Subject: Re: [FlyRotary] EM-2 MAP readings

I seem to have just the opposite problem.
With WOT I have no problem seeing 30-31"MAP whatever
is the pressure of the day.
My problem is at idle I never seem to get less than 
15" MAP. This would mean that I will always be running 
in staged mode with both injector set operating 
because Tracy set the staging point at 15". I know 
that this is adjustable but I'm wondering why I can't 
get <15"MAP.
Has anyone recorded a table of RPM vs. MAP for the 
range of 1000RPM-6000RPM?
I'm especially interested in the low end and would 
appreciate any input from our more experienced 
rotorheads.
