spark and MAP

[Bruce Bowling]

~

~ I was inspired to design my own ignition controller by Tim Drury's DDIS project article (thanks).
~ I'm thinking of later adding also a separate  EFI system, but that will require some more 
~ study and reading of this list...
~ 
~ I have one open question: Is there a real benefit in adding a MAP input to an 
~ ignition system, or do the timing just by rpm curve?
~ 
The MAP sensor is the equivalent to the vacuum-advance on a distributor, and
the rpm curve is equivalent to the distributor flying weights.  If your car
runs fine without vacuum advance, then you do not need the MAP.
