ECU Remapping

What is ECU remapping?

ECU remapping is the process of recalibrating your vehicle's Engine Control Unit (ECU) to optimize performance, torque, throttle response and efficiency while maintaining reliability. Every calibration is developed specifically for the vehicle and its engine configuration to ensure safe and consistent performance improvements.

Is ECU remapping safe?

Yes. Every calibration developed by Etuners is extensively tested to ensure safe operation when applied to a mechanically healthy vehicle. Professional ECU calibration always depends on the vehicle's mechanical condition and the quality of the tuning process.

Will ECU remapping increase fuel economy?

Under normal driving conditions, a properly calibrated ECU remap can improve fuel efficiency while also delivering increased performance. Professional ECU calibration is always tailored to the vehicle and driving conditions to achieve the best balance between performance and efficiency.

Can my vehicle be restored to stock?

Yes. Your vehicle can be returned to its original factory software whenever required. The original factory software is safely retained, allowing the vehicle to be restored whenever needed.

Which vehicles are supported?

Etuners develops ECU remapping solutions for a wide range of petrol and diesel vehicles from most major manufacturers. Our custom ECU remapping solutions are developed for each supported vehicle to ensure optimal performance, reliability and everyday drivability.

Gearbox (TCU) Tuning

What is gearbox remapping?

Gearbox remapping, also known as TCU tuning, is the process of recalibrating your vehicle's Transmission Control Unit (TCU) to optimize gear shifts, transmission response and overall driving performance. Every calibration is tailored to the specific transmission, ensuring smooth operation and reliable performance.

Is gearbox remapping safe?

Yes. Every TCU calibration developed by Etuners is extensively tested to ensure reliable operation when installed on a mechanically healthy transmission. Professional transmission calibration always depends on the gearbox's mechanical condition and the quality of the tuning process.

What are the benefits of TCU tuning?

TCU tuning can provide faster gear changes, improved launch performance, smoother shifting and better transmission behavior under different driving conditions. It can also improve driving comfort and optimize the transmission's response during everyday and performance driving.

Can the gearbox software be restored to stock?

Yes. The original transmission software can be restored whenever required. This allows the vehicle to be returned to its factory transmission calibration at any time.

Which gearboxes are supported?

Etuners develops gearbox remapping and TCU tuning solutions for a wide range of DSG, DCT and automatic transmissions from most major vehicle manufacturers. Our transmission software is developed for a broad range of modern automatic gearbox platforms.

General

How long does a tune take?

A typical ECU or TCU calibration is completed within a day, including a full vehicle health check, data logging and road or dyno verification. Complex custom projects may take longer — we'll always give you a clear timeframe up front.

Do you tune my make and model?

We specialise in European platforms and twin-clutch transmissions, but support a wide range of makes and models. Contact us with your vehicle details and we'll confirm what's possible.

Will tuning void my warranty?

Modifying factory software can affect your manufacturer's warranty. We're happy to discuss the implications for your specific vehicle before any work is carried out.
