Sorry it didn't work
out this time Steve, but it will, just hang in there.
Refresh my memory- which gear ratio do you have, and what rpm's are you
seeing in climb? What MAP are you running?
[Steve
Brooks] I have the 2.17 drive, and I'm seeing about 5300 RPM's in climb.
I don't have a MAP gauge, but rather a boost gauge. I could calculate
the MAP, but on take off, I'm setting the throttle to 5 lbs of boost, which
seems like plenty. Full throttle will produce about 8 lbs of boost, with
substantially more power.
1) I seem to be running
rich. I turned the fuel pressure down some (30 PSI on my gauge (don't
know if it's accurate)). That helped, but running both fuel pumps makes the
engine run very rich at full power. Turning off one pump increases power
and smoothness. At an idle, 1000-2000 RMS, if I shut off the main fuel
pump, the engine smoothes out, and gain a little rpm, before running out of
fuel.
This may be a dumb
question, but why not tune this via the EC-2?
[Steve Brooks] I tried that, and have it as lean as
it will go on mode 1. I haven't tune it above 4000 RPM's yet. I
can't hold the plane still with the brakes, and haven't been in the air long
enough to do it there. I may be able to resolve the rich running at
high RPM's. Mode 3 tuning doesn't seem to be
working.
2) For
whatever reason the "coil test" has stopped working. I used to be able
to go to the "B" controller, and do the coil test to check the leading or
trailing coils. That doesn't work, and if I turn it to off (I'm using
the ignition switch), it keeps on running. Used to kill the engine
before. I'm not sure what this is, and haven't really done any testing
yet.
First guess would be a fatigued
connection somewhere.
[Steve
Brooks] Could be, I need to check it out with the
voltmeter.

I've heard that praying can keep you
out of REALLY hot weather :-)

one Cozy driver at a time) - Lucky
