It is being used on a 1040 ems box with all 4 coil outputs,on a turbo app.
The car starts and runs,but we can't sinc the timing,it jumps from tdc to 180 and back and forth,it doesnt even clean rev.i have tried multi spark and then tried waste spark and does the same,when i just use one output and one coil it works fine...
using honda cycle coils c.o.p. setup.
the wiring is by the book and used dwell settings that aem tech gave us.
do i need to use sheilded wiring?,could the signal be jumping in the harness?

please help 2 days now and i'm baffled.

I was told not to go by the wiring diagram in the manuel for it has a firingorder of 1 2 3 4 and i need to wire it up to fire 1 3 4 2 can anyone confirm this,or have another diagram that i can go by

just for the wiring that came with the c2di for direct fire on a 4 cyclinder. that make the correct changes in the aem software. I've been running this on my car for over 1 year and I have not had any problems. I've setup a few other cars for wasted spark and direct fire, never had a problem. what are the dip stickes set to on the c2di? did you want the correct changes in the aem software? the chanes you make in the software is was dictates the firing order, no how you wiring the coils up.
