Audi SQ5 Owners! It’s your turn!!

Posted on July 10, 2014 – 9:00 am

Achtuning is pleased to present the ultimate engine control unit (ECU) upgrade for the Audi SQ5 3.0 TFSI V6.  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 8.5 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 red-line.  APR’s ECU Upgrade increases supercharger 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 403 horsepower and 371 ft-lbs of torque with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 50 horsepower and 43 ft-lbs of torque.  Even higher figures were achieved using 100 AKI octane race fuel.  The increase in power directly translates to an exceptionally quicker vehicle.

For those demanding more torque and power, the APR Supercharger Pulley Upgrade is the answer.  Spinning the supercharger faster increases air flow allowing for higher boost levels and more power.  The gain in torque is felt immediately, but the results are present across the entire power-band. Expect 419 horsepower 93 AKI octane fuel and 445 horsepower on 100 AKI octane race fuel!  Software is included as a free upgrade for APR Stage I customers with the purchase of an APR Supercharger Pulley Upgrade.

APR’s ECU upgrade is the best power per dollar modification for the new 3.0 TFSI 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.

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!

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!

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.

The APR Development Difference

APR DirectPort Programming:

APR’s patented DirectPort Programming is now available for the Simos 8.5 ECU!  With a simple connection to the Internet we have direct access to APR’s latest ECU upgrades for loading directly over the vehicle’s OBD-II port.  This completely eliminates the need to remove and open the ECU for currently available files and can be uninstalled at any time!

APR ECU Explorer:

APR’s proprietary ECU Explorer gives APR’s Calibration Engineers unparalleled access to the vehicle’s entire engine management system.  Typical commercially available data logging tools, used by most tuners, only allow logging up to 12 engine-operating variables at extremely low data rates.  These tools are also limited to a small, specific list of variables.  APR’s ECU Explorer is capable of logging every variable found within the ECU.  It’s capable of logging well over 100 variables at once with data rates as high as 100 samples per second.  Synchronous data logging is available for fine-tuning.

APR ECU Composer:

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.

APR B8 S5 4.2L FSI V8 Stage III+ TVS1740 Supercharger System

Posted on April 17, 2014 – 9:00 am

Achtuning is excited to announce APR’s release of their Audi (B8) S5 4.2L FSI V8 Stage III+ TVS1740 Supercharger System!

APR’s technical reach has grown enormously since opening in the 1990’s and currently represents a force of unmatched performance without compromise in the performance enhancement sector for Audi vehicles. Our previously available APR Stage III TVS1320 Supercharger System found its way on to several hundred S5s and RS4s around the world, making it the most popular and reliable system on the market. With more than four years’ worth of 4.2L FSI V8 supercharger engineering research, development and testing, APR’s new Stage III+ TVS1740 Supercharger System represents the pinnacle of Audi’s German engineering enhanced by APR’s American ingenuity.

In the factory form, Audi’s S5 4.2L FSI V8 leaves much to be desired compared to recent models proudly displaying the S badge. The APR Stage III+ TVS1740 Supercharger System fills the void by adding an average of roughly 45% more horsepower and torque across the entire power band. The results are nothing short of amazing; taking the S5 from 353 horsepower to 589 horsepower on pump fuel and 635 on race fuel without breaking a sweat! With up to 542 FT-LBS on tap thanks to the TVS1740’s positive displacement supercharger, expect instant acceleration with absolutely no lag commonly associated with other forms of forced induction.

Supercharger and Manifold

At the heart of the APR Stage III+ Supercharger System is Eaton’s latest Twin Vortices Series (TVS) supercharger unit, the TVS1740. The supercharger system is a positive displacement, roots style pump, utilizing Eaton’s lightweight, four-lobe 160 degree twisted rotors. Cast and assembled as a single, OEM-style-manifold and rotating group housing, the unit is quiet, compact, attractive, easy to install, and requires little to no extra maintenance to the unit itself.

The positive displacement supercharger offers power instantly as the throttle is pressed. Boost pressure builds with no perceived lag commonly associated with other types of forced induction, and provides a large increase in torque across the entire power band. Throttle control is linear and predictable and makes for an excellent driving experience both in daily driving and wide-open acceleration.

Since the supercharger does not compress air as it moves through the roots, it’s extremely efficient during light throttle and cruising situations. Unlike screw-type positive displacement superchargers that are always compressing, the TVS unit can internally bypass unwanted air, resulting in negligible parasitic loss during cruising and thus far greater fuel economy.

The single cast unit and appropriately sized rotating group eliminates potential leak points and allows for a slim, compact design without sacrificing key airflow design characteristics. The unit features a high velocity flow path through the supercharger rotors and an unrestricted discharge port into the appropriately sized plenum. The large plenum equalizes flow across all ports as air feeds evenly through the low-pressure-drop, dual-internal air-to-water heat exchangers. Finally, the ports are separated into individual runners, offering greater operation by eliminating cross talk.

