    Fuel Pressure and Oil Pressure pegged high

    I've got an AF-3500EM and am testing out the system prior to engine start. I purchased the system from someone who was going to use it with a rotary engine, but I'm going to use it with an O-320. I have (I believe) the correct sensor and wiring kit for the Lycoming.

    With the system powered on, the Oil Pressure reads 122.6 PSI and the Fuel Pressure reads 61.3 PSI. I'm sure something isn't set up correctly but I don't know what. Here are the details:

    Oil Pressure (122.6 PSI at rest)
    sensor 41,115 (0-150 PSI) - connected to white/yellow wire
    Other terminal on sensor grounded.
    A/D value=41 in the calibration menu
    Sensor gets a red X when I disconnect the wire.

    Fuel Pressure (61.3 PSI at rest)
    sensor 41,215 (0-30 PSI) - connected to brown wire
    Other terminal on sensor grounded.
    A/D value=42 in the calibration menu
    Sensor gets a red X when I disconnect the wire.

    I think I'm running software version 7.3.7-MV15 on both the 3500 EF and EM.

    Thanks for any help,
