So i need to replace the ECM on my 93 SL2 and everything I see says that it needs to be programmed before installing. I thought that these older computers had PROM chips and could not be programmed? Anyone have any insight on this?

I got a reman one. I plugged it in and so far everything seems fine. I need to replace my CEL bulb since it is blown so, I'm not sure if it is currently on. As for programming, would I need to do a passthru with the tech2 and the obd1 connector similar to the 96' and up?
Yes...and you may need to find someone that has the program. We used to have CD's with the calibrations on them. The new way is to download it through GM.
To be honest, I don't know if the downloaded version goes back that far with a saturn so I cannot tell to for certain that any GM dealer dealer could program it.
