36-1 crank wheel setup in VEMSTune

[qwkswede]

Hello, I'm new here and new to VEMS. I have alot of Megasquirt and other tuning experience, and I'm trying to apply the knowledge here. Its tricky sometimes.

The engine is an inline 4 cylinder Volvo.
I have a 36-1 wheel on the crankshaft with a hall sensor that aligns with tooth #9 when at TDC on cyl. 1.
My thoughts are, trigger on tooth 3, its 60 deg. btdc (so counting from zero, that is tooth 2)
Then the next trigger should be 18 teeth later at tooth 20?
It looks like this:

Next tooth is relative to the first, so its 18
