Need to confirm I have a D4U1 PCM?

[jmpSHO]

I took the PCM out of 95 ATX and it didn't have a label on it. It did have a part number though, is there anyway to confirm that I have a D4U1 PCM?

yes you do!

all the 95 atx's come w/the D4U1 pcm's . IIRC all the 94's do too

The previous owner replaced the computer in my 95 ATX and I suspect that it may be from an earlier year ATX.

The only non-D4U1 ATX ECUs are the ones coming off a 93. the only way to verify is to check it out yourself. Hint: glovebox.

Does anybody read the first post of the thread before responding? Phoenix, I removed the PCM from my 95 ATX and it has no sticker or label saying it is a D4U1. So I then removed the PCM from my 94 ATX and it says very clearly that it is a D4U1 PCM. I ended up installing the PCM from my 94 ATX into my 95 ATX and I notice much firmer shifts. Now I either need another PCM for my 94 or I can just install the one I have but I want to confirm that it is a D4U1 PCM first.

all 94-95's have the DU41 the only one that doesn't is the 93's
