Address 37 ,
MAP 12.1, RPM 3010, Val +26, O2- 14.5 Tuned perfect. Move the throttle up
and down the map table and engine starts to run poor in the address range. Adjust throttle back to
Address 37 and things have changed.
Address 37,
MAP 12.5, RPM 2270, VAL +26, O2- 12.5 Tuned rich.
I have tuned this range a dozen or more times. It also
happens to be right in my taxi range.
Ground run settings.
Prop in fixed mode at high rpm
setting.
Supercharger 1" bypass open so no air is
being compressed in manifold.
Prop and supercharger settings do not seem to make any
difference with this problem.
I played around with mode 7A changing the rpm vs
manifold reference points but did not seem to make a
difference.
I can idle at 10" MAP and 1200
rpm.
Any ideas?
