Built for the EA824 & EA825 platform in the Audi RS6 Avant, Audi RS7 Sportback, and Audi S8 & more, this Stage 2 TCU package is designed to handle increased power from upgraded hardware and push the gearbox to its full potential.
This is where the transmission matches the engine.
Stage 2 Gearbox (TCU) Tuning
A more aggressive, performance-focused recalibration of the transmission control unit.Built to manage higher torque levels and deliver faster, more decisive shifts under load.
Required setup
Stage 2 ECU tuning
Upgraded airflow and fueling (downpipes, intakes, HPFP)
What’s included
Advanced TCU remap (Stage 2 calibration)
Further increased clutch pressure for higher torque capacity
Faster, more aggressive shift speeds
Optimised shift points for performance driving
