FAQ

What are the benefits of ECU tuning?

Simply put — it makes your car faster.

Improved throttle response and unlocked torque limits deliver a driving experience beyond factory settings.

Will fuel economy improve or get worse?

It depends on the vehicle. Smaller-displacement cars often see improved fuel economy, and optimizing ECU parameters can also lead to increased peak output.

Will my dealer/seller warranty be affected? Can the data be reset or erased?

Please check with your dealer or retailer regarding warranty coverage.

Data will not be erased by a diagnostic reset at a regular workshop. However, data may be lost during ECU/TCU firmware updates.

Is there a dealer near me? Can you service my vehicle if I’m far away?
