APR S4, S5, and SQ5 (B9/B9.5) ECU Upgrades are here!

April 3rd, 2020

We’re excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Audi S4, S5, and SQ5 (B9) 3.0 TFSI engine with the Bosch MG1 ECU! Expect massive gains with up to 431-480 HP and 467-549 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, including ethanol, and contain hundreds of map changes, with a vast array of safety features built in.

• Delivers up to 431-480 HP with 467-549 FT-LBS depending on octane
