APR TCU Transmission Performance Software For Audi 8-Speed (AL551 ZF8)

The APR TCU Upgrade unlocks a significant power increase for the 3.0T supercharged engine, boosting horsepower by an impressive 25-35 HP. By raising shift points by up to 1,000 RPM, this upgrade fully optimizes the engine's powerband. Faster upshifts and downshifts are now achievable in all driving modes, with the added benefit of AMAX (Maximum Acceleration) mode, which maximizes torque output between shifts during vehicle launches.

Launch control is also optimized, allowing for increased torque off the line and faster acceleration. The upgrade increases clamping pressure and torque capacity, ensuring the transmission delivers peak performance, even under extreme conditions such as high-grip launches and consecutive AMAX shifts. Additionally, torque cuts between shifts are refined to deliver a sportier, more responsive driving experience by eliminating the sluggishness often associated with this transmission compared to sportier dual-clutch systems.

We've also focused on improving overall drivability, smoothing out the usual quirks and complaints to provide a seamless driving experience. Each TCU upgrade is tailored to your specific ECU stage, and we offer free stage transitions, ensuring the upgrade evolves with your setup.

The installation is straightforward, loading the software directly to the factory TCU through the OBD-II port for a clean, hassle-free process.
