21.2.1.2 Lycoming/Continental Fuel Pressure
Fuel pressure sensors for Lycoming and Continental engines are not included in the Garmin sensor kits,
due to differences between pressure ranges for carbureted and fuel-injected engines. For monitoring
Lycoming/Continental engine fuel pressure, select a sensor from Table 21-1
as appropriate:
• Fuel-injected engines typically use the Garmin GPT 75G sensor (0-75 psiG, Garmin part number
011-5783-20).
• Carbureted engines typically use the Garmin GPT 15G sensor (0-15 psiG, Garmin part number
011-05783-10)
NOTE
Lycoming EIS display ranges are typically set to correspond with the pressure at the inlet to
the fuel injector. Continental EIS display ranges are typically set to correspond to
unmetered fuel pressure values.
21.2.1.3 Lycoming iE2
The G3X system is capable of monitoring the following engine parameters from the Lycoming iE2
FADEC digital interface, when connected to a GEA™ 24 engine interface module:
• RPM
• Manifold pressure
• Oil pressure
• Oil temperature
• Exhaust gas temperature
• Cylinder head temperature
• Turbine inlet temperature
• Fuel pressure
• ECU bus voltage
