Gearbox tuning
A Stage 2 engine pushing through a stock gearbox calibration means clutch slip, torque intervention and blunted shifts. Our TCU files raise torque limiters, increase clutch clamping pressure, sharpen shift speed and adjust shift points to match the engine file.
We cover the common dual-clutch and automatic platforms: VAG DSG/S-tronic (DQ200, DQ250, DQ381, DQ500), ZF 8HP, and more. Engine + gearbox packages are the right way to deliver a consistent result to your customer.
What the file includes
- ✓Torque limiters raised to match engine stages
- ✓Faster shifts, firmer engagement, adapted shift points
- ✓Launch control RPM adjustable on supported TCUs
- ✓DSG/S-tronic, ZF 8HP and other common platforms
Frequently asked questions
When is a gearbox file necessary?
As soon as the engine torque exceeds the TCU's intervention thresholds, typically from Stage 2 on dual-clutch cars, sometimes already at Stage 1 on high-torque diesels.
Do you read the TCU through OBD?
Depends on the platform: some TCUs are OBD-flashable, others need bench or boot mode. Your tuning tool documentation lists the method; we accept reads from all major tools.
Will comfort in normal driving be preserved?
Yes. We sharpen the sport modes while keeping the comfort maps close to stock, so daily drivability is unaffected.
