What year is the donor cars ecu and the car its going into? They should be swap able without any issues as long as they are both 95-96 or both 97-98. I am assuming they are both early models if they are eproms.
I have a 2g ecu for sale over in the classifieds if you wanted to try it out before you buy something and it doesn't work. I am about an hour away or so. lmk
