APR has just released their proprietary light-weight, high-strength forged OEM profile MAHLE pistons and connecting rods for the 2.5 TFSI engine!
As the leader in high performance engine products for the Volkswagen Automotive Group, APR is capable of creating horsepower and torque levels outside of the original equipment’s stress tolerances. In such cases, it’s highly recommended and in some cases necessary to upgrade additional engine components to cope with the increased load. APR’s Connecting Rods raise the engine’s stress tolerance levels to provide years of continued reliable operation without compromise.
APR’s proprietary connecting rods feature premium, certified USA-Made 4330 alloy, chosen for its lightweight and high-strength properties compared to 4340 or other inferior alloys sourced from undisclosed locations around the world. To ensure the highest level of quality control, the entire process from initial design to finished product, including materials, forging, treating and 100% CNC machining all take place in the USA. APR only uses strict manufacturing guidelines in some of the finest manufacturing facilities in the industry to deliver unmatched quality and integrity with each rod produced.
- Tapered H-Beam Design - Strong weight saving design
- 4330 Alloy Construction - High strength and light weight alloy
- AMPCO 45 Bushing - Exceptional wear resistance
- Wrist Pin Oil Passage - Additional wear resistance
- Magnaflux Tested - Casting quality control
- Rockwell Tested - Hardness testing
- Diamond Honed - Surface finishes with consistent RA
- Balanced to +/- 1 Gram - Increased reliability & performance
- Tolerances to Factory Specs - OEM quality fit
- Double Re-Melt Forging - Improves metal quality

The connecting rod is designed to handle power levels far beyond the original component’s ratings in order to ensure reliability with years of continued use. Increasing rod strength often comes at the expense of increased weight, which ultimately reduces engine efficiency. To generate a balance between strength and weight, APR tested and analyzed several designs in addition to using premium alloys, advanced forging techniques and multiple strengthening treatments. APR’s Engineering Team’s design requirements resulted in a tapered H-beam design, offering exceptional strength due to the H design and weight savings from tapering, a trait most commonly associated with an A design.
We call it Performance Without Compromise.
Weights and Application
MS100070 – 2.5 TFSI – CEP – 22mm Wrist Pin – 501g Including Hardware – Drop In Rod for OEM Piston or APR’s Mahle Motorsport Pistons
The wrist pin end of the rod features a wear resistant bushing material made from AMPCO 45 – a high strength alloy with mechanical properties beyond that of commercial nickel-aluminum bronzes. Wear reduction is further enhanced via a pin lubrication access point at the top of the rod, feed by the engine’s oil squirters. For further weight reduction and drop in rod compatibility with OEM and APR pistons, the wrist pin end is tapered.
When modifying an engine for strength and longevity, quality is of the utmost importance. APR’s Engineering teams have ensured each rod is created with absolute quality and control in mind each step of the way. Tolerances are kept to OEM specs and the rods are balanced to within +/- 1 gram. Furthermore the rods undergo rigorous tests to backup the entire manufacturing process. Rockwell testing provides a method for testing hardness while Magnaflux or Magnetic Particle Inspection, offers a method for detecting interruptions in the physical continuity of the casting. The result is a product you can trust.
Mahle Motorsport VP2 Rod Bearings
When upgrading connecting rods, it’s necessary to replace the existing connecting rod bearings. APR recommends using Mahle Motorsport VP2 rod bearings for their superior strength and wear resistance properties and attention to detail over the similarly priced OEM bearings.
Each bearing is capable of taking abuse in the magnitude of 14,500 psi while still offering superior conformability and fatigue resistance not commonly seen elsewhere in the market. This is partially due to the bearing’s high-grade hardened steel backing with bronze substrate and lead/indium overlay. Laser etched part numbers rather than typical stampings aid in significantly improved heat transfer and prevention of shell distortion. Formula 1 standards dictate extremely high tolerances, while Mahle’s attention to detail and chose of fine materials ensure worry free operation.
Mahle Motorsport German Tool Steel Wrist Pins
For ultimate strength and reliability, APR recommends upgrading to Mahle’s German tool steel wrist pins while upgrading connecting rods. If ordering APR’s Mahle Motorsport Pistons, wrist pins are included.
