Newbie to using EFI live for anything, can anybody direct me to someone capable of removing or altering a couple ECMs? One is just a GM 5.3L For the Passlock goodness. The other is a p0017 on a Colorado. Hoping timing advance acceptable range can be opened up enough to keep code off? It's my personal truck and runs great and is quite timing chain wise. I searched for said code and nothing came up. Thanks a bunch!
