A detailed list of faults reported by the Rotax 912iS engine computer is shown under EMS >
FAULTS. Normally, it should say NONE. Consult your Rotax service organization for details of
what to do if a fault is shown.

LEAN
The engine monitor provides multiple methods to assist you in setting the mixture of your
engine for various functions. The first, and most basic, is to just watch the EGT display as the
engine is richened or leaned. You can watch for the EGTs to peak and then richen or lean as
desired from that point. The engine monitor also includes a leaning function to automate this
process.
To activate leaning mode, press LEAN. With this mode activated, LEAN highlights, and the label
“LEAN” is displayed underneath the EGT bars to clearly d
ifferentiate it from the normal
operating mode. This is depicted in Figure 72.

Entering Lean Mode
As each cylinder peaks, the cylinder numbers on the left side of the EGT bars are replaced by a
number indicating the cylinder peak sequence, followed by the difference from its peak
temperature (on combined EGT/CHT graphs pages, this information replaces the EGT
temperature itself due to space constraints). Given this information, you may set your mixture
more accurately to achieve a given EGT delta value on either the rich or lean side of peak EGT.
This is depicted in Figure 73.
