21.2 Engine Sensor Applications
21.2.1 Lycoming/Continental Engine Applications
Table 21-2 and Table 21-3 list Garmin sensor kits available for G3X installations with 4-cylinder and
6-cylinder Lycoming and Continental piston engines. Refer to Sensor Interface drawings in Section 27
for
sensor wiring guidance.
For 8-cylinder Lycoming engine applications, refer to Section 21.2.5
.
For retrofit applications, where a G3X system is installed in a completed aircraft with a Lycoming/
Continental engine, refer to Section 21.2.6
.
21.2.1.1 Lycoming/Continental RPM
Engine speed for Lycoming and Continental engines may be sensed by an RPM sensor mounted on the
mechanical tach drive, a sensor mounted on the magneto, or through the digital tach signal output from an
electronic ignition system. Refer to Section 21.3.5
.
