I converted my car a while ago to cops with megasquirt and now i need to go back to stock ecu and coils for california smog. My OBD fail and MS are not getting along :( . I lost the oem connectors for the stock coils but have some contacts that fit on the coils pins. I just need to know which pin is what now. Here is a pic and hopefully someone knows which pin goes to which wire.

Umm.. won't the stock ECU run your COP's? I was under the impression if you wired them for wasted spark like stock it would run just fine. Or is it an emissions requirement?

It will but the dwell settings are different. Technically you can run it. There is a chance of frying the coils though. Guys do run them without a dwell reducing circuit.

+1 on the dwell. I didn't feel like risking it. Thank you for the quick reply. The car is up an running on the stock ecu and coils.

No problem. Good luck. I gave up on trying to battle passing CT emissions with a parallel setup so I went back to stock ECU as well. I kept getting a CEL because the AFR's were too far away from what the stock ecu wanted to see.

I passed in about 10 minutes after using the proper driving cycle. You dont need to drive 100+ miles or w/e you just need to clear all the readyness codes. Search my old posts and you might find a thread or 2 about what info i followed to pass.
