I looked at it today and it ran like a bucket of shit and behaved like it was cross firing.
Big internal clangs as you could see the engine momentarily reverse direction when running. I started disconnection the leads and found it ran best on one coil. One of them had no spark until a certain rpm.
So I replaced the coil, still same, replaced the DFI still same. So I thought maybe the ECU commanding odd timing? disconnected the ECU, so in the end only CAS and new coils and DFI were in the system.
Check this high speed video.
So it seems it has moved the firing of one coil and superimposed it on another making that one fire twice.
Runs on the left coil only. The other working coil plugged up it kicks the engine violently in reverse. Interestingly when it gets to high enough revs the firing moves back to the middle coil and especially on decel. So when the leads are connected the engine suddenly comes to life at that rpm.
As everything is eliminated this can only be CAS related. Anyone seen something like this before?
