LeanFind Mode—Leaning Rich of Peak
•
JPI’s EDM-760 provides two methods of leaning: lean
rich of peak (
LEAN R) or lean of peak (LEAN L). The
standard method is to lean about 20° rich of peak. With the
advent of GAMI injectors it is now possible to set the mixture
lean of peak—saving fuel and running the engine cooler.
Teledyne Continental recommends lean of peak for the Malibu.
This manual primarily describes the rich of peak method, and
provides the procedure for the lean of peak method. The
factory default method is set to rich of peak, but you can
change this to lean of peak.
Simply pre-lean, tap the LF button and begin leaning. Upon
reaching cruise configuration, you will use the LeanFind mode to
identify the first cylinder to reach peak EGT.
A more detailed explanation of the LeanFind procedure follows this step-
by-step procedure.
