software and full access to the coding structure of the ECU, appropriate and intelligent changes are made to ensure flawless drivability and excellent performance without compromise.

Engine Calibration:

APR’s Calibration Engineers restructured the engine’s volumetric efficiency (VE) model to correctly determine the ECU’s calculated load and deliver proper torque management. Thanks to APR’s patented boost control coding and the addition of a 3-Bar MAP sensor, the ECU is able to perform closed loop boost control well beyond relatively low limits dictated by the factory MAP sensor. This directly translates to safer and more predictable operation while additionally producing more power and torque across the entire power band.

Additionally, through the properly reconstructed VE model, accurate open loop fueling is achieved, translating to insignificant fuel trim adjustments. Closed loop fueling is calibrated to control lambda perfectly under all operating conditions. Furthermore, compensations, such as ones related to intake air temperature, exhaust temperature, and altitude, are adjusted to handle the larger variances compared to the factory, low-output setup.

APR’s Calibration Engineers have optimized cam timing, ignition timing, engine load and lambda to provide tremendous leaps in power while retaining the OEM knock control strategy. The result is safely achieved power, optimized for various fuel grades found around the world from low-quality pump fuel, all the way to high-quality, oxygenated race fuels.

Compressor Surge Avoidance:

To aid in turbocharger reliability and longevity, APR’s engineers carefully studied the turbocharger’s compressor maps to avoid regions where compressor surge may be experienced. The K04 turbocharger has fantastic response characteristics and is able to produce incredibly high pressure at low airflow levels, but in doing so, the turbocharger runs into issues of compressor surge. In the area between 3000-4000 RPM, APR’s Calibration Experts have elected to limit boost pressure. During testing, with the limits removed, APR’s engineers were able to easily achieve over 400 ft-lbs of torque with 93 octane fuel, but doing so could result in damaging the turbo’s reliability. Back-to-back testing was conducted with and without the limitation and despite the reduction in torque in this range, APR’s engineers were unable to record a measureable difference in accelerative performance.

Torque Management and Traction Control:

Torque management plays a big role in how the vehicle feels and performs, especially during moments of low gear, rapid acceleration. Typically front wheel drive vehicles suffer from excessive wheel spin during these moments due to the massive torque on tap from the K04 Turbocharger System. Some drivers can find themselves in situations where they are fighting against wheel spin and traction control when they are simply interested in going forward as quickly as possible. This is further compounded by the fact that the factory traction control (ASR) system was designed for vehicles producing far less power and torque, resulting in overcompensated ASR interventions.

APR’s Calibration Engineers set out to perfect torque management and traction control by minimizing wheel spin as much as possible without neutering the driving experience. A multi-step approach was taken to achieve appropriate control. With ASR enabled, forward movement wheel spin will trigger appropriate torque intervention levels to minimize spin without hurting forward acceleration. On top of this, the torque management system is fine tuned to deliver only as much torque as the tires can take. In normal conditions the tires will only slightly break loose under full acceleration, resulting maximum acceleration. In higher traction situations, or with ASR disabled, all of the system’s torque is directly on tap!

While the end goal is similar, APR’s torque management system differs greatly from archaic “boost-by-gear” strategies. “Boost-by-gear” strategies rely on a static limitation of boost in an effort to minimize wheel spin, but to work properly they must be dialed in for every situation. The same boost levels in different weather conditions, such as a hot summer day and a cold winter month, can produce vastly different torque levels. Since APR’s torque management system relies on the engine management’s phenomenal torque reporting abilities, it is able to adjust to every environmental situation it encounters. To achieve a targeted torque level, the ECU applies the appropriate changes to mass airflow and ignition.

Acceleration Enhancements:

Through further calibration changes APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle. Ignition delays are reduced resulting in a more responsive pedal without altering overall throttle sensitivity and resolution. Drivability was greatly improved by reducing the throttle lag commonly noticed at slow speeds and while reapplying throttle after decelerating. APR’s Motorsport Rev Limiter allows power to climb all the way to redline without dropping off several hundreds of RPM earlier. Lastly, APR’s tried and tested Motorsport Launch Limiter allows the driver to focus on launching the vehicle, rather than controlling the engine speed.

Part-Throttle Drivability:

Beyond wide-open throttle performance, APR’s Calibration Engineers spent countless hours optimizing vehicle drivability under daily, part-throttle, driving. The vehicle fully retains its impressive daily driver status and simply has more power on tap should the driver request more with his or her right foot!

