Yep I've seen that one but it applies mostly to non removable prom ones no?
Dont the proms have different sizes(or whatever the proper term is(like 4k 8k..or something)?
Can someone effectively take an 89 ECU and swap it into an 85? Since the 85 also is has a removable prom?
Do the functional differences effectively begin and end at the removable prom?
Are there any websites that have schematics and stuff?
Thanks,
