Vehicle speed-limiter calibration — Cars / Vans
Changes a supported V-Max strategy after tyre, brake, drivetrain and legal requirements have been assessed. This product is prepared for Cars / Vans and is processed against the exact uploaded ECU or TCU file.
What the service includes
- speed-limiter source identification
- requested supported threshold calibration
- verification of related torque and diagnostic strategies
How the order is processed
- Upload the source file. Use the product form and provide complete vehicle, engine, ECU, read-tool and read-method information.
- Identification and verification. We check file integrity, ECU family, available SW/HW identifiers and compatibility with the requested service.
- File-specific work. Only the agreed function is processed. An ambiguous or unsupported variant is held for manual review instead of receiving an unrelated generic solution.
- Delivery and validation. The completed file is returned through the order workflow. Program it with suitable equipment, clear obsolete faults and validate the vehicle with diagnostics and logs.
Required information
Provide the current limit, requested limit, tyre speed rating and intended use.
Technical requirement: Always retain a verified backup of the original read. A partial, corrupt or incorrectly identified file may require a new read before processing.
Responsible use and limits: Removing or increasing a speed limit does not certify the vehicle for that speed. Legal and mechanical responsibility remains with the operator. The purchaser is responsible for the vehicle condition, lawful use, correct programming procedure and final validation.
Turnaround: Standard processing is normally completed within the service hours shown on the website when the file and technical information are complete. Unusual software variants or manual calibration may require additional confirmation.
