Interchanging ECM/ECU Part Numbers

I am currently in quite a dilemma. I have had my 93 3000GT VR4 for about 10 years. Just recently my ISC/IAC shorted out and burned up my ECM, literally... fire, smoke and all. I opened the module and the whole circuit board is torched. Unable to be repaired.
I have searched high and low throughout the US and no one has the exact part number I need. Junk yards, auto parts, remanufactures.
I am wondering if anyone knows if any other part numbers are interchangeable without having to reprogram? I'm looking for plug and play.
The module I pulled out is a MD190663 (E2T35691), I noticed that there is another module installed in the 93's that is a MD192589. Is it interchangeable? Or maybe the 90-92 module MD159966.

Any help would be a blessing...
