1992 Saturn SC1 changing a computer out from another year

I would stick with the same yr and model ur 92 sl1 has throttle body injection one injector shooting down a throttle body. Ur 95sl1 has multiport fuel injection first yr for the sl1s to have it that's where each cyclinder has there own injector.U could try a pick apart or I don't think the new ones are that expensive they have to be programed though. The used one might have to be programed too depending on the option differnce and all that u would just have to see how it ran and if u were getting false codes. Good luck let me know how it goes.
