Tracy and Dale,

I think the light is on now.......I had it in my mind that the injectors were batch fired and

when Tracy and Ed said that the injectors were only pulsed once per eccentric shaft revolution

I still was thinking of all four injectors rather than two for each rotor !! DUH !!

Thanks guys

Kelly,

I think you just answered your own question. If you have four
injectors, only two are fired for any given intake cycle - the primary
and secondary for that one rotor. 180 degrees later, the other
primary and secondary pair are fired. Totally separate pulse
circuits.
