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.
