Professional ECU/TCU calibration service — Cars / Vans
Provides controlled file-specific work for the selected function after ECU identification and compatibility review. This product is prepared for Cars / Vans and is processed against the exact uploaded ECU or TCU file.
What the service includes
- binary and ECU identification
- targeted modification of the agreed function only
- integrity, checksum and request-scope verification
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 original read, vehicle/engine/ECU data, read method, all relevant DTCs and clear special instructions.
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: Availability depends on the exact ECU and software. Mechanical diagnosis, correct programming and legal compliance remain the customer’s responsibility. 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.
