VRS pickup with only one lobe on the flywheel.
I don't use the Ecotrons ignition only the EFI side for fuel injection.
I am interested because Ecotrons changed my two stroke software so I could use VE and Alpha-N table. I have not tried it yet so not sure if I will actually still have 2T software or they have just activated it as 4T.
I use a wide band O2 sensor a lot on my 2T for tuning.
The brown line between the two white coursers shows the small injector going lean before the larger secondary injectors take over. Probably needs a bit of injection angle end adjustment.
A MAP measuring atmospheric pressure is pretty handy on a 2T for automatic RAD changes.
I am afraid I can't help much here as I only have experience with a single tooth wheel.
Yes, I too had to make diagrams to understand what was going on.
I think the "end of injection angle" is supposed to be degrees before TDC but I suspect it may be degrees before the actual ignition sensors trigger point.
Anyway "end of injection angle" is when the injection ends, it starts earlier and earlier (degrees wise) as fuel demand and/or rpm increases.
I found the best position was 180 or BDC where the pipe is supposed to be sucking the hardest. Others swear by ending the injection angle at transfer closing. Probably a mix of both is optimal.
