Bigstuff3 GEN3 PRO SEFI DAE Option - User Manual
Fuel Pressure
The fuel rail pressure can be logged to ensure that the rail pressure differential remains constant. This
is extremely important for turbo applications where rail pressure needs to increase with boost pressure.
The logged fuel pressure data provides the user important insight into whether the fuel pump(s) is
capable of maintaining a constant fuel rail pressure differential during critical boost events.
BigStuff3 recommends using pressure sensor part number JMI-003-014 (1/8” pipe thread, 0 – 150-psi
pressure transducer) for this application. The Fuel Pressure harness connector was made to interface
with part number JMI-003-014.
The same pressure sensor can be used for measuring turbo back pressure and oil pressure!
Oil Pressure
Engine oil pressure can be logged to ensure that the pressure remains constant across engine RPM
range.
BigStuff3 recommends using pressure sensor part number JMI-003-014 (1/8” pipe thread, 0 – 150-psi
pressure transducer) for this application. The Oil Pressure harness connector was made to interface
with part number JMI-003-014.
The same pressure sensor can be used for measuring turbo back pressure and fuel pressure!
