I have a file from another programming software and want to suck it into EFI live. Problem is the segment ID for speedometer in the FILE does not match the PCM. All other segment ID's match exactly. This is because I took the car to the dealer to have the PCM reflashed mainly because I was unhappy and decided to retune the car myself using the lastes OS. Will I hurt the PCM if I download the old file using the old software to the PCM even though the speedometer seg ID is different?