Connecting Rods Set – MS100070 – $1,299.99 – 2.5 TFSI – CEP – 22mm – 501g including hardware – Drop In for OEM Piston or APR’s Mahle Motorsport Pistons
Mahle Motorsport VP2 Rod Bearing Set – Z1002377 – $199.99
Mahle Motorsport German Tool Steel Wrist Pin Set – MS100074 – $159.99 – 22mm
Set of 5. If ordering APR Pistons, replacement wrist pins are included.
APR’s proprietary light-weight, high-strength forged OEM profile MAHLE pistons for 2.5 TFSI engines
The introduction of direct injection played a significant role in piston combustion bowl design. The profile ultimately affects the swirl and tumble of the air/fuel mixture making the design critical for the most efficient use of the fuel. APR worked with MAHLE, a VAG Tier 1 supplier for OEM pistons, to design a proprietary piston sharing the OEM profile along with other strength and weight saving properties.
- Forged pistons
- Proprietary APR / MAHLE design
- Proprietary MAHLE 142S alloy
- Low noise materials
- Low thermal expansion for tighter tolerances
- OEM piston compression bowl profile
- 83mm oversized design
- 10.1:1 compression ratio
- MAHLE 22mm German tool steel wrist pins included
- MAHLE low-drag rings included
- Top – Barrel-Faced Steel (File to Fit)
- Second – Tapered Face Ductil Iron (File to Fit)
- Oil Rings – 3 Piece Standard Tension
- 320 grams per piston
- Hard anodized top ring grooves to prevent micro-welding
- MAHLE proprietary Grafal anti-friction coated skirts
- OEM oil squirter notches
- First landing accumulator grooves for top ring seal promotion
- Ultra flat ring grooves for ring seal promotion
The piston is designed to handle power levels far beyond the original component’s ratings in order to ensure reliability with years of continued use. Increasing piston strength often comes at the expense of increased weight, which ultimately reduces engine efficiency. To generate a balance between strength and weight, APR pistons are forged from MAHLE’s proprietary 142S alloy and treated with other MAHLE proprietary coatings. This material is stronger than the common 4032 alloy, provides quieter operation than 2618 alloy and maintains tighter piston to cylinder wall clearances thanks to the material’s low expansion rates. The piston’s grey phosphate coating acts as a dry lubricant to protect against galling and micro-welding while MAHLE’s proprietary Grafal skirt coating reduces drag, scuffing, friction, wear and noise.
To maintain the OEM piston profile, compression is raised roughly .1 due to the half mm overbore. APR’s engineering teams chose the 10.1:1 compression ratio after spending several years testing the affects on knock tolerance and off-boost operation from different ratios on VAG direct injection engines. APR explored altering the compression ratio, but were unable to locate any advantages in doing so.
APR pistons are designed for 83mm bore diameter, a half millimeter over the OEM units and as such are not drop in compatible. The larger piston diameter provides in an increased engine displacement from 2,480 cc to 2,511 cc. The slight increase in displacement and reduction in friction provided by the included high-performance, low-drag rings frees up horsepower. To remove any imperfections in the cylinder walls and to provide a new, compatible sealing surface for the upgraded rings, a first overbore must take place. APR does not recommend drop in pistons at this level of internal engine modification.
APR pistons include upgraded 22mm German tool steel wrist pins for ultimate strength and reliability.
The pistons are fully compatible with APR’s MS100070 connecting rods.

APR has debuted their Audi (B7) RS4 4.2L FSI V8 Stage III+ TVS1740 Supercharger System!
Achtuning is pleased to present APR’s NEW Audi (B7) RS4 4.2L FSI V8 Stage III+ TVS1740 Supercharger System! Since the release of the B7 RS4, Audi’s technological advances on RS models have grown dramatically. However, this often came along with the removal of traditional manual 6-speed transmissions many RS owners have grown to love. APR quickly realized the RS4 represented one of Audi’s last great performance sedans and chose to continue advancing the platform more than half a decade after the last RS4 rolled off the production line.
