Adam Posted August 16, 2016 Report Share Posted August 16, 2016 My new CTLSi has a 912iS Sport engine with an auxiliary fuel pump that you turn on for takeoff and landing. When the aux pump switch is off, the gauge for fuel pressure reads in the green and does not deviate in any phase of flight. Green is a range between 42.1 to 45 PSI according to my Skyview setup menu. When I turn the aux pump on, the pressure increases (seems logical) however it goes into the yellow arc and an audible "Fuel Pressure" warning is enunciated by Skyview. The Yellow range is 45.0 to 46.4 PSI according to my setup menu. On a takeoff roll as you increase throttle, hearing "Fuel Pressure" in your ear can be unnerving at first (and then later, annoying). The pressure never goes into the red and after takeoff when I turn the aux pump off, back to the green it goes. Questions for those of you with 912iS engines: 1.) Do you experience this phenomenon? 2.) If you go to "Setup" on the Skyview, and enter the "EMS" page, then "Fuel Pressure", I'm wondering what your "Range 5" yellow settings are? (mine are 45 to 46.4). I'm wondering if my yellow arc range is set up correctly? Quote Link to comment Share on other sites More sharing options...
