Default I have the wrong PCM

I bought this Lt1 not knowing much about the engine and got the computer with it.
I just realized it has J on it, being for a Zr-1 LT5.

I already sent this into LT1wiring to modify the harness and program PCM. He didnt say anything about it.

Being that I have an Lt1 motor with a Lt5 PCM. Any chance that it could still work???

Im thinking... do the PCM's look the same for lt5 and lt1? Mine is a 95. The lt1 wiring harness hooks up fine

The LT5's ECM doesn't look like your 95's.

OK should be good then id think. IT hooks up fine. But this sticker on the computer had J on it so thinking it had to do with ID-ing the engine it was with. WELL THX!
