The G1 GEM offers the basic monitoring features for
EGT/CHT/TIT and CT (Carburetor Temperature) as the other G-series GEMs but not
the advanced leaning features (that require real-time fuel flow data). Single Engine - 2.25 Bezel
All EGT/CHT/TIT/CT data is continuously displayed in
colour-coded bar-graph and numeric form, but neither mixture lean-of-peak (LOP)
nor rich-of-peak (ROP) indication is provided. Leaning boxes do appear
following peak-EGT events but the delta temperature number inside each
leaning-box only shows the magnitude of temperature drop.
G1The LOP or ROP
mixture status must be determined by the pilot by knowledge of which direction
the mixture control was moved following a peak-EGT event. Moving the mixture
control to increase fuel flow after finding peak EGT will result in a ROP
condition, and moving the mixture to reduce fuel flow after finding peak EGT
will result in a LOP condition. FAA & TC Primary STC EGT, CHT, & TIT
Users of the G1 GEM should disregard references to GEM fuel
flow indications in this manual. Similarly any feature that requires use of the
rotary control knobs or user configuration screens is not available on the G1
GEM and should be disregarded.

Warning – If you have a injected fuel system and planning or
running lean of peak the G3 is a better choice because you get:
First To Last Color Lean boxes - White LOP, Cyan ROP
By How Many Degrees - Number in box
What Fuel Flow Was At Peak On Every Cylinder - On every EGT
bar
EGT Variation
Spectrum - In-flight exhaust valve analysis
Advanced Data Logging - Every second of every function on SD
Card
