Gearbox tuning
A remapped engine makes more torque than the gearbox was set up for. Gearbox tuning matches it: clamping, shift speed and shift points.
What it changes
- Clamping Clutch pressure raised to hold the new torque.
- Faster shifts Sharper changes in sport and manual mode.
- Shift points Changes where the remapped engine makes its power.
- Launch and kick-down Launch control and kick-down set up for the car.
Why
Engine and gearbox, mapped together
On cars with DSG and other automatic gearboxes, the gearbox's own software limits what the engine can deliver.
Tuned together, the car pulls cleanly through every change.
On the day
How a remap at MMT goes
- 01 Book in Online, by WhatsApp or by phone. Tell us the car and what is on it.
- 02 Free health check Fault codes, boost, fuelling, the state of the car. We do not tune a sick engine.
- 03 Your map Written for your engine and hardware. We read and save the original first.
- 04 Checked Live data on the road: boost, fuelling and timing where they should be.
- 05 On the dyno, if you like Before and after runs on our rolling road, printout included.
- 06 Paperwork A receipt for the work and what was changed, every time.
Is a remap safe for my engine?
A remap written for your car, on a healthy engine, stays inside what the parts are built to take. That is why we check the car first (the health check is free) and why our software is developed on our own rolling road. We do not tune a car with a fault until the fault is fixed.
Will it affect my insurance or warranty?
Tell your insurer: a remap is a modification, and most insurers cover it once they know. A manufacturer warranty can refuse a claim on a part the remap could affect, so ask us before you book if your car is still under one.
Can it go back to standard?
Yes. We read and save the original file before we write anything, so the car can be put back to standard.
How long does it take?
Most Stage 1 remaps are done the same day. A dyno session, gearbox tuning or Stage 2 and 3 work take longer: we tell you when you book.
Do you remap at shows and events?
Yes, at many of the shows on our calendar. Message us before the day to check we can do your car there.
Can I pay monthly?
Finance options are available. Ask when you book and we will tell you what fits the work.
