The G1 is the first low cost complete color graphic engine monitor system available in aviation today.

The G1 GEM offers the basic monitoring features for EGT/CHT and CT (Carburetor Temperature) as the other G-series GEMs but not the advanced leaning features (that require real-time fuel flow data).

All EGT/CHT/CT data is continuously displayed in color-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.

The 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.

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.

All G1 Kits ship with carburetor probe and SD card.
Standard model kits include a single engine 8’ harness, (4 or 6) EGT/CHT Spring probes and (1 or 2) TIT probes.
