TCU Tuning

Transmission and gearbox calibration for DSG, S-Tronic, ZF and selected automatic vehicles.

TCU Tuning and Gearbox Calibration

TCU tuning updates the transmission control unit so the gearbox works properly with the engine calibration. It is especially useful when ECU torque has been increased.

What TCU Tuning Can Improve

  • Shift speed and shift timing
  • Torque limiter settings
  • Clutch clamping pressure where supported
  • Launch control behaviour where applicable
  • Gear holding and kickdown behaviour

When It Is Recommended

TCU tuning is recommended when the gearbox is limiting torque, shifting too early, feeling lazy after an ECU remap or failing to make proper use of added performance.
