Any update with this issue?

For your customers that swapping the ECU fixed the problem what issues were they having? Similar?

No, I don't know anyone that I can borrow ECU from. Not sure why it would be the ECU it works flawless with the distributor/plug wire for 2 years. What would be bad with ECU that would work great with distributor but not with COP? I will buy one from you and try it, if it does not fix the problem le...

So finally got COP to work. Took buying 3 good used distributors what worked great but not with COP then as a last ditch effort bought a OEM néw one.....it worked. Progress has been made but now I have random misfires/stumbles. My commute is 26 miles and some days it happens on and off the entire wa...

Working on trying to find an different ECU to test but until then maybe I can test a few other ideas? What would you have me do after i tested a different ECU and still had same issue? What would cause such a weak spark with coils? Power to coils? Output from CRP box? Power into CPR box? Same amount...

Does this have an OEM engine harness?

Any options other than another ECU since I do not have another one to try?

P28 ECU with S300V3. Plugs are BKR8EIX with .025" gap now. Going to re-gap to .020" once boost is turned up past the 3psi we have it set to now.

I have also noticed the spark generated by the coils is very weak compared to the spark generated by the dizzy/plug wires.

OEM harness and resistor plugs

I will try to find another ECU to try. I don't understand though how a ECU can work fine with every setup but the CPR? Are there certain ECU's or certain things about specific ECU's that don't allow the CPR to function correctly?

Setup - CPR installed on fully built B18C1 in a 96 civic sedan. K20 coils, S300V3 Issues - Car is very very hard to start and back fires like crazy while trying to start. It will stumble and fire up but only after cranking and cranking. Sometimes it wont start at all just back fires. Once car starts...
