I am try to flash a 04 Colorado I5, I was able to read and save the stock file, I made my changes and tried to re-write it and it keeps failing, it throws up this code Unknown error 8A, I have tried unplugging all other devices, ie.. aftermarket tuner, we disconnected the battery and reconnected it. clean the cables . Any suggestions ???
Could be a battery issue.
It doesn't have to be perfect, it just needs to be done in two weeks...
A wise man once said "google it"
please email the file to support, this error could indicate the calibration is corrupt or incorrectly modified.
