Original ECU files (original files)

One Original file (Original File) is the unchanged, factory software and calibration file of a control unit – without chip tuning, immo-OFF or other processing. We provide it when a defective control unit has to be replaced, a clone programmed or a processed control unit reset to the factory state.

With original files stored via 800, this is the largest stock in our catalogue, and the files are aimed at workshops and vehicle owners who need a matching original file for replacement control units, clone programming or retrofitting.
