What is the process after purchasing an ECU tuning service?

After completing your purchase, please carefully remove and securely package your original engine control unit (ECU). If you experience any difficulties removing the ECU from your motorcycle, contact us — we can also carry out the removal and installation directly at our facility. You can download and print the shipping label to our address from the download section. Please insure your package for the appropriate value and obtain a tracking number. Additionally, print the order form and include your contact details along with any specific requests or important notes in the designated fields. A

Does modifying the ECU affect my manufacturer warranty or road legality?

Yes. Any intervention in the engine control unit will void the manufacturer’s warranty as well as the vehicle’s road approval. The extent of the modification does not matter — even a single altered bit can be sufficient for the manufacturer to deny warranty claims. All products offered are strictly 100% RACE USE ONLY and intended exclusively for competition use on closed racing circuits, even if not explicitly stated otherwise. Use at your own risk. It is the vehicle owner’s responsibility to ensure compliance with applicable laws and to understand the potential impact on warranty coverage bef

Is quickshifter programming harmful to my gearbox?

No — when properly calibrated, a quickshifter does not cause premature or increased wear on the gearbox. With correctly adjusted shift times and activation thresholds, gear changes occur smoothly and under controlled load conditions, ensuring reliable and clean operation. Professional calibration is essential to guarantee optimal function and drivetrain protection. If you ever feel that the shifting behavior is not as smooth as expected, simply get in touch with us. We will gladly review the setup and ensure everything performs as intended.
