I've searched for hours.

I took the PCM out of my 1999 corvette along with the V1 interface that was licensed to it, and installed it into a 1980 Corvette with an LQ4

now when I try to load a tune, or read the current tune, I get a message thet the PCM is locked. I've tried using the EFI live to unlock it, to no avail.

Any suggestions?

Thank you

PCM. Dang auto correct.

Oh well. I'm sure y'all knew what I meant.

and your sure you didn't lock it with a custom key?

Yeh. Positive I didn't lock it intentionally.

I've heard that a low battery, either in the car, or the PC, can trigger the PCM to lock on it's own. Is this correct? I've also read on these forums that it could be a glitch in the EFI software. Is this also a possibility? That would suck if true.
