XFi 89-94 ecms, oem part numbers ?

I'm desperately trying to find a used ECM for a 1994 Metro XFi.

What was the OEM part numbers for these ECMs build for 89-94's ?
what was the E code on the outside of it ? It was different then the base and LSI's.

if you look on your ecm there will be 2 or 3 big letters, thats the code you need to match. once you find that post it here and someone may have a used one
