DL501
TCU tuning for the 7-speed S tronic (DL501) gearbox.
What it is
Gearbox (TCU) tuning adjusts the transmission control unit rather than the engine. We raise torque limits so the box can handle the extra power, and sharpen shift speed and firmness where the gearbox allows. This is done per transmission type so the behaviour suits your car.
