Modern dual-clutch and automatic gearboxes have their own control unit (TCU) with its own torque limits and shift strategy. After a Stage 2 or bigger engine remap, a standard TCU can limit torque, slip the clutches or shift at the wrong time. A gearbox remap raises the limits to suit your engine, and can sharpen shift speed, change shift points and improve throttle response in manual mode, depending on the gearbox.
We work on common gearboxes including VW Group DSG units and the ZF 8-speed automatic used by BMW and others. Send us your reg and we’ll confirm what’s possible on yours.
We check fluid condition, fault codes and clutch adaptation values before we change anything.
We read your TCU and plan the changes to match your engine map and power.
We set torque limits, shift timing and response for your car and how you drive it.
We check the changes on our 4WD dyno and on the road, then share the results.
The best results come when the engine and gearbox are mapped as one job. Because our Dyno Dynamics DS450 drives all four wheels, all-wheel-drive DSG cars such as the Golf R and Audi S3 can be tested under real load, so we can check that torque is delivered cleanly through the gearbox, not just on paper.

A gearbox remap is usually done with a Stage 2 or Stage 3 engine remap. Ask us for a price for your gearbox when you get in touch.
If your car is mapped to Stage 2 or beyond, or the gearbox is already limiting torque, a TCU remap is usually worth it. On a standard or Stage 1 car it’s often optional, and we’ll tell you honestly if you don’t need it.
See our Stage 2 remap, ECU remapping and performance tuning pages.
Often, yes. Many DSG and automatic gearboxes have torque limits that a Stage 2 engine map exceeds, which can cause slipping or limp mode. A TCU remap raises the limits to suit.

More torque always adds load. We set the limits to suit your engine power, not higher, and check clutch adaptation values first so we can flag any wear before we start.
Yes. We keep a copy of your original gearbox software and can put it back.
Yes. A gearbox remap is a modification, and you should tell your insurer.
