 That's correct.  The EC2 fires once = per e shaft=20 revolution and the pulse width timing of the injectors is varied based = primarily=20 on the manifold pressure sensed.

Al,Rusty and All,

I've heard people say that it reads = MAP=20 settings - so what is a MAP, and if it's different because the = pressure is=20 different at different places in the inlet, how can the computer = calculate=20 the inlet charge and timing.
I'm confused!