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. Their previously available APR Stage III TVS1320 Supercharger System found its way on to several hundred RS4s around the world, making it the most popular and reliable system on the market. With more than four years’ worth of RS4 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 older high revving FSI V8 leaves much to be desired compared to some of the latest technological advances brought forth by Quattro GmbH in recent years. The APR Stage III+ TVS1740 Supercharger System fills the void by adding an average of roughly 40% more horsepower and torque across the entire power band. The results are nothing short of amazing; taking the RS4 from 414 horsepower to 626 horsepower on pump fuel and 688 on race fuel without breaking a sweat! With more than 500 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.
APR Stage III+ TVS1740 Supercharger Components
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.
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 hundred RPMs 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, 310mm x 540mm x 42mm, 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 RS4 platform, featuring a hand welded design and CNC, laser-cut brackets to provide a simple and clean method of mounting to the vehicle.
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.
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 leaves 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.
Throttle Body Hose and PCV Bracket
A wire reinforced, multi-ply silicon hose is provided to connect the throttle body to the intake housing. The ultra-ridged design ensures the hose will not collapse under the tremendous vacuum created by the supercharger system’s forced induction. The hose is engineered to fit properly into the engine bay with the necessary ports securely affixed by OEM style crimp clamps.
A laser-cut, CNC-bent, PCV hose bracket with retained fasteners is provided to secure the factory PCV pipe to the repositioned throttle body.
APR’s supercharger system varies greatly from the OEM intake manifold design, and for fitment’s sake, 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. 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, replacement injector O-rings, and OEM style extension harnesses requiring absolutely no splicing of the factory harness.
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
The factory mass airflow sensor includes an intake air temperature (IAT) probe and is designed to provide the engine control unit (ECU) with air temperature information. Because the RS4 is converted from naturally aspirated to forced induction, the sensor must be relocated to ensure proper IAT measurement. The IAT sensor is absolutely critical for safe, reliable and powerful operation and as such, APR provides an OEM sensor and harness for placement just past the supercharger’s dual internal air-to-water radiators. The included harness allows for simple integration into the OEM wiring harness.
The sensor feeds correct IAT readings to the ECU, which provides closed loop control over various calibration decisions, such as desired ignition advance. This provides safe operation no matter what the condition. During a cold day, with lower supercharger coolant temperature, the ECU will safely increase engine output mainly through ignition. However, under hot conditions, such as a vehicle seeing plenty of track time, the ECU will compensate for these conditions, lowering output slightly to avoid dangerous premature detonation. These compensations result in only attempting to safely achieve the maximum amount of power capable during any given temperature related scenario.
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.
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.
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.
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.
New OEM gaskets and bolts are provided to facilitate a leak proof connection between the cylinder heads and APR Supercharger unit.
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.
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!
Horsepower and Torque was 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+ B7 RS4. Crank power figures were estimated based on Audi’s factory advertised results.

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 sheading 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 setout to prove the Stage III+ Supercharger System was capable of increasing the RS4’s performance substantially.
Car and Driver magazine measured the B7 RS4’s sprint from 30-130 MPH in an underwhelming 17.2 seconds. 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 6.64 seconds faster! Through testing higher octane fuels, and eventually weight reduction and tire changes, the gap grew even larger, ultimately resulting in an astonishing 48.2% reduction in time.
Many more acceleration tests were preformed, including record setting quarter mile passes, proving an APR Stage III+ TVS1740 Supercharger System is the ultimate upgrade for B7 RS4!

APR EMCS Programs and Features
APR’s patented EMCS, Enhanced Modular Chipping System, brings selectable programs and features to your factory ECU, all without the need to purchase external hardware. Other companies have attempted to imitate EMCS with clumsy external switching devices that only replace or multiply portions of a “base” calibration. However, EMCS has the ability to completely rewrite the entire operating map data, giving each map a complete set of calibration changes. APR’s EMCS features and programs modes are activated via your OEM cruise control buttons. Your cruise control will continue to function as normal.
Program switching allows the user to cycle through up to four different engine calibrations and operating modes all without the need for external hardware.
