Support depends on the transmission, TCU type and software version, so compatibility is confirmed per file.
Typical Requests
- Raising TCU torque limits to match an engine calibration
- Shift point and shift speed adjustments, where supported
- Launch and kick-down behaviour, where supported
What To Send
- The original, unmodified TCU read
- The matching engine ECU file or details of the engine calibration
- Vehicle, gearbox type and TCU details
- Any clutch or hardware changes
Limitations
Not all transmissions or TCU software versions can be modified. Raising torque limits beyond the mechanical capacity of the gearbox or clutch can cause damage, so declare the hardware accurately.

Frequently Asked Questions
- Which gearboxes are supported?
- Supported automatic and dual-clutch transmissions, confirmed per file. Contact support with the gearbox and TCU details before ordering.
- Do I need a gearbox file with an engine tune?
- On some vehicles the TCU limits torque, so a gearbox file is needed for the engine calibration to deliver as intended. It depends on the vehicle.
