NOTE
All the numbers given are examples and should not be
construed to apply to any particular aircraft.
If you are unfamiliar with the aircraft and do not have an
estimate of the value of peak EGT, establish the aircraft
in a cruise configuration while in cruise at 65% power.
Choose any cylinder and lean that cylinder to peak EGT
in the Manual mode or until the engine runs rough,
whichever occurs first. Note the peak, subtract 50° and
record the resulting number for future reference.
Lycoming has established specific restrictions on leaning
that must be followed, such as percentage of power, and
climb leaning. Lycoming recommends operation at peak
EGT for power settings of 75% or lower. This guide is
not meant to supersede any specific recommendations of
the engine manufacturer or airframe manufacturer. It is
your responsibility to know your aircraft's limitations. Pre-
lean the mixture to about 50° below peak. After pre-lean,
wait for one minute for the temperatures to stabilize.
Next, begin the leaning process by tapping the LF button.
This tells the EDM to begin looking for a 15° rise in EGT
for any cylinder. Begin leaning the mixture without
pausing. When a 15° rise occurs, eliminating false
peaks, the LeanFind mode becomes activated shown
when the cylinder dot above the column of the hottest
cylinder begins flashing. The LeanFind mode is not
active until a cylinder dot is blinking.
