Edge = rising

Type = multitooth

Filtering = Disabled

TDC after the trigger (vr sensor) deg =??

I while fine adjust with light pistol later
  • Untill someone smarter pipes up, this is how I understand it. What this is asking for is once your trigger tooth (in your case, first one after missing tooth) passes the vr sensor, how far does it have to travel before #1 is at TDC. If your diagram below is right, I would set it at 90 degrees.

Number of teeth on the wheel = 35

36-1

Trigger tooth = 1

Number one tooth after the missing one

Next Trigger tooth = 18

Crank min period usec = 3000 (assuming a 4cyl that is 6000usec for a whole crank rotation, which is 10000 RPM), but set it lower to be sure.


360/36=10

With this non-standard missing-tooth shape, the signal will be bigger aroudn the missing tooth, and R181 (factory-installed on v3.3 ; needs a small and clean tracecut surgery before v3.3) becomes important (min 100k, maybe 180k or higher). See InputTrigger/RunOut

It's very annoying if the system is near the operation edge, and sometime loses track. In any case, watch wheel-error (mlp01 first line) in case of any hazard.
