Hi there, while I was writing a Re mapped file, onto the ecu, via Obd.
Write failed.
Car won't start.
I'm not having any success in putting it right again.
Can anyone help me out, Please.
I have read via kess boot, and Ktag boot mode, and have the original and modified files.
What is best cause of action?
I'm not a file modifier, so I'm struggling now.
Tia.

If you have read ECU with Ktag before you write it with KESS you can write backup.
