i always do a full bdm clone.
I did today 2 SIMOS 6.22 ECUs by BDM-100 The trouble was that EEPROM chip M95320W was not reading correctly, even though no indication of trouble and/or errors. I had manually dumped both chips for comparison purposes. Secondly, BDM-100 does not recognize this ECU and you're limited by only FULL read/write. Any comments, suggestions, remedies will be much appreciated.
