Problem:
BMW e82 1 series. Foxflash read edc17cp02 ok via obd,
Write tuned filed error
Write original file okay.
Is this a checksum issue?
Solution:
you need your tuned file without checksum correction. It will be do automatic.. We had a customer who had last week same Issue. Without checksum it will write.
Also not all edc17c06/CP02 can be done on obd.
Bench and all will be ok not checksum problem.