APR EMCS and APR Mobile:

APR’s EMCS program-switching technology and APR Mobile put control of the ECU in the operator’s hand to access modes for standard pump fuel, high-output race fuel and even reduced-output valet modes to protect the vehicle against improper use by other individuals. This technology is patented by APR and is found nowhere else in the world. It’s Performance Without Compromise only APR can deliver!

Manifold Absolute Pressure Sensor

To provide closed-loop boost control at absolute pressure levels above 2.5 bar, APR’s K04 Turbocharger System features an OEM Bosch 3 bar MAP sensor.

Altering the ECU to understand the engine is equipped with a 3 bar MAP sensor is a trivial task. The sensor and proper calibration settings come standard on many factory VAG vehicles, but even these vehicles only provide proper closed loop boost control up to 2.5 bar absolute.

APR’s electrical engineers went many steps beyond the norm and recoded the factory ECU to deliver closed-loop boost control up to 3-bar absolute. This ability, combined with proper torque management, results in safe, reliable, and predictable performance at higher power levels without the need for clumsy and archaic external boost controlling devices.

Silicone Hose


A wire-reinforced, multi-ply silicone hose provide an unrestricted path for airflow exiting the turbocharger. The hose is engineered to properly connect the turbo’s outlet to the factory charge piping system.

APR’s Easy-Flow Silicone Hose design features stepped mounting surfaces for smooth transitions from one pipe to another. Traditional designs simply sit on top of each other, often resulting in a disruptive airflow path. By using the stepped design, hoses fit properly without airflow restrictions, resulting in the most ideal path for moving air through the turbocharger and into the engine.

Gaskets and Hardware

APR doesn’t cut corners even with the most mundane details of the kit. Every nut, bolt, stud, washer, clamp, and gasket necessary for the install is included with the kit.

Dyno Testing

Horsepower and torque were measured in APR’s in-house, Soundmaster dyno cell, using a Dynapack all-wheel dynamometer. Multiple stock and modified runs were conducted and the SAEJ1349 corrected results were averaged together to represent the differences between a stock and APR K04 2.0 TSI. Crank power figures were estimated based on VAG’s factory advertised results.

Requirements and Recommendations

Intake System
APR’s software is designed to utilize the factory mass airflow (MAF) sensor and housing. The Carbonio Stage I and II Intake System is highly recommended and required to meet the advertised power output.

Exhaust System
The APR Downpipe Exhaust System is required if the vehicle is not currently equipped with the APR Turboback Exhaust System. APR Recommends the APR Catback Exhaust System for maximum performance.

Intercooler System
The APR Intercooler System is required to meet the advertised power figures.

Transmission
The K04 Turbocharger System greatly increases torque over the factory output levels and as such, an upgraded clutch may be necessary to transmit power to the ground. APR highly recommends upgrading the factory clutch to one that suits the operator’s intended driving style.

Exhaust Valve Springs
APR has discovered some engines experience exhaust valve float at high RPM at the advertised horsepower levels due to excessive exhaust backpressure caused by K04’s relatively small turbine wheel. In such cases, APR recommends upgrading the factory valve springs. However, upon request, lower output software capable of producing 321 horsepower and 310 ft-lbs of torque on 93 octane is available.

Tires
APR recommends Michelin PSS and PS2 tires as well as BFGoodrich Rivals and GForce Sport Comp 2 tires.

Fluids
APR recommends Motul Fluids and Lubricants.

APR: 2.0 TSI “Stage 3″ GTX Turbocharger Kit Released!

Posted on April 7, 2014 – 12:31 pm

Achtuning is excited to announce APR’s release of the 2.0 TSI EA888 Gen 1 Stage III GTX Turbocharger System!

In 2008, shortly after the worldwide release of the 2.0 TSI engine, Volkswagen of America commissioned APR to build the Stage III GT Turbocharger System for their SEMA concept cars. Successes of these concept cars lead to the first release of the APR Stage III Turbocharger System, based on the then available Garret GT turbocharger, and became a worldwide phenomenon. In the years since, APR has continued to work with VWoA, Volkswagen GmBH, VWVortex and BFGoodrich to deliver more concept cars for SEMA, Wörthersee in Austria, as well as other events around the world, while APR continued testing the latest in turbocharger technology.

