Full g3x system, gea24, all Garmin sensors. Coming up on the 2nd annual and my 2nd manifold pressure gauge is on its way out. If the manifold pressure is less than 10-12", the g3x gauge goes to zero. If it stays there long enough I'll get a red x which goes away when the throttle gets pushed back up. It normally seems to be accurate when the MAP is 20" or higher, but today I was doing stalls and noticed the g3x was reading 15" while both my SDS gauges were reading 25". This is the 2nd time this has happened, and the first time I replaced the sensor and checked all the lines and connections for an air right seal. I didn't find any leaks or damage and the problem seemed to go away for a few months after replacing the sensor.
I run a 3an line off cylinder 4 to the Vans provided firewall sensor tree. The restrictor elbow is mounted on the bottom of the tree. The sensor is on the top. Is having the restrictor that close to the sensor killing the sensors? I would really like to solve this one at annual later this month.
