      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 track days, acceleration tests, and dyno sessions, we created new calibrations that are fine tuned for several octanes, including ethanol, and contain hundreds of map changes, with a vast array of safety features built in.

      Dynos




      Our product page features 91, 93, 100, 104, and E60-E85 dyno graphs at the crank, wheels, and the full gain over the stock. Visit our product page to toggle through the graphs:

      How to Purchase

      This ECU must first be unlocked before software can be installed either by APR or an APR Dealer.

      If the ECU is locked, you have two options:

      Option 1: Send us your ECU

      Send us your ECU. We’ll unlock it, install APR software, and ship it back. The unlock process is free. Ground shipping to the continental USA is free. Follow these steps and watch the video for details on how to remove the ECU.

      Step 1: Purchase the ECU Upgrade.

      Step 2: Fill out this unlock form and select VW/Audi MG1 under unlock type.

      Step 3: Mail your ECU to APR, 4800 U.S. Hwy 280 W, Opelika, AL 36801, USA, and include the last 6 of your VIN on the outside of the box.


      Option 2: Visit an APR dealer

      Visit an APR Dealer and purchase the APR ECU Upgrade. They will remove and mail the ECU to APR. We'll unlock the ECU, ship it back. They'll reinstall the ECU, and install the software.

      Please note

      At no time during the unlocking process is the ECU opened or physically modified. If the ECU is flashed back to stock, it will need to be unlocked again. If the ECU currently has APR software, and there is an update, a new stage, new feature, or you want to switch octanes, software can be installed by an APR Dealer. Also, vehicle manufacturers issue many ECU part numbers and revisions throughout their vehicle lineup. As such, some ECUs may be temporarily unavailable as new parts and/or revisions are released. If the vehicle’s ECU part number and revision is known, availability can be checked at any APR Dealer or by contacting APR.

      Vehicle

      This release is currently only for the North American b9 RS5 2.9T. More vehicles, markets, and engine variations will be released in the coming days.

        Yes - There's more headroom too, just need more fueling. We're working on that now.
