Hmm, my injectors had different colored control wires, so I assumed they fired when the intake valve was open. So the *2 was really *4 injectors/2 revolutions.

resistor is on the guino, will likely stay there.

I'm just guessing on the saturn value. You posted a 267,857,142.86 figure for the 21lb injectors and that was close enough to my guesstimates that I went with it. But if we really do have variable fuel pressure then we can only make a guess on the flow and try and true it up on fillup.

Anyway, maybe your mpfi squirts two cylinders at a time and mine just one? Is there a saturn expert in the house?
