Everything went fine, truck battery was on a charger. Laptop Battery was on a charger. Made it to 74.2% and it stopped loading and said "Writer Transfer Request: Timed Out".
Low Engine Oil, Engine Over-temp, and other warnings popped up on the dash and the truck will not start.
Every time I try to "write entire" now, the exact same thing happens. makes it to 74.2% and then times out.
Does anyone have any suggestions on how to get the ECU recovered or get it to accept a tune file?
I have read that ford ECUs are very difficult to brick unrecoverable, but I have not seen any methods for recovering them.
Thanks in advance.
