PCM flashing question EFI live to HPT Quick question, I think.. Lol
My vehicle is currently tuned with EFI live, I was wondering if I would be able to edit the current tune and reflash with HP Tuners... 2002 C5 if it matters.

GM OS's have 8-digit id number starting with 1 (e.g. 12212156).
EFILive COS's have 8-digit id number starting with 0 (e.g. 02020005).
Not sure about HPT COS's.
