you're correct, they are different, you need an ecu out of an '82 turbo, I don't think the ecu's between the different year turbo's will work (guys correct me if I'm wrong) the 81 turbo ecu will definitely not work...if your original ecu was in that bad of shape, an ecu swap might just fix your engine troubles...you might want to check ebay, or the parts and accessories for sale section of this site, if your junkyard hunting isn't turning anything up
on another note, I have the 82 fsm if you have any other questions you can email me them, it has some turbo stuff in it... (gonna be looking up your problem with the revs when I get home to see if there's any info)
good luck,
