APR Motorsport - B8 S4 P1 during Practice at Road Atlanta
APR RS3 Testing at Road Atlanta| 10/30/2017
Following our successful outing at the drag strip, we headed to Road Atlanta for some brutal track testing. Testing on a road course puts the vehicle through some of the most demanding conditions. The engine is run at full tilt lap after lap, putting it through stress otherwise not seen on the road. In doing so, our calibration team is able to learn valuable information about how the engine handles the increased power in demanding situations our customers may experience. We tested each mode, Drive, Sport, and Manual, and were happy with the performance. Our RS3 was outfitted with our development APR 93 and Ethanol ECU Upgrades (as well as stock), APR 19×8.5 forged wheels with a previously used set of Pirelli Trofeo R tires, and APR Development Lowering Springs at full vehicle weight. We use Motul RBF660 brake fluid.
Race Report from our Driver, Ian Baas:
Thanks for a successful weekend everyone! The Car and Calibration was perfect and I've never been more excited about an APR release in my life. Most production street cars I've tested almost always show their weak points within 5-10 laps of any high performance track event. The RS3 Sedan excelled during the entire test and I am sure this product will perform flawlessly in street conditions as it sits currently!
I really cannot stress enough how much this car exceeded my expectations!
Best Time: RS3 Stage 1 (93 Octane Map) 1:45.60 (RA Wet/Dry Conditions)
S3 Stage 3+ (93 Octane Map) 1:39.10 (RA Dry

APR Porsche 2019+ Cayenne S / S Coupe 2.9T ECU Upgrades!| 09/09/2021
We're excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Porsche Cayenne S and S Coupe (9Y) 2.9 TFSI engine with the Bosch MG1 ECU! Expect massive gains with up to 484-538 HP and 521-590 FT-LBS of torque on tap, depending on octane, from this simple software upgrade.
APR's ECU Upgrades are the best dollar-per-horsepower modification one can make to improve engine performance. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR's optimization of the factory engine management system to take full advantage of the engine's capabilities, without needing any end user adjustment. The ECU Upgrades are available with various features and supported octane levels and each stage is compatible with most typical bolt-on modifications. The software is installed to the vehicle's factory ECU through the OBD-II port once the ECU is unlocked, resulting in a clean and headache-free install. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!
APR SQ7/SQ8 (4M) ECU Upgrade 4.0 TFSI EA825 V8 (North American Market)| 09/08/2021
We're excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Audi SQ7 and SQ8 4.0 TFSI V8 engine with the Bosch MG1 ECU! Expect massive gains with up to 685-767 HP and 731-804 FT-LBS of torque on tap, depending on octane, from this simple software upgrade.
Our new suite of MG1 ECU software comes after months of extensive research and development that is typically absent from the aftermarket. Our upgrade makes the engine more powerful and more exciting. We’ve extensively calibrated the system to work flawlessly on the track, while retaining safety routines to protect your engine in the most demanding scenarios. This was all made possible by our engineering team's pursuit of perfection. Development vehicles were outfitted with additional sensors, including turbo shaft speed sensors, thermocouples, transducers, and more, along with our high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After thousands of hours of testing and tuning we created new calibrations that are fine tuned for several octanes and contain hundreds of map changes, with a vast array of safety features built in.
