 That's correct.  The EC2 fires once per e shaft revolution and the pulse width timing of the injectors is varied based primarily on the manifold pressure sensed.

Al,Rusty and All,
Excuse my ignorance here, I have absolutely no knowledge about how ECU's work. I've heard people say that it reads MAP settings - so what is a MAP, and if it's different because the pressure is different at different places in the inlet, how can the computer calculate the inlet charge and timing.
I'm confused!

It is my understanding that the EC2 does not adjust timing but the injectors pulse width only. Is this correct?
