I think I'm all calibrated now. I got the Oil
Pressure to stop being a
negative number.not quite sure how - but playing
around with parameter
6 (the other Scale Factor) in the range of 32767
(actually about 512
above it) seemed to set the sign bit and once set it
has remained.
 
I also discovered that the butterfly set screw on
the intake was down
a little too far - i.e. the throttle was open about
an 1/8" at idle. I
reset that to about 1/16" and started it up again.
Oh my, she
prrrrrrrs so nice now.  RPM now - still without prop
- is 1750-1800,
Oil Pres 65-70, Fuel Pres 50.
 
I ran it for about 5 minutes only cracking the
throttle a couple of
times just to see what would happen (can't help
myself) - and with the
tiniest of movement of the throttle it wants to jump
to 2500-3000 RPM!
So next - other than chasing little leaks of fuel,
coolant, and oil -
is mounting the prop and looking at the MAP to see
how well the
MicroTech stock settings fit. I've got an old Laptop
I've got to
rebuild so I can install the MicroTech software.
That will make
reviewing the Maps and Data Logs much easier than
trying to review
them on an LCD 2 line display (that's the handset
that comes with the
MicroTech).