Internally the dual heat exchangers offer technological advances shared by Formula 1 teams around the globe. Each unit features a louvered fin design, which minimizes pressure drop while achieving excellent cooling effectiveness. The extruded multi-rib tubing maximizes heat extraction to be carried away through the large bore coolant recirculation hard lines. Externally, supercharger coolant is pumped through a large front mounted heat exchanger where it’s cooled and circulated back through the charger again.

Engine Management

The factory Bosch MED 9 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+ TVS1740 Supercharger System, APR’s Engineers spent months calibrating the engine management system, including well over 100+ 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. Further development was performed putting the vehicle through performance evaluation and durability testing at the drag strip. 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.

Adding forced induction to a naturally aspirated engine presents several challenges with regards to how the ECU operates. APR’s Calibration Engineers properly restructured the engine’s volumetric efficiency (VE) model to properly determine the ECU’s calculated load. 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, are adjusted to handle the large temperature variances compared to a factory naturally aspirated setup.

APR’s Calibration Engineers have optimized cam timing, ignition timing and lambda to provide tremendous leaps in power while retaining OEM knock control sensitivity. 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.

Beyond power and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle through other calibration changes. 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 the factory set redlines without dropping off several hundreds of RPM earlier. And lastly, APR’s tried and tested 4,200 RPM Motorsport Launch Limiter allows the driver to focus on launching the vehicle, rather than controlling the engine speed.

Beyond wide open throttle performance, APR’s Calibration Engineers spent countless hours optimizing vehicle drivability under daily, part-throttle, driving. The vehicle’s pedal maps are recalibrated under both standard and sport mode, providing smooth part-throttle drivability without compromising the driveshaft windup protection. 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! We call it Performance Without Compromise.

Front Mount Heat Exchanger

APR’s supercharger system features a large, 480mm x 335mm x 45mm, front mount heat exchanger responsible for cooling coolant as it’s pumped out of the supercharger’s dual internal air-to-water heat exchangers. This is a critical component in any supercharged application to not only keep power consistent, pull after pull, but also to help keep IAT below dangerously high levels. The heat exchanger is specific to the S5 platform, featuring a hand welded design and CNC, laser-cut brackets to provide a simple and clean method of mounting to the vehicle.

Coolant Tank

APR’s supercharger system features a 4.2L coolant tank designed to increase the cooling system’s thermal capacity. During hard sprints around the track, the supercharger’s cooling system is working overtime to cool IATs and in doing so, the supercharger’s coolant temperature rises. With increased capacity, the time it takes to raise the supercharger’s coolant increases, resulting in a lower delta T, cooler IATs, and more power. For the track enthusiast, this means longer sessions and more continuous laps, under wide-open throttle, without loss of power.

Coolant Pump and Harness

APR’s coolant pump connects to the supercharger coolant circuit and continuously circulates coolant through the supercharger’s dual internal air-to-water radiators and APR front mount heat exchanger. The pump provides adequate coolant flow through a system of this size. The pump seamlessly connects to the factory wiring harness through the included APR wiring harness with no wire splicing and is triggered by the included relay system. APR’s CNC, laser-cut bracket provides a simple and clean method of mounting the pump to the vehicle.

MAF Sensor & Housing

The factory engine management relies on load calculations derived from the mass airflow (MAF) sensor to properly control the engine. Unfortunately the factory MAF sensor becomes saturated and unable to read and correctly report the high airflow levels generated by the APR supercharger as it was designed for an engine originally creating far less power.

APR provides a new MAF sensor and precision-machined MAF sensor housing to aid in accurate airflow readings. APR’s Electrical Engineers make appropriate coding changes to the ECU to understand the new MAF setup while the calibration experts update the ECU with all of the necessary calibration data surrounding the sensor’s and housing’s properties. The end results are accurate readings and a further refined driving experience.

High Pressure Fuel Pumps


Sold separately as brand new pumps or rebuilds of the engine’s existing pumps, the APR High Pressure Fuel Pumps address fueling needs and leave plenty of headroom for safety and further increased power levels. By increasing the pump’s internal capacity, the fueling system is capable of displacing a higher volume of fuel per minute at every RPM.

Coolant Expansion Tank

The APR coolant expansion tank is used for filling the supercharger’s cooling circuit and for handling liquid expansion under various operating temperatures. The tank is cut from a single block of aircraft grade 6061 aluminum billet, is anodized black and proudly displays the APR logo. APR’s CNC, laser-cut bracket provides a simple and clean method of mounting the expansion tank to the engine bay.

Fueling Hardware

APR’s supercharger system varies greatly from the OEM intake manifold design, and for fitment’s sake, depending on vehicle year, some of the factory high pressure fueling system must be modified. The fuel rails and other high pressure and low pressure direct injection fuel lines are replaced with new, low profile, OEM parts on the pre November 2008 vehicles. All OEM safety equipment remains intact.

An APR high-pressure rail relief valve allows the system to operate at greater rail pressures, resulting in a reduction of injection on-time which translates to more ignition advance and greater power.

The kit also includes all new high-pressure fuel pump low-pressure fittings and replacement injector O-rings.

Spark Plugs

To cope with raised cylinder pressure and temperature, eight NGK Iridium IX spark 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.

