SECTION 9.4 CUB CRAFTERS
SUPPLEMENTS-EDM-800 CC18-180
The EDM will indicate success in finding a peak by
displaying the words LEANEST for two seconds, followed
by flashing the column and displaying the value of the
EGT of the cylinder that peaked first. The word SET will
also be displayed. (With the Fuel Flow Option the current
fuel flow rate will be displayed on the right side of the
digital display instead of the word SET.) The flashing
cylinder will be locked—or set—into the digital display
during the remainder of the LeanFind procedure to allow
you to set the final mixture. The peak EGT value is
remembered by the EDM and will be displayed as long as
you hold the LF button.
You may now enrichen the mixture to operate at peak or
continue enriching until the EGT reaches a temperature
consistent with the procedures defined in your aircraft's
engine manual. If you lean too much, the EGT will drop
and the engine will be operating lean of peak.
9.4.7.10 True and Delta Rich of Peak
TRUE EGT: After peak EGT is found using the "rich of
peak" method, the left display will show the true EGT of
the first cylinder to peak. As you enrich the mixture, this
value will climb to peak. You can stop leaning when you
have reached the desired temperature, either peak or
continue to some value rich of peak.