With the introduction of the Garret GTX2867R Turbocharger, APR has raised the bar further and redefined the standard by which the VAG community measures performance, reliability, drivability and quality. Gone are the days of compromise where low-end response meant excessive backpressure, compressor surge, and extremely limited top end performance. True to APR’s mantra of Performance without Compromise the days of shredding tires on front wheel drive vehicles are rapidly disappearing thanks to the new Gold Standard in ECU torque management calibration strategies only APR can deliver. APR’s endless pursuit of perfection has resulted in the most comprehensive 2.0 TSI turbocharger system in the world.

The 2.0 TSI is completely transformed the second it meets an APR Stage III GTX Turbocharger System. Power immediately jumps to 423 horsepower with 387 ft-lbs of torque on tap using 93 octane fuel on a completely stock and unmodified factory fueling system. Switching to APR’s 100 octane race fuel mode, power shoots up to 458 horsepower with 409 ft-lbs of torque all at the driver’s command. This level of extreme performance is just a taste of the system’s full performance capabilities. APR’s Stage III+ GTX fueling system (Coming Soon!) increases performance further by simply adding a few bolt-on APR fueling components.

APR Commissioned Stage III Vehicles

APR Stage III GTX Turbocharger System Components

Turbocharger

At the heart of Stage III GTX Turbocharger System is a GTX2867R turbocharger, which is capable of flowing nearly 50 lbs/min of corrected air flow. This directly translates to large power gains on the 2.0 TSI that continue to grow all the way to redline. The GTX Turbocharger consists of the latest technologies from Le Mans’ winning turbo manufacturer, Garrett Honeywell, and has a track record of reliability and repeatability worthy of complementing an APR Turbocharger System.

The internally gated turbocharger features a fully-machined, ten-blade billet 49.7 mm compressor wheel, Inconel 53.9 mm turbine wheel and a dual ball bearing oil and water-cooled CHRA.

APR’s Engineers spent countless hours testing turbine inlet and A/R sizes in order to decrease turbocharger lag without negatively impacting peak power. Complementing the turbo’s lightning fast response characteristics is a newly developed anti-surge housing, which enables APR’s Calibration Engineers to deliver massive low-end torque without experiencing compressor surge.

Each turbocharger unit is assembled and clocked in house at APR with the necessary brackets to ensure proper wastegate fitment and orientation. Each wastegate is then calibrated for precise operation and control to ensure seamless integration with the expertly recalibrated OEM engine management system.

Engine Management

The factory Bosch MED 17 engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.

With the significant amount of changes included in the APR Stage III GTX Turbocharger System, APR’s Engineers spent months calibrating the engine management system, including hundreds of hours of in-house chassis dyno development. Drivability, gear changes, cruising and part throttle operation were tuned to operate smoothly as if intended by the OEM through proper torque management. Further development was performed putting the vehicle through performance evaluation and durability testing at the drag strip and road course. APR’s Electrical Engineers built new coding functions, strategies and routines into the ECU to control conditions normally unseen at factory power levels. Thanks to APR’s incredible proprietary calibration suite, data logging software and full access to the coding structure of the ECU, appropriate and intelligent changes are made to ensure flawless drivability and excellent performance without compromise.

Engine Calibration:

APR’s Calibration Engineers properly restructured the engine’s volumetric efficiency (VE) model to properly determine the ECU’s calculated load and deliver proper torque management. Thanks to APR’s patented boost control coding and the addition of a 3-Bar MAP sensor, the ECU is able to perform closed loop boost control well beyond relatively low limits dictated by the factory MAP sensor. This directly translates to safer and more predictable operation while additionally producing more power and torque across the entire power band.

Additionally, through the properly reconstructed VE model, accurate open loop fueling is achieved, translating to insignificant fuel trim adjustments. Closed loop fueling is calibrated to control lambda perfectly under all operating conditions. Furthermore, compensations, such as ones related to intake air temperature, exhaust temperature, and altitude, are adjusted to handle the larger variances compared to the factory, low output setup.

APR’s Calibration Engineers have optimized cam timing, ignition timing, engine load and lambda to provide tremendous leaps in power while retaining the OEM knock control strategy. The result is safely achieved power, optimized for various fuel grades found around the world from low quality pump fuel, all the way to high quality, oxygenated race fuels.

