How ECU file tuning works: bench files, analysis and tokens
Desktop ECU file tuning works on a dump — a copy of the data read out of the control unit, usually on the bench or via a supported tool. The software does not touch the car directly; it edits the file, and you write the result back with your own hardware.
Step 1: analysis
When you open a file in DaVinci Ghost, it is sent to the analysis engine, which identifies the ECU (brand, hardware and software) and returns the list of solutions available for that exact build. If the file cannot be read or has no solution, nothing is charged.
Step 2: apply
You enable the switches you need — see the full list on the Solutions section — and the engine applies them, correcting the checksum and CVN on save.
What a token pays for
One token is spent when the analysis confirms a file is tunable. Everything you then do to that file is included, and you can re-open and re-tune the same file for free. Tokens reset on a rolling 24-hour window. It is a per-file model, not per-switch.
Coverage spans dozens of brands and thousands of ECUs, cars, vans and heavy-duty trucks. Off-road only — for testing and educational use.
