Custom crank trigger wheel
 

I’m considering a custom crank trigger wheel … my first thought is an 8 tooth wheel for my AEM.

Could someone tell me the crank angle positions of the crank teeth (e.g. is it 10* and 80* BTDC, or 10* and 70*), and also the crank angle position range of the first edge and the last edges of the cam double pulse at the extremes of cam phasing?

I need to know because with the AEM, the significant edge (rising) of the cam pulse is not allowed to “cross over” any of the crank pulse rising edges. Thus the range of cam phase change limits the allowable number and location of crank teeth on a custom trigger wheel.