Intake Air Temperature Sensor and Harness

APR’s Supercharger System significantly increases airflow through the engine, and is capable saturating the factory mass airflow sensor (MAF). As such, the sensor is unable to correctly report critical operating information to the ECU, resulting in incorrectly calculated load and poor operation. Simply adjusting the factory sensor and calibration will result in a calibration that’s only correct in a small operating window, resulting in a poor compromise.

Because the sensor is absolutely critical for safe, reliable and powerful operation and as such, APR provides a new MAF sensor capable of reading airflow levels beyond the operational range of the APR Supercharger System. APR’s Engineers account for this new sensor in the factory engine management system as simply adding the sensor alone is not permissible. The new sensor accurately reads airflow levels and provides the ECU with the correct information necessary control the engine.

The sensor’s design differs from the factory unit, and as such APR provides a precisely CNC-machined billet aluminum MAF housing to enclose the unit. The sensors placement and the MAF housing’s diameter are taken into great consideration to ensure proper airflow measurement.

The included harness allow for simple integration into the OEM wiring harness.

Coolant Lines

The APR Supercharger System features dual internal air-to-water radiators designed to reduce intake air temperature, (IAT), before entering the cylinders. With cooler IAT, the ECU will request more ignition advance and result in more power.

APR reinforced rubber coolant lines feed the Supercharger’s internal cooling system, which provides a circuit between the included APR front mount heat exchanger, APR coolant pump and APR expansion tank.

All necessary brass connectors, spring-loaded clamps and OEM style crimp clamps are included. Additionally some engine coolant lines are updated while installing the supercharger system and are included with the kit.

Fuel Lines

To accommodate the large APR Supercharger, modifications are made to the low-pressure fueling system and evap lines. Each fuel line exceeds CARB and EPA ratings and includes a patent-pending GreenShield barrier. The multi-ply, reinforced rubber hoses are designed to protect against today’s modern deteriorating fuels and include a best-in-class working psi of 225.

OEM style spring clamps and crimp clamps are included to ensure a solid connection. To help provide a neat and appealing install and assist in abrasion resistance, nylon braid hose cover and shrink-wrap is included.

Vacuum Lines

To accommodate the transition from naturally aspirated operation to forced induction, APR provides new vacuum lines and T-junctions. Leak proof connections are easily achieved thanks to the included OEM style crimp clamps.

Pulleys and Belt

The supercharger system’s internal rotors are rotated via a belt and pulley attached to the engine’s accessory drive system. The included 5pk belt and OEM idler pulleys ensure a proper connection to drive the supercharger.

N80 Harness

Several OEM components are moved during the install of the supercharger system, and as such, APR provides an OEM style extension harness to connect components without modification to the factory wiring harness.

Gaskets

New OEM gaskets and bolts are provided to facilitate a leak proof connection between the cylinder heads and APR Supercharger unit.

Misc. Hardware

The included core support bolts allow the vehicle’s front end to be placed into the service position. In doing so, the install process is made much easier thanks to the added space in the engine bay.

The included factory style zip-ties aid in securing various lines moved during the install and to replace factory zip-ties removed during the install process.

Padding material protects items from damage during the install process.

Install Tool

On post November 2008 vehicles, a specific tool is included to aid in installing the supercharger.

Install Manual

APR has a worldwide network consisting of many professional shops capable of performing an APR supercharger system install. To accompany APR’s world-class technical support hot line, APR includes a full, printed, step-by-step install manual to make the install process smooth and simple!

Dyno Testing

Horsepower and Torque were measured in APR’s in-house, sounmaster dyno cell, using a dynapack all wheel drive 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+ B8 S5. Crank power figures were estimated based on Audi’s factory advertised results.

Acceleration Testing

All too often performance upgrades show improvements during a single dyno pull, but lack the ability to show the same performance in real world conditions. Furthermore the dyno may be unable to illustrate the system’s response and other tuning changes designed to make the system instantly react to the drivers input. Through acceleration testing, APR’s engineers were able to improve power delivery during launches, after gear changes and prove the cooling system was up to the task of shedding heat to keep power consistent.

APR’s local certified quarter mile drag strip is a perfect and safe testing ground for high speed, 130+ MPH sprints. Using Car and Driver magazine’s measured results as a benchmark, APR’s Engineers set out to prove the Stage III+ Supercharger System was capable of increasing the S5’s performance substantially.

Car and Driver magazine measured the B8 S5’s quarter mile performance in an underwhelming 13.4 seconds at 105 MPH. However, with the addition of the APR’s Stage III+ TVS1740 Supercharger System, the vehicle entered a league of performance often shared by exotic supercars. Using 93 octane fuel the same acceleration test was completed 2.2 seconds sooner and 19.68 MPH faster! Through testing higher octane fuelsthe gap grew even larger, ultimately resulting in an astonishing 18% reduction in time.

Many more acceleration tests were performed, including record setting quarter mile passes, proving an APR Stage III+ TVS1740 Supercharger System is the ultimate upgrade for B8 S5!

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.
