Phil,
Are you ignoring me

Rich,
Unless your inlet manifold is the same as Phils, any tests at idle
are irrelivant.
Nick,
The monitor reads RAW data from the map sensor and performs
limited digital filtering.
The ECU internal value is highly averaged.
In any case the ECU only has 8 bit resolution and the map sensor isnt
that accurate anyway otherwise it would cost much more to buy.
