Hey guys!



So ive made a bench harness for this 98 vortec PCM that im trying to reporgram. I got the OBD2 port wired in and all that but when I go to read the PCM with LS droid it says its locked? it says "failed to unlock PCM trying again in 3 seconds" is there a way around this or am I screwed and stuck with a GM PCM I bought.

please help


thanks
