Does anyone know what year this eprom came out of?

I'm pretty sure the case is wrong, since the case says MD128625 which would have a different chip set.

Let me know ECU guru's!

That's what i'm thinking. But I swear when i took this ecu out and put in a 91+ ecu I had to switch over the 2 wires, it was so long ago I can't recall though.

I found a list, I think it's this one:
6/90-6/92 - Federal MT (MNGFL4M) - 1G DSM Turbo AWD (D27A) - MD166262 - E2T36578 - E931

What else besides the E931 makes you think it's that ECU? I can't find any markings besides the federal markings. If it's a 6/90 would it be a 90 ecu? or a 91?

I know for sure that the EPROM code for a 91-92 is E931. 90 ECU's are different. That's a '91 or a '92 ECU.

On a dsm, anything 6/90 or after would be considered a 91. June seems to be the start of a new year. With the info that Coltsfan found your ecu is a 91-92 like everyone else stated.

That 6578E on the plug matches the 6578 in the end of E2T36578. I have a pile of DSM ECUs and that number on the plug always appears in the end of that other number.

So yeah, we all agree. It's a 91/up ECU.
