In the middle of selling an ECU-less car!
Either the buyer didn't ship me a stock one or the post office is slow... hoping for the latter, but I may go junk yard shopping tomorrow regardless.
Will a 90-93 ECU work in a 94?

I've tried the search, but have only found that a '94 ECU works in a 90-93. I have a '94 Q, hoping all OBD1's work in it to make it easier to find one.

You are right, pardon my ignorance... I just talked to Wes the other day about ECU's. Been a long week already and I'm about to be up late tonight working! 
at least I work from home though

Search n00b!!!!! 
In case anyone comes across this again, all 90-95 ECU's are interchangeable. If your car has TCS, then you want to be sure to get a TCS ECU. IF your car doesn't have TCS, then you can get either a TCS or non TCS ECU, however if it is a TCS ECU then your ECU will throw a code for the secondary TPS, but you won't get a CEL so it's not a real huge deal, IMO.
