ct33dst : hi. So, need more information: - is the long-code string that you are attempting to load-back into the ECU legitimate?
- Where did you get the new long-code?.
- How did you lose the original long-code?
- How are you attempting the coding change - one byte at a time, or the complete long-code string in a single attempt?
I assume that you have ignition-ON, Engine-OFF Don
