Will a Evo 1-3 ecu work on a 1G?

not sure..but do remember. 90's had a differant harness then 91-94

may fit one, but not the other..

If you got it together with harness, it would. The socket is different than a 1G so an adapter harness would be required otherwise. Might as well jump straight to the Evo 8 ecu if you consider making an adapter harness.

Here's a couple link to the pinout of the Evo I-III Ecu harness Pin out PDF and the Pin out to the later Evo-IV-VIII Here

Also there are differences between the USDM evo 8 and the EDM 8(260)
Here is the USDM Evo VIII pin out

If this is something you plan on doing...

not worth it. just stay 1g eprom.
But if you really want to try it I have a few spare evo 3 engine harness laying around
