12. Fuel Pressure sensor

QUICK INFO

A fuel pressure sensor can be connected to the PBC-PRO to display the actual differential fuel pressure and protect the engine from fuel starvation problems.

Currently only the following sensor is compatible and should be used.

SAFETY WARNING!

Please study the sensor installation instructions as provide by AEM before attempting installation.

STEP 1

Connect Analog Input 1 - YELLOW or Analog Input 2 - GREEN wire to the signal output of the sensor.

Connect the red +5V power supply wire from the PBC-PRO pin 11(this wire is also used to supply power to the PBC-PRO map sensor) to the AEM sensor +5V power supply pin.

Connect the blue GND wire from the PBC-PRO pin 7(this wire is also used to supply ground to the PBC-PRO map sensor) to the AEM sensor SGND pin.

STEP 2

Set the selected analog input as "FUEL PRES 1" in menu5.6

STEP 3

Set the desired minimum differential fuel pressure limit in menu6.9.

When the actual pressure goes bellow the set limit a warning message will be displayed and the boost will be limited.

Hint:

The differential fuel pressure is the difference between the actual fuel pressure and the manifold pressure.

With a boost referenced fuel pressure regulator it should remain fairly constant under all conditions.
