    Eeprom checksum error.
    What is your ECU?
    Make virgin and adapt to car better than clone non working eeprom.

    If it is diesel marelli you have to make full bdm read(flash micro) and put it to donor ecu..

    ECU 8GMC.C1 So here eeprom near processor MPC5565, but here only setup, need to read eeprom from processor correct?
    Can I read eeprom from processor KTAG, then maybe any people can virgin it or I need to use Abrites? Thank YOU!

    Hello, I have same problem, I haven't swapped eeprom yet but I know that needs to be either clone or virginized by being read the whole flash, once I needed to program a ecu for a ram promaster, I tried with a used one but I couldn't make it work, I had to buy a new one, and at the time I load the calibration, serial number and security code was loaded from bcm. I think is the same system because both shows the same error "minikript not match"
    Did you find out how to make it work?
