Guys 2 questions:, how much is the pulse light?

Also, it seems that the IP for the 606.910 has splined "outputs" ( sorry nomenclature escapes me). I ASSUME these splines are for "microtimng" each cylinder. If so, how does one do that? It seems your pulse method might be the only way, and then, at exactly which crank position?

I will learn how to tune this enigne! THNX!
