checksum correction? please?

Postby bradley » Tue Sep 28, 2021 6:56 pm

hi can someone please do a checksum correction for me?

I have tried through winols but it just will not let me

i don't fully know what i am doing with it so likely my fault, old ecu is water damaged got new one, read and wrote micro on it but IMMO is causing an issue

have done a read via obd, hopefully it worked

First if yoy want to clone this ecu you need to reflash full flash + eeprom, After that you need to sync CAS with ECU to start.
Yesterday i write same ecu,
OBD Read is ok, but partial write of mod. kills it.
After read on bench and write of full checksummed file everything is ok. ;)

Plus your reading is bad! Nothing to checksum.
