And since the CAS is phased directly off the intake camshaft, there needs no other synching than to actually have the valve timing correct obviously not with the crank off either unless u like bent shit as the early DSMs do not use a crank sensor.
That said though, if the cam is off, I doubt it would show correct timing even through the ecm as it would force the CAS to fire at a different trigger point.
You need to make damn sure the actual component timing is correct. You then run a jumper to the unused plug off the firewall as illustrated, and hook up an inductive light and phase the CAS to 5 degrees BTDC with the car idling at 750rpm. If you have an idle issue, address that first if you can. A logger should show you where your timing is at I would think.
I agree that the mechanical end of things NEED to be set correctly.
All that i'm stating is that electronicly, his ignition map has set values of timing that area to be fired upon. The timing light needs to be used to verify that the car is actually firing when the software is telling it to fire.
Remember, this car isn't running on a stock map anymore, it should still be sitting at factory ignition settings (for idle) in the aftermarket map but thats not always the case.
no matter what the make/model/ems
