HOW IT WORKS

Start with the vehicle. Then submit the file.

Chiptuning is not a one-size-fits-all process. ECU and TCU files differ by vehicle, control unit, software version and application. The correct workflow begins by identifying the vehicle category and submitting the original file for review.

VM DIAG supports a broad range of vehicle environments and provides file-based technical services according to the supported control unit and requested application.

Vehicle Identification Category, model and control-unit information matter.

Original File Submit the source file before any calibration work begins.

Technical Review Compatibility and requested service are checked first.

Controlled Delivery Prepared file returned according to the confirmed workflow.
