Everyone (Garmin Tech Rep),
I have a new G3X professionally wired and installed in a new build F-1 Rocket. The system has been flawless except for one repeat offender. The Manifold Pressure display functioned normally for ground test and for about 30 min of the first test flight. At this point the needle and digital display essentially froze and ceased to follow the throttle position. For example, when indicating 24" & 2400 rpm, reducing the throttle all the way to idle would not cause the MP display to change. It was not, however, frozen completely and would occasionally move from the frozen position a little.
After inspecting the MP wiring and hose condition, I concluded the problem was probably the Kavlico sender unit and replaced it with a new one. Subsequent test flights were normal at least for approx 2 hours and then it happened again.
I'm out of ideas... Any thoughts from the Garmin Experts or others who might have experienced this?
Thanks Gang,
Brad