By selecting stock mode, the ECU calibration is reset to the factory calibration. The engine will run exactly as it did before purchasing APR software.
APR Performance Modes:
APR’s octane-specific calibrations are available for various premium and race fuels around the world. Each performance mode is a completely new calibration, altered specifically for the characteristics of the fuel quality selected.
APR’s Valet Mode protects your vehicle from becoming an expensive toy for unauthorized individuals. By enabling Valet Mode, the vehicle’s performance is extremely limited. Launch control is uneventful, the vehicles top speed is limited to roughly 40 MPH and the engine’s redline is reduced to nearly 5,000 RPM!
Fault Code Erase:
Fault code erase allows the user to erase and reset engine related trouble codes and ECU adaptation data without using a specialty tool.
APR Mobile is a simple yet powerful tool designed to enhance the APR tuning experience.
APR Mobile installs on smart phones, tablets and other devices and provides a wireless connection to the vehicle’s engine control unit or ECU. Once connected, the device can be used to access APR’s EMCS program switching features, read and clear fault codes and data log the ECU at high data rates not found on other commercially available tools. The app can also be used to access APR’s latest news articles, locate dealers in APR’s network and review previously saved data logging sessions.

The APR Development Difference
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 with APR Live Tuning:
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 on the 4.0T with APR’s Live Tuning. APR’s Calibration Engineers can test calibration changes with a single click of a button to instantly monitor the changes, rather than spending several minutes shutting down the vehicle to reflash the ECU. This allows a level of fine-tuning unmatched in the market.
APR ECU Assembly:
APR’s Electrical Engineers have the ability to alter the code structure of the ECU to add features not available from the factory. Through code levels changes, APR’s Engineers are able to add features designed to protect the gearbox during launch control. Other changes allow higher torque limit than those achievable through only modifying calibration data or using piggyback devices as is the case for many tuners. On the highly modified end, this allows APR to make Stage III Turbo Upgrades operate as if intended by the OEM. For most 4.0 TFSI owners, the advantage of this ability is the addition of APR’s patented EMCS Functions. EMCS puts the control of the engine’s operation at your fingertips and allows for additional features and options to be installed to your ECU.

Achtuning is excited to announce the much anticipated release of APR Mobile! APR Mobile installs on smart phones, tablets, and other devices and provides a wireless connection to the vehicle’s engine control unit or ECU – and WE HAVE THEM IN STOCK!! Once connected, the APR Mobile device can be used to access APR’s EMCS program switching features, read and clear fault codes and data log the ECU at high data rates not found on other commercially available tools. The app can also be used to access APR’s latest news articles, locate dealers in APR’s network and review previously saved data logging sessions. With direct access to the ECU, APR Mobile has the ability to support and interact with any functionality APR codes into the OEM ECU. That which is available today is only the beginning!
Data logging has proven to be an essential tool in vehicle diagnosis and learning the inner workings of the engine, but commercially available tools are slow and painfully limited. APR’s Mobile ECU Explorer has complete access to the inner workings of the ECU, similar to those available to APR’s calibration experts and OEM engineers alike.
APR Mobile Explorer is capable of wirelessly logging enough variables at once to get a complete overview of the engines current operating state and does so at sample rates fast enough for detailed analysis. For each supported ECU and engine type, APR’s engineers hand select operating values, which they feel are beneficial for your diagnosis needs. Should the need arise for access to more variables on new platforms, APR’s engineers can instantly push more variables to the phone without requiring the user to update the application.
APR Mobile Explorer can graph multiple items in real time and allow the end user to stop and recall the logging sessions to precisely read individual values in greater detail. Each log is automatically saved and can be emailed in a convenient .csv format for later analysis on desktop computers.
APR’s fault code erase makes diagnosis quick and simple. Should the vehicle ever throw a check engine light or fault code, the application will alert the end user with information related to the code.
Please call 425-895-0000 to schedule your APR Mobile specific ECU upgrade and pick up your APR Mobile “dongle” NOW from Achtuning!

