I re-install stock injectors, stock O2 sensors, hotter BKR5E spark plugs, EGR, set to stock fuel pressure, advance exhaust cam, retard intake cam, as well as give the stock ECU control of injectors, ignition, and IAC. I run a cat year round, so that isn't a problem. Since I'm 1995, I have to pass a rolling dyno test. I think if you can pass that, you can pass the OBD2 test. I've failed enough to know exactly what it takes (for my engine anyways). By now, I have set up the MS harness with stock connectors for injector harness, ignition, and IAC so that switching control from stock to MS is "plug and play".

Thanks for the tips... I know this is a delayed response but the car sat for the winter and I am back at it now...

I left all of the stock EXU plugs in the engine bay in case I needed to switch back... The only one I messed with that will be very difficult to get back to stock plug (I snipped the wires because I only had one plug) is the IAC... Do you think I will
need the stock ECU to control it for emissions?

Thanks again.
