This automatically opens the definitions for that specific parameter. ‒ When navigating the software, click "Help ?", drag it to any parameter and click again. ‒ On the top Toolbar, click "Help" & "Contents". EFI Software Help Information/Instructions:.The dome pressure sensor should be a 554-102 pressure transducer, or a 554-108 5 bar MAP sensor (depending on yourīoost psi - LINK).
PSI TO KPA CHART MANUAL
(Holley EFI Wiring Manual - Section 2.1 "Pin-Outs", Pages 6, 7 & 8)
However, if using the PWM+ Outputs, they should be wired on the J2B connector. The Dominator ECU can use either type of Output (PWM− or PWM+) for the boost solenoids. The HP ECU should use PWM− type of Output for the boost solenoids ( LINK). The solenoid +/− "Output Type" is selected in the Inputs/Outputs screen of the Boost ICF, then Pin-Mapped. The "Boost −" solenoid is the "Vent" solenoid, and the "Boost +" solenoid is the "Fill" solenoid.
The Holley EFI electronic boost controller uses one input & two outputs for the dual boost solenoid control type. (Enter kPa at left, and select psig or psia at right.) Here's an excellent pressure conversion calculator: (Read "Gauge Pressure" toward end of page one.) Every 6.9 kPa over 101, is 1 PSI G of boost:ġ bar MAP = 100 kPa / 00.00 PSI G - 14.70 PSI A (sea level - naturally aspirated)Ģ bar MAP = 200 kPa / 14.31 PSI G - 29.01 PSI A (sea level - forced induction)ģ bar MAP = 300 kPa / 28.81 PSI G - 43.51 PSI A (sea level - forced induction)Ĥ bar MAP = 400 kPa / 43.32 PSI G - 58.02 PSI A (sea level - forced induction)ĥ bar MAP = 500 kPa / 57.82 PSI G - 72.52 PSI A (sea level - forced induction)Ħ bar MAP = 600 kPa / 72.33 PSI G - 87.02 PSI A (sea level - forced induction)ħ bar MAP = 700 kPa / 86.83 PSI G - 101.5 PSI A (sea level - forced induction)įYI: The Holley EFI software MAP kPa load scale (Y axis) will display:ġ bar-105 kPa, 2 bar-210 kPa, 3 bar-315 kPa, 3.5 bar-350 kPa, 4 bar-420 kPa, 5 bar-520 kPaĭon't confuse PSI G (boost gauge) & PSI A (absolute with atmosphere):
