Hi friends,
I want to map a motronic M1.3 ecu (Peugeot 405 1,9L 120 bhp).
Can anybody help me with checksum-correction for this ecu?
Can I run a checksum 8 bit over the hole file (original) and than over the mod map and than I only change on the lot "FF" bins, so that the original checksum will fit?
Does anybody know more about the old motronic checksum-algorithm?
kind regards
Paul

Yes you want to in effect balance out or figure out the algorithym for the file checksum is not needed to make car run though for that ecu