Torque Management and Traction Control:

Torque management plays a big role in how the vehicle feels and performs, especially during moments of low gear, rapid acceleration. Typically front wheel drive vehicles suffer from excessive wheel spin during these moments due to the massive torque on tap from the Stage III GTX Turbocharger System. Some drivers can find themselves in situations where they are fighting against wheel spin and traction control when they are simply interested in going forward as quickly as possible. This is further compounded by the fact the factory traction control (ASR) system was designed for vehicles producing far less power and torque, resulting in overcompensated ASR interventions.

APR’s Calibration Engineers set out to perfect torque management and traction control by minimizing wheel spin as much as possible without neutering the driving experience. A multi step approach was taken to achieve appropriate control. With ASR enabled, forward movement wheel spin will trigger appropriate torque intervention levels to minimize spin without hurting forward acceleration. On top of this, the torque management system is fine tuned to deliver only as much torque as the tires can take. In normal conditions the tires will only slightly break loose under full acceleration, resulting maximum acceleration. In higher traction situations, or with ASR disabled, all of the system’s torque is directly on tap!

While the end goal is similar, APR’s torque management system differs greatly from archaic “boost-by-gear” strategies. “Boost-by-gear” strategies rely on a static limitation of boost in an effort to minimize wheel spin, but to work properly they must be dialed in for every situation. The same boost levels in different weather conditions, such as a hot summer day and a cold winter month, can produce vastly different torque levels. Since APR’s torque management system relies on the engine management’s phenomenal torque reporting abilities, it is able to adjust to every environmental situation it encounters. To achieve a targeted torque level, the ECU applies the appropriate changes to mass airflow and ignition.

Acceleration Enhancements:

Through further calibration changes APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle. Ignition delays are reduced resulting in a more responsive pedal without altering overall throttle sensitivity and resolution. Drivability was greatly improved by reducing the throttle lag commonly noticed at slow speeds and while reapplying throttle after decelerating. APR’s Motorsport Rev Limiter allows power to climb all the way to redline without dropping off several hundreds of RPM earlier. Lastly, APR’s tried and tested Motorsport Launch Limiter allows the driver to focus on launching the vehicle, rather than controlling the engine speed.

Part Throttle Drivability:

Beyond wide open throttle performance, APR’s Calibration Engineers spent countless hours optimizing vehicle drivability under daily, part-throttle, driving. The vehicle fully retains its impressive daily driver status and simply has more power on tap should the driver request more with his or her right foot!

APR EMCS and APR Mobile:

APR’s EMCS program switching technology and APR Mobile put control of the ECU in the operators hand to access modes for standard pump fuel, high output race fuel and even reduced output valet modes to protect the vehicle against improper use by other individuals. This technology is patented by APR and is found nowhere else in the world. It’s Performance Without Compromise only APR can deliver!

Turbocharger Manifold

Attached to the turbocharger is APR’s investment-cast, super alloy, nickel-chromium-based Inconel 625 Manifold featuring APR’s Sequential Exhaust Pulse runner lengths. Unlike hand welded tubular manifolds and other cheap cast materials such as iron, Inconel is a very high temperature resistant material designed to withstand extreme exhaust gas temperature changes without expanding, contracting, melting or cracking under stress. Furthermore, the thick casting material reduces unwanted exhaust noise. This material is typically found only at the highest levels of professional motorsport racing where reliability is essential to success.

Investment-cast Inconel features heat retention characteristics, which aid in turbo response by keeping the exhaust velocity high. APR’s Engineers designed variable runner lengths calibrated to deliver sequential exhaust pulses without collision. Along with the manifold’s T25 outlet, this aids in turbocharger spool, producing excellent response for immediate torque delivery. A reduction in backpressure from the high-flow, collision-free design directly enhances power delivery far beyond that of the OEM turbocharger manifold and other less effective designs. Backpressure reduction also alleviates most common valve float issues associated with high output factory s3gtx turbo upgrades and so called small “hybrid” s3gtx turbochargers.

Each unit undergoes strict quality control checkpoints to ensure ultimate reliability each step of the manufacturing process. The unit is CNC machined to tight tolerances and inspected for defects before being packaged and shipped to customers around the world.

All of these characteristics result in a manifold designed without compromise backed by a confidence-inspiring lifetime warranty.

Manifold Absolute Pressure Sensor

To provide closed loop boost control at absolute pressure levels above 2.5 bar, APR’s GTX Turbocharger System features an OEM Bosch 3 bar MAP sensor.

Altering the ECU to understand the engine is equipped with a 3 bar MAP sensor is a trivial task. The sensor and proper calibration settings come standard on many factory VAG vehicles, but even these vehicles only provide proper closed loop boost control up to 2.5 bar absolute.

