I'm getting a 92 del sol from a friend, the ecu was fried but he replaced it. It's not working still, but he hasn't flashed it to the new car yet. Here's the thing, he doesn't know how, I'm a little confused on how to do it (neither of us have done it before) and the mechanic is insisting they can't do it on a used ecu, that it has to be brand new. So, I know a used can be flashed, but I don't know where to find the proper software and equipment for a 92 del sol. Does anyone know? Thanks!
