High Fuel Pressure.

[rogersmart]

I have a Lycoming 0-360 with a Tempest LW-15472 fuel pump rated to put out 4-6 PSI.  In cruise the Skyview shows 10-11 psi at cruise boost pump off.  The boost pump shows 14 psi.  I am using the stock Dynon sender for a carbureted engine, connected to Pin 8.  When I installed it, pin 8 was already configured as a pressure sensor.  It has full range, 0 when engine and pump off.  I have grounded the sensor manifold, which did not change anything.  The oil pressure sensor is in the same manifold (separate port of course) and it reads right on, matching an installed analog gauge.   If I prob pin 8,  what should the voltage be engine off and what should the voltage be at 4 psi and at 6 psi? Any ideas what would make this read high?

Are you sure that you changed pin 8 to use a carb fuel pressure sensor in the pin mapping? Out of the box, SkyView comes configured for a fuel injected fuel cylinder as a default. You can manually change those settings, but we also have files that you can load that will get you a head start on the pin mappings and page layouts.

Thanks for the reply. Found the problem. Changed the type of sensor config from 0-80 to 0-30 and it now reads 0 off to 5.7 with boost pump on.
