I'm not sure about the output firing order. We're using 6 double ended coils. I thought we had a sequential setup with the multiplexer, but with the new layout, we'll be using wasted spark- I think.

The specs for the R500 show a higher output than the M&K Pro-14 CDI I'm using. Mine seems to be running fine at 1 bar with the CDI driving all 6 waste spark coils. I guess it would be better to have 2 CDI's, but in case that doesn't work, you have a fall back plan.

I prefer to make a one line drawing of the wiring to make sure it's all good.

I just draw the lines between the plug on the ECU and the CDI noting each connection number. Then from the CDI and the coils with the multiplexer thrown in where it goes. That way I have a good graphical representation of where everything is. I don't think too well in space, I have to see it.

It's running on all six cylinders! Huge thanks to Geoffrey- your recommendation turned my project around.

Now we will get the I/C and intake plumbing finished and I could be breaking the car in by Friday.

YEEE HAAAAWWWW!
