The rear end ratio is stored in the tcu. And 96' DAS is married to the ecu. It is very different than the 97' up stuff in what is going on but it is more than starter interupt. But isn't the car being talked about a 92' So it is really just the ecu, and it needs some other stuff but it is analog. They need wheel speed from ABS and if it is an ASR car you can just dump that and get an ecu without ASR. IF you want other stuff to work like ISC then you would need that module but I think you could put a standard throttle body on it and it would work just fine. IT is simple enough to test this out.
