I have a customer with a 912iS and complete Skyview system. Everything is working great, except we seem to have fuel pressure variations from 37-44 PSI.
The sensor has once held a value with no pressure in the system, cycling the pump made the sensor respond and fall back to 0. So while it could be a faulty sensor, I don't think so. Yes it is the correct one and the correct setup.
So with the sensor/MAP/ambient pressure derived fuel pressure, I would expect the indication to be fairly consistent, but it appears that when you have reduced MAP during descent and landing the indicated pressure drops to around 36-37PSI. According to Rotax manuals this is bad.
I would like to hear from other users of what actually goes on, or does my customer have a pressure regulator problem?
Keen to be educated on my first 912iS experience.
