MEDC17 / EDC17 Editor — immobiliser data, transfer, clone, Immo OFF

Universal editor for Bosch MEDC17/EDC17 ECUs. Upload the internal flash and EEPROM dump: the service detects the immobiliser type (immo 4, immo 4 old, immo 5, immo 5+, immo 6), decrypts the immobiliser block and shows editable fields — VIN, immo ID, CS (crypto key), MAC, PIN, FAZIT, ECU status and PowerClass.

Change only what you need: the rest is kept, block checksums (CRC16/CRC32) are recalculated and the edit goes into the last mirrored immo block. With status Immo OFF the immobiliser is cleared in the EEPROM and, where the type requires it, in the flash too — the result comes as one archive with both files.
