PCM question.

[jmpSHO]

I pulled the computer out of my 95 ATX and I was expecting to see a sticker on it saying it was a D4U1. I pulled the PCM out of my 94 and it has the sticker. When I bought my SHO a long time ago the previous owner told me that it had a new computer in it and now I am wondering if it was the D4U1 PCM or a PCM from an older ATX SHO. Is there any way to match up other numbers on the PCM to see which PCM I have. I notice with the 94 PCM I have firmer shifts.

I believe the atx cars are as follows
93 had either h3z1 or h3z2 revisions
94 and 95 had d4u1

I don't think you really read my post because even though you posted some good info you didn't quite answer my question. I need to know if there are other numbers on the PCM to confirm it is a D4U1 PCM.

in that case no I don't know the answer to your question. I had a hard time following what is was you were trying to ask. Good luck finding your answer.