Achtuning is pleased to present the Racingline range of parts developed by Volkswagen Racing UK and distributed exclusively through APR’s global dealer network! Upgrade your factory front suspension with the VWR Adjustable Drop Links. These were developed for APR’s race cars to allow them to lower the ride height yet keep the pre-load on the anti roll bar even. Additionally, by removing the soft rubber bushing from the factory links, cornering responses are sharpened.
This is an ideal upgrade for all cars running lowered suspension and/or up-rated anti-roll bars. A true race-car part, but with no compromise in daily driving.
Left / Right threaded ends make for easy length adjustment to eliminate pre-load and adjust the link length when changing between adjustment holes on your adjustable anti roll bar. Solid aerospace-quality rose joint ends replace the rubber bushing in the factory joint, so there is no compliance giving a direct connection to the anti roll bar. This can be felt through sharper turn in.
The VWR Adjustable Drop Links are a very universal product as they are fully compatible with any suspension and any anti roll bar products, not just the H&R and VWR upgrades we offer.
LH and RH thread Heat treated steel, Nickel plated high polish finish stainless steel insert with PTFE liner boned to the inner surface roller ball bearing Hardened and hard chrome plated maintenance free.
What is a Drop Link?
A drop link is a long bar that is used to attach the front anti roll bar ends to the brackets on the front shock absorber on most modern cars. On a lowered car, these fixed-length factory links push the anti roll bar ends down, and force the link to sit at a sharper angle.
Performance drop-links such as the VWR links utilize heavy duty steel ball joint ends that adjust & rotate to any angular combination. The light weight aluminium bodies (made from CNC Machined 7075 Aluminum) are finished in a beautiful anodised grey-blue coating.
The links provide 30mm center to center length adjustment. The link lengths are 300mm – 330mm (stock is 330mm).
The ball joint ends are the highest quality motorsport-specification heat treated nickel-plated steel, with high polish finish stainless steel inserts. The joints themselves have a PTFE liner bonded to the inner surface with hardened and hard chrome-plated maintenance free roller ball bearings. The links themselves have LH and RH thread at alternate ends.
For serious track use, the adjustment is used to fine tune the anti roll bar preload once the car is corner-weighted.

APR’s Engineering Teams have finished final testing of a new version (3.31) of Stage I, I+ and Stage II+ 2.0T ECU Calibrations for the Golf R. The new ECU Upgrade improves upon power deliver on top of what was previously a tremendous upgrade over stock! While addressing all previous concerns, additional motorsport features were added to further enhance your driving experience. The software revision is offered as a FREE update for all current APR ECU Upgrade customers! *
APR’s Calibration and Software Experts focused heavily upon increasing the overall drivability and performance of the 2.0T well beyond dyno numbers alone. Through implementation of the new patent pending APR Boost Control Strategy shared with our Stage III Turbocharger System, the ECU is now able to properly control boost pressure levels much higher than possible with the factory code alone. Specific calibration changes were made to enhance turbocharger spool rates, reducing lag to give the drive a more direct and connected linear feel to the accelerator pedal. Overall volumetric efficiency was enhanced through calibration changes resulting in more ignition advance towards redline, cooler exhaust gases, increased power and torque, and improved fuel economy depending on driving habits.
To further enhance your driving experience, APR outfitted the 2.0T with a Quattro GMBH inspired Motorsport Revlimiter as found on all other R and RS models currently being produced. Rather than softly slowing down acceleration several hundred RPM before the rev limiter, the 2.0T will now freely rev up to the new, clearly identifiable redline at 7,100 RPM and may make all the difference in a competitive head to head sprint on the track!
APR’s pleased to announce intake specific calibrations for use with high quality intake systems removing the factory engine cover, such as the Volkswagen Racing (VWR) Intake System. The factory Golf R’s intake is integrated into the engine cover, presenting a restrictive intake setup from the factory. APR’s Calibration Experts were able to extract more power from the engine by running the VWR intake system, which removes the factory cover. By removing the factory intake system, the engine’s operating parameters could be dramatically changed, but in doing so, other parameters were adjusted to ensure smooth operation with strict boost control, no throttle closure and surge avoidance in the low to mid RPM range. Expect more power and a better driving experience. Go APR!
