thats what i thought, but what i have downloaded of the GM ECM site listed it as a different number, i'm just assuming its the same ECM with a different P/N.

whatever the upgraded '7730 ECM's number is, some 94 3.1 Cavaliers got it.

same situation as above...

if someone can get me the exact number used, then i'll add it in.

but they are interchangeable, thats the biggest thing.

The '7730 ECM is now 88999196, According to Delco, and the 94 Cavaliers got ECM number 88999192. The last number is still the current number for the ECM for a 94.

It's ok, I don't mind. My source for the part numbers was/is FMP (Factory Motor Parts). Around here they supply auto dealers and independent shops with parts, and I happen to have an account with them through my work. They are usally cheaper than gmpartsdirect.

i'll add it in as soon as i'm not busy.

That has got to be a nice hookup.
