Just an update.  We seem to be seeing pretty wonky MP numbers on the EM2

At the lowest RPM where we can get the engine to run relatively smoothly
(1500rpm or so) we see a MP of 13.2 or so.

Bump up the RPM to 1800, and the MP drops to the neighborhood of 12.2.

RPM to 2100, and MP is back at 13.2 or so.

Keep bumping up rpm and... MP stays at 13.2.

Finally, at 4000 rpm, the MP jumps up to above 15.0 & from there it
increases relatively constantly.

Max static RPM turns out to be 6600rpm, with a MP of 20.7.

It will interesting to compare these values with whatever gets recorded by
Paul's magic pressure sensor to better understand why these readings are the
way they are.

If I can get the silly thing to work right.
I might have to get a back up system.