APR’s electrical engineers went many steps beyond the norm and recoded the factory ECU to deliver closed loop boost control up to 3 bar absolute. This ability, combined with proper torque management, results in safe, reliable, and predictable performance at higher power levels without the need for clumsy and archaic external boost controlling devices.

Mass Air Flow Sensor Housing

The factory engine management relies on load calculations derived from the mass airflow (MAF) sensor to properly control the engine. All too often this critical component is eliminated from turbo upgrade kits as the factory unit is small and can easily become saturated. The alternative of upgrading the unit is often not used due to the complexity of doing so. However, no task is too large for APR’s Engineering Teams when the sake of reliability is brought into question, and as such APR has engineered a larger housing for use in the Stage III GTX Turbocharger System.

To aid in accurate airflow readings, the APR MAF housing features a long, precision-machined tunnel with a honeycomb airflow straightener. APR’s Electrical Engineers make appropriate coding changes to the ECU to understand the larger MAF housing while the calibration experts update the ECU with all of the necessary calibration data surrounding the larger housing’s physical properties. The end results are accurate readings and a further refined driving experience.

The MAF housing includes a CNC-bent mounting bracket for a sturdy connection to the engine bay and additional wiring and couplers are included to extend the factory MAF sensor’s harness.

Silicone Hoses

 

Wire reinforced, multi-ply silicone hoses provide an unrestricted path for airflow to enter and exit the turbocharger. The ultra rigid design ensures boost and vacuum piping will not swell or collapse causing leaks and restrictions in the induction and charge piping system supporting boost response and turbo recovery. Each hose is engineered to fit properly into the vehicle’s engine bay with all necessary emissions and reference ports securely affixed.

APR’s Easy-Flow Silicone Hose design features stepped mounting surfaces for smooth transitions from one pipe to another. Traditional designs simply sit on top of each other, often resulting in a disruptive airflow path. By using the stepped design, hoses fit properly without airflow restrictions, resulting in the most ideal path for moving air through the turbocharger and into the engine.

Oil and Coolant Lines

APR’s oil and coolant lines are specific to the APR Stage III GTX Turbocharger System and provide years of leak free operation. The lines feature a flexible braided stainless steel construction with CNC mandrel bent hard-lines for specific and clean routing as if intended by the OEM. Every detail is important, and APR goes the extra mile to ensure any possible weaknesses are eliminated.

Downturn and Downpipe

An investment cast 3” stainless steel downturn provides a smooth and uninterrupted path for exhaust gases existing the turbocharger at high velocity. The high temperature resistant stainless steel design increases the components strength without fear of component failure even under the most grueling environments.

APR’s 3-inch T304 stainless steel downpipe connects seamlessly to the supplied downturn and is fully compatible with APR’s turboback exhaust system, full downpipe, or midpipe exhaust system.

Diverter Valve Housing and Wastegate Solenoid Bracket

The factory turbocharger features a diverter valve (DV) and wastegate solenoid (N75) directly mounted on the compressor housing, which is removed for the more powerful APR Stage III GTX Turbocharger Unit. As such, APR provides a CNC-machined billet-aluminum DV housing and CNC-bent N75 bracket to conveniently relocate these items within the engine bay.

The DV housing is anodized clear to protect against corrosion and the internal mounting surface is precision machined identically to the OEM unit, to ensure a proper, leak proof design.

Vacuum Lines

APR provides new vacuum lines and T-junctions. Leak proof connections are easily achieved thanks to the included OEM style crimp clamps.

Gaskets

APR doesn’t cut corners even with the most mundane details of the kit. Every nut, bolt, stud, washer, clamp, and gasket necessary for the install is included with the kit.

Spark Plugs

To cope with raised cylinder pressure and temperature, four NGK Laser Platinum Premium plugs are included. The plugs operate at a heat range colder than stock, which results in better pre-detonation resistance under extreme conditions. With these spark plugs in, APR’s calibration engineers were able to safely achieve more power, especially in extremely demanding conditions.

Install Manual

Dyno Testing

Horsepower and Torque was measured in APR’s in-house, soundmaster dyno cell, using a dynapack all-wheel dynamometer. Multiple stock and modified runs were conducted and the SAEJ1349 corrected results were averaged together to represent the differences between a stock and APR Stage III GTX 2.0 TSI.

APR Releases 3rd Gen. 2.0 TSI ECU Upgrade!

