1988 SC... uncommon ECM?
I guess the subject gives it away, i was looking around on Tuner Cat and didn't seen an ECM part # listed for my car, and i thought i'd heard before that somewhere that the 88 TBI car has some oddball ECM that nobody really works with.
Now, if someday i get into chip tuning (I know theres some real good reasons too, but its my only car and i don't have the time to get really into this tuning thing much right now, don't have enough mods yet to really need it anyway) would i need a different ECM altogether? I have the "box" out of an 89 RS, would this just plug in and work? Thanks for any input, i'm trying not to ask stupid questions.

Next up: headers and gears

Yes you can directly plug in another ECM. Specifically the 8746 and the 7747. These are supported by Tunercat.
Yes the 88 TBI ECM is an oddball and not easily reprogrammed.
Do a search on 8063, 8746 and 747 to find a bunch of good info on this topic.

You would be best served by getting the slightly newer one or a 747.
The 747 is totally hac'd so you can change about anything, tune wise, and there are some neat patches for it.

Well, i just went out to the garage and looked at that spare ECM i have, and its an 8746 which there seems to be lots of info on. Its out of my freinds car that had the same exact powertrain as mine, its just a year newer, so it should just "plug in" like you said, right? It'll be a while probably before i have the time/money to get into tuning, not to mention i'm quite a few mods away from needing it, but i appreciate your help thanx guys!
