Use this bundle when a customer arrives with an uncertain ECU file, unknown tool read, DTC issue or compatibility question. It combines guided file review, tool-read checking and pre-order direction so the workshop can decide the correct service before committing to a full calibration.
What to send after purchase
- Original ECU or TCU read when available.
- Vehicle make, model, year, engine, gearbox and power.
- ECU/TCU label photos or software numbers if available.
- Tool used to read the file and the exact requested result.
For road vehicles, the workshop remains responsible for legality, diagnostics and safe use in its own country.
