I need a little help here with this Mode 8 stuff. Ed, I did
some tweeking at cruise today to check the timing, and then I
remembered why I quit trying last time!
Testing was done at 4000 MSL, 80F, 4800 RPM, about 23 inches
MAP.
I get absolutely no change of anything in the "increase"
direction. In the "decrease" direction, just one click gives me
a drastic 2 GPH drop in fuel flow, and the EGT shoots up with a
noticeable loss of power. More clicks in that direction change
nothing. No matter how many clicks I go toward the "decrease",
it only takes one click back to the right to restore the original
condition and more clicks to the right change nothing.
Am I going nuts here, or what???? I did it several times at
different RPMs, etc, and always got the same sort of results. It
is like a two-position toggle marked "good/bad"! I have checked
the static timing previously, and it is right where the instructions
say to put it.
Ideas????
