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.
