Thread: Fuel Press Values

  1. #1

    Default Fuel Press Values

    Hey guys, I've just put a stand-alone Digital Dash in my car. Got everything working except for the fuel pressure. Does anyone know what the volts/values need to be for the 0-100 psi sensor. Cheers.

    The Holley EFI 554-102 sensor has a linear voltage output range of .5 - 4.5 volts (0-100 psi).
    Volts - PSI
    0.50 = 0
    0.77 = 7
    1.03 = 13
    1.30 = 20
    1.57 = 27
    1.83 = 33
    2.10 = 40
    2.37 = 47
    2.63 = 53
    2.90 = 60
    3.17 = 67
    3.43 = 73
    3.70 = 80
    3.97 = 87
    4.23 = 93
    4.50 = 100
    May God's grace bless you in the Lord Jesus Christ.

    Is that table used for every 100 psi sensor?

    I can't say every manufacturer, but it's correct for most linear 100 psi transducers.

    Sorry, guess I didn’t state they were Holley.

    Yes, post #2 is for Holley's 100 psi pressure transducer (but it's already in the predefined drop down menu - Sensors ICF).
