I reset the EC2 to the "RV-Otter" settings (cold start on),
and it is very close now. Got rid of most of the staging stutter too!
Now a question about oil pressure for the group. Since I removed
the balls and springs from the rotor jets and have stock jets, here are my oil
pressure readings. Somebody let me know if this looks like enough flow.
and at idle RPM with Oil Temp at 170,

Latest software for
the EC2 addresses this problem. If you haven't upgraded since
around Mar 2005, this is highly recommended.
In the mean time, I
suggest 16 - 17" Hg for staging point. Yes, changing staging
point means you have to re-do the map table in this area. In the
mean time, If you are having this surge and have an EM2, step to the
map entry just above the staging point and richen it and the next
two about 30 - 40.
This problem is
usually caused by the engine going lean right after the staging
point. You can do it without an EM2 but it requires a bit of
finesse. Turning up the mixture control will also eliminate the
surge but the engine will probably be running rich under the staging point.

If/when you find a
solution to the annoying surge during high idle/taxi
let us all know what
it is.
I too am experiencing
this annoyance.
I think we need to set
the staging point higher but have not tried this yet.
Now that the engine is
running correctly again, I have to start all over again programming my
EC2! That nasty crossover point at 15" MAP is giving me an
annoying surge at a high idle (taxi) speed. Hope a close reading of my
manual will let me sort that out.
