Gearbox
Tuning
A tuned engine makes more torque than the factory gearbox software expects. A TCU tune raises those limits and sharpens every shift, so the gearbox keeps up instead of holding the car back.
Faster shifts
Quicker, firmer changes when you're pushing — smooth when you're not.
Torque limits
Raised to match your engine tune so the gearbox stops cutting power.
Launch control
Higher launch RPM and cleaner launches where the platform allows.
Better daily feel
Less hunting for gears and more sensible kick-down behaviour.
The Process
How a gearbox tune works
- 01
Health check
We check fluid condition, clutch wear data and adaptation values before touching the software.
- 02
Read & calibrate
The TCU is read and calibrated to suit your engine tune, power level and how you drive.
- 03
Road test & adapt
We road-test, reset adaptations where needed and confirm shift quality before handover.
