TuningSuite Terms of Use
Terms governing use of the TuningSuite portal, applications and services.
1. ECU/TCU files and authority
The customer confirms ownership of every submitted ECU/TCU file or full authority to have it processed. Files are processed only on the customer's instruction and for the selected services.
2. Emissions and lawful use
Emission-related solutions, including DPF, GPF, EGR, SCR and AdBlue changes, may constitute prohibited defeat devices. They are not intended for vehicles used on public roads and are supplied only for lawful off-road, research, export or competition use where expressly permitted. The customer is responsible for local law, type approval and roadworthiness.
3. Technical risk, checksum and writing
Controller modification can damage the ECU, engine, transmission or other components. The customer must keep a verified original backup, provide stable power and use compatible equipment. Unless a file is explicitly marked as corrected, checksum must be recalculated by a compatible flashing tool during writing. Automated matching does not replace review by a qualified tuner.
4. Liability, data and automated results
The operator is not responsible for damage caused by selecting the wrong file, unlawful use, an incorrect write procedure or incompatible equipment, except where liability cannot lawfully be limited. Match confidence, originality status and estimated power gains are technical results or estimates, not guarantees. Account data and files are used only to deliver and secure the service, process billing and provide support.
5. Acceptance and updates
Acceptance of the current Terms is required to create an account and use TuningSuite. Acceptance date, version, language and technical evidence are recorded. Material changes may require renewed acceptance.
