Xhorse Multi Prog new user review:
EDC16C34 PSA Group, Read ok, Write ok, IMMO OFF. First job with Multiprog OK.
For this ecu you need read external eeprom and modify literally 2 lines on the binary file. I’ve used a free tool for this, it’s called EDC16C34 IMMO OFF. It can read pin and disable immo on eeprom file. Just saved the new file, written back , Done! As far as I know for disabling immo you should always read the eeprom and modify it as the immo data is stored there.
FYI: the multi prog has a few immo off files. If you go into tools along the top to the drop downs and click on immo off, it’ll show the vehicles it can do.
