Re: Manifold pressure off MAP sensor?
Normal atmospheric pressure at sea level is about fifteen pounds per
square inch, which of course not a vacuum, that would be then read in
inches of mercury. So, sane people would measure that fifteen pounds as
just ZERO, and use the typical manifold gauge:

Well, that's not the way that makes sense to me.
Absolute pressure makes more sense. And using ONE unit instead of two
makes even more sense. Anyone who has flown or worked on an airplane
with a constant speed prop is guaranteed to agree.

So get one of those gauges, like in Bill's picture, take off the cover
glass, and paint a new dial on it.
