TCU Tuning (Transmission Control Unit)

Vehicles equipped with automatic transmissions are normally fitted with a TCU (Transmission Control Unit), which controls all aspects of the transmission's functionality, including gear shifts and torque limitation.

Performance from Alignment

The TCU works in harmony with the ECU (Engine Control Unit) by sending and receiving real-time data across the vehicle's network system.

When tuning a vehicle, it is often recommended that the ECU and TCU be remapped simultaneously. This ensures both control units continue to work in harmony, fully optimising the vehicle's performance and drivability.

At Eurotech Autohaus, we specialise in TCU tuning and remapping. A TCU tune enhances your vehicle's performance and drivability by optimising the TCU, which manages the vehicle's power delivery, stability, and traction.


Why Get TCU Tuning?

  • Improved Shift Performance: Increasing the speed at which the gearbox changes gear for smoother, quicker response and better acceleration.
  • Enhanced Responsiveness: Adjusting shift firmness and timing to make your vehicle more agile and engaging.
  • Torque Limiters: Raising TCU torque limiters to prevent the transmission from limiting engine performance.
  • Hydraulic Pressure: Increasing hydraulic pressure to boost clutch clamping, preventing slip in highly tuned vehicles.
  • Move Shift Points: Adjusting RPM limits to optimise performance.
  • Advanced Options: Activating features like launch control, full manual mode, and deleting kickdown for enhanced driving dynamics.
  • Adaptation to Modifications: Recalibrating the transmission to work optimally with modifications like turbochargers, superchargers, or larger-diameter wheels, maximising performance and drivability.
  • Optimised Towing Performance: Improving the transmission's ability to handle heavy loads when towing, providing better control and reducing wear and tear on drivetrain components.
  • Extended Transmission Life: Optimising shift points and reducing stress on transmission components, leading to fewer instances of premature wear and tear, potentially saving on costly repairs or replacements in the long run.

Our TCU Tuning Process

1) Diagnosis and Analysis:

We connect specialised equipment to your vehicle's diagnostic port to access and analyse the existing TCU software.

2) Custom Remapping:

Based on the analysis, our skilled technicians modify the TCU parameters to improve gear shifts, reduce lag, and enhance overall traction control.

3) Testing and Validation:

After remapping, we conduct thorough testing to ensure the modifications deliver the desired performance improvements without compromising safety or reliability.
