SCCA will allow us to do anything we want to the internals of the ecu. The housing and the stock wiring harness must remain unchanged. We are not allowed to add any wires or sensors that are used by the ecu. Basically what SCCA is saying is that you can chip your car.
The problem is that I can not find anyone that can chip / reprogram the early ecu's everyone seems to only be able to work with the 88 and up. So I was thinking. Could I get my SCCA IT car to run on an 88 ECU? I would just have to get it to fit in to the 85 ECU housing and make up some sort of jumper cable / ribbon cable inside the housing that would adapt the 88 ecu to the 85 wiring. I have been looking at the wiring diagrams for the two and it looks like it may be do able.
I am wondering has anyone done this? I am also looking for an ECU from and 88 with a "ge" motor.
I am also looking for a good clear wiring diagram for the 88 ecu. I have the one off this side but it is a bit blurry and hard to read. (Ya I am over 40 and the eyes are not what they once were) If anyone had a clear copy or could scan there manual and send me one I would appreciate It. I have the 85 factory shop manual so I have the wiring for the 85 ecu.
My plan would be to see if I could get the 88 ecu to work with the 85 car then I can get the 88 ecu reprogrammed / re flashed / chipped. I have been told that it is good for 10 hp on cars with free flowing intake and exhaust. Who knows if I get this to work we may be able to keep up with the Honda's