Posted on January 28, 2014 – 9:00 am

Achtuning is pleased to present another world wide first from APR!  APR has released the ultimate engine control unit (ECU) upgrade for the Generation 3, 2.0 TSI engine.  APR’s ECU upgrade is available in octane-specific variations and is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU.

The Continental SIMOS 12 engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.

APR’s Calibration Engineers spent months calibrating the engine management system, including many hours of in-house chassis dyno development. With a thorough understanding of the ECU’s torque structure, APR’s Calibration Engineers properly increased engine load to produce more power and torque from idle to redline. APR’s ECU Upgrade increases turbocharger boost pressure and optimizes cam timing, ignition timing, lambda and more to produce higher output. Using APR’s proprietary high-speed data logging suite, the calibration team closely monitored the effects of these changes to ensure a powerful ECU upgrade without derogating the engine’s drivability or reliability.

APR’s ECU Upgrade will provide an excellent leap in power and torque while retaining OEM knock control sensitivity and other built in safety features. The result is safely achieved power, optimized for various fuel grades found around the world. We call it Performance Without Compromise!

APR Stage I ECU Upgrade


The APR Stage I ECU Upgrade is designed to work without requiring other changes to the vehicle’s hardware. With the ECU Upgrade alone, APR’s Calibration Experts measured higher peak figures of 302 ft-lbs of torque and 261 horsepower with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 67 ft-lbs of torque and 52 horsepower. Even higher figures were acheived using 100 AKI octane race fuel. The increase in power directly translates to an exceptionally quicker vehicle. Using advanced GPS measuring devices, APR’s engineers conducted several acceleration tests. During the 60-130 MPH sprint, the APR Stage I equipped vehicle crossed the finish line 4.829 seconds quicker, resulting in an excellent 20.66% improvement!

APR’s ECU upgrade is the best power per dollar modification for the new 2.0 TSI engine and takes the vehicle’s performance to similar levels typically reserved for higher output, sporty models, without pushing the limits. With factory-like smoothness and drivability, APR’s ECU upgrade will fill the void in an otherwise excellent vehicle.


Acceleration Enhancements:
Beyond power and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle through other calibrations changes. Ignition delay is reduced resulting in a more responsive pedal without altering overall throttle sensitivity. Furthermore, drivability was greatly improved by reducing the throttle lag commonly noticed at slow speeds and while reapplying throttle after decelerating.


Left Foot Braking / Brake Boosting:
APR’s Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped vehicle’s throttle input is disabled while pressing the accelerator and brake at the same time. Left Foot Braking, a common motorsport driving technique, allows the driver complete control over the vehicle’s throttle and braking system, which may give the vehicle the edge it needs at the track. As is with all features APR adds to the ECU, this feature may be removed upon request.


Clutch Protection:
APR’s standard Stage I ECU Upgrade offers a large increase in low-end torque, which may overpower the factory clutch. While APR did not experience clutch slip at the advertised torque levels and even higher, others may due to clutch health and driving style. APR recommends upgrading slipping clutches, but has also created special software designed to deliver the same peak horsepower with a cap on low end torque to reduce or eliminate slipping. These specific files are available with various torque caps set lower than the standard Stage I ECU Upgrade.


Speed Limiter:
APR’s ECU upgrade increases the vehicle’s top speed limiter for blistering sprints around the track or across the Autobahn without the speed limiter shutting down the fun!


Increased Fuel Economy:
APR’s Calibration Engineers paid close attention to several parameters directly related to fuel economy, especially while cruising at highway speeds. Depending on driving style and fuel quality, better miles per gallon may be achieved!

APR’s proprietary ECU Composer is used for altering the engine management system. With full access to every table, map and variable within the ECU, APR’s Calibration Engineers are not limited to a handful of maps as is common for most tuning companies. ECU Composer takes calibration to a new level with APR’s Quick Flashing. APR’s Calibration Engineers can reflash the ECU in seconds rather than waiting lengthy periods of time between each flash.

APR ECU Assembly:

APR’s Electrical Engineers have the ability to alter the code structure of the ECU. Through code levels changes, APR’s Engineers are able to add features to the ECU. Other changes allow higher torque limits than those achievable through only modifying calibration data or using piggyback devices as is the case for many tuners. This allows APR’s engineers to often not require transmission software to meet or exceed advertised gains. On the highly modified end, this allows APR to make turbo upgrades operate as if intended by the OEM.
