from my experience with the quad cam avcs, full throttle pull, exhaust cam will sit around 25-30deg.
when adam says the thing is rich, .65 is way to rich and I bet is causing misfire. These engines work better around .78-.8 lambda.
We are expecting the falling edge on cam teeth to be just to the left of the "gaps" on the crank. Then as the cams advance that cam edge moves further to the left of the gap.
Since his signal is inverted his falling edge actually starts off on the right hand side of the gap, and as the cam advances it crosses over to the other side of that gap. I would say this is when it gets all upset. Changing to the rising edge will put the trigger points back to the correct side of the gap where we designed them to work.
A bit of rounding at the top or bottom a square wave is usually not a drama, the actual trigger point that the ecu uses is at a level of about 1.0 or 1.5V depending or if its rising or falling (cant remember which is which). So provided the edge looks relatively vertical around the 1.0V mark you are usually good.
Andpdas, I should have also mentioned if you change the edge to rising and the engine will no longer start you may have to try adding or subtracting 360deg from your current trigger offset.
