efi&mpg readout possible?

[Gerard]

I also thought about this a while back. That potentiometer, doesn't it
only read how high the plate has travelled in the metering head? Would
this perhaps not be related to air consumed, which could be similar to
the manifold pressure? When it comes time to do this on my 200t I will
simply be wiring up the MAP sensor to replace the potentiometer signal
and then just see what happens. Then maybe trying using the throttle pot
as well, otherwise to hell with it. I only used to get about 300 miles
out of a tank (18 gallon?). :P
