Problem:
I have problem with opel delco e98. I write eeprom with foxflash. and after that ecu no communication.
Id make but can’t write backup. reading error wrong file dimension.
Solution:
Wrong file selected.
You read flash but write backup.
Select flash and write flash.
If still gives error when write flash, check wiring diagram and voltage. Turn on ignition switch, wait some minutes, try again.
