TCU & GEARBOX
REMAPPING
Specialist gearbox calibration designed to improve shift behaviour, response and the way your transmission delivers performance.
ENGINE POWER
NEEDS THE GEARBOX.
Your engine might be making more power, but the transmission controls how that power gets to the road.
A TCU calibration changes the way the transmission operates, including supported shift strategies, torque management, shift behaviour and other transmission parameters.
TCU tuning can be particularly useful alongside an ECU remap, allowing the engine and transmission calibrations to work together rather than treating them as completely separate systems.
Optimise supported shift behaviour and transmission response.
Adjust supported torque strategies to complement the vehicle’s calibration.
Tailor the transmission behaviour around how you use the vehicle.
TCU
STAGES
The available calibration depends on the transmission, software and vehicle. We’ll establish the appropriate option before carrying out the work.
STAGE 1
A transmission calibration focused on improving shift behaviour, response and overall drivability.
- Improved shift response
- Optimised shift behaviour
- Torque strategy adjustments
- Designed around the vehicle
STAGE 2
A more performance-focused calibration for suitable vehicles and transmissions.
- More aggressive shift strategy
- Increased transmission response
- Advanced torque strategy
- Vehicle-specific setup
CUSTOM
Specialist transmission requirements can be discussed where a standard TCU calibration isn’t appropriate.
- Modified vehicles
- Specialist applications
- Individual requirements
- Advanced transmission projects
WHAT CAN
CHANGE?
SHIFT SPEED
Supported transmission parameters can be adjusted to alter the speed and character of gear changes.
SHIFT POINTS
Shift strategies can be tailored where the transmission software provides the appropriate control.
TORQUE LIMITS
Supported torque management strategies can be calibrated to work alongside an ECU tune.
DRIVING CHARACTER
Transmission behaviour can be tailored towards smoother daily driving or a more performance-focused setup.
MAKE THE
POWERTRAIN WORK TOGETHER.
When an engine is tuned, the transmission still has its own torque management and shift strategies. On suitable vehicles, combining ECU and TCU calibration can help the two systems work together more effectively.

GEARBOX TUNING
DONE PROPERLY.
IDENTIFY THE TRANSMISSION
We establish the vehicle, gearbox, TCU and software details before confirming which calibration options are available.
CHECK THE VEHICLE
Relevant diagnostic systems are checked to identify existing faults or transmission-related issues before calibration.
APPLY THE CALIBRATION
The appropriate TCU calibration is applied using suitable programming equipment for the vehicle and transmission.
VERIFY OPERATION
The vehicle is checked following the work and relevant systems are reviewed to confirm correct operation.
DIFFERENT GEARBOXES.
DIFFERENT APPROACHES.
Automatic transmissions vary considerably between vehicles. The available calibration and the way it should be approached depends on the transmission and its software.
Traditional torque-converter automatic transmissions.
Dual-clutch transmissions and performance applications.
Supported Volkswagen Group dual-clutch applications.
Supported ZF automatic transmission applications.
EVERY TRANSMISSION IS DIFFERENT.
TCU calibration availability depends on the vehicle, transmission, software and hardware. Not every gearbox supports the same changes or the same stages. We’ll establish what is available for your vehicle before carrying out the work.

FAQ
WHAT DOES A TCU REMAP DO? +
A TCU remap changes supported transmission calibration parameters to alter things such as shift behaviour, response and torque management.
DO I NEED A TCU REMAP WITH A ECU REMAP? +
Not necessarily. However, on suitable vehicles a TCU calibration can complement an ECU remap by adjusting transmission strategies to work alongside the engine calibration.
WILL A TCU REMAP MAKE MY GEARBOX SHIFT FASTER? +
On supported transmissions, calibration changes can alter shift behaviour and response. The exact changes available depend on the gearbox and software.
CAN YOU TUNE DSG OR DCT GEARBOXES? +
Supported DSG and DCT applications can be considered. Availability depends on the exact vehicle, transmission and software.
CAN YOU TUNE AUTOMATIC GEARBOXES? +
Yes, supported automatic transmission applications can be considered. We’ll identify the transmission and available calibration before proceeding.
HOW MUCH DOES A TCU REMMAPING COST? +
TCU Stage 1 starts from £149 and TCU Stage 2 from £250. Final suitability and pricing depend on the vehicle and transmission.
