CUB CRAFTERS
CC18-180
Procedure
1
Establish cruise at approx. 65
to 75% power.
2
Pre-lean the mixture to 50°F
estimated rich of peak EGT on
any cylinder ___
3
Wait one minute
4
Tap the LF button
5
Lean the mixture - approx.
10°/second without pausing -
while observing the display.
When there is a 15°F rise in
EGT, LeanFind mode
becomes active.
6
Stop leaning when a column
begins flashing. You will see
LEANEST for two seconds,
followed by:
7
If you hold LF, peak EGT will
be displayed while the LF
button is held down.
8
Slowly enrich the mixture.
The temperature will
increase, returning to peak.
Stop enriching at the
desired EGT.

Comments
*For your first flight with the
EDM, use the method shown
Let engine stabilize.
Start LeanFine. (Optionally to
change to "lean of peak"
method, hold both STEP and
LF simultaneously.)
Flashing cylinder DOT
indicated hottest cylinder
and that LeanFind mode
Flashing cylinder dot &
column indicates leanest
cylinder. (SET means Set the
mixture.) Due to thermal
inertia this will usually be
about -15°F lean of peak.
Captured peak EGT value
is displayed.
