Tracy, and
all,
I finally decided to try to
calibrate the fuel flow reading on my EM-2, and don't quite understand what I'm
seeing. I zeroed the fuel reading the last time I put fuel in the
plane, but yesterday, when I put 10 gallons in, the EM-2 said 20.7 had been
used. I spent some time fiddling with alarm limits, and
then noticed that the fuel read 22.4. Since the engine isn't
running, this represents poor fuel economy :-)
I also noticed that
the EM-2 always seems to read .3 gph when the engine is off, but even that
wouldn't account for the almost two gallons in the few minutes it took to set
the alarm limits. I tried turning the EC-2 on, and then off, to see
if that changed the reading, but it stayed at .3 gph. I don't think I can
change the sensor offset on this one :-)
Unless there's a simple
solution to this, I'll just ignore it, and defer the fuel flow calibration
until the new chips arrive.
Cheers,
Rusty (anyone want a
Sonerai-II)
