I now have the airplane running pretty good
throughout the RPM range on controller A. Using Mode 9 I copied the program to
the B controller. I assumed that the engine would run the same (more or less) on
B after the copy, but no... Seems to be rich throughout the range - to the point
of mis-firing, surging, running rough, etc.... I think I can tweak everything to
settle it down, but is this normal? I assumed there may be differences in the
MAP sensor which would result in a small difference but really did not expect
such a drammatic difference. At most throttle settings I have to turn the
mixture full lean to smooth it out.
Does the Mode 9 copy just copy the MAP table or
does it also copy things like the staging point, the global injector setting,
etc...
If I can get this B controller dialed in I'll be
out of excuses - time to fly.
