Pressure
Indicators
- Absolute pressure - the pressure in the fuel rail that the sensor shows
- Differential pressure = Absolute pressure - Intake manifold pressure
Differential pressure is used to calculate injection corrections.
Operating pressure
Specifies the operating pressure in the fuel rail. This is the pressure in the fuel rail when the vacuum hose is disconnected from the FPR.
The parameter must be set regardless of the presence of a fuel pressure sensor.
FPR without vacuum
Enables a constant pressure FPR mode
Fuel pressure corrections
Enables pressure and temperature correction algorithms
Fuel temperature correction
Specifies the percentage of fuel correction by fuel temperature
Fuel pressure correction
Specifies the percentage of fuel correction when the actual fuel pressure deviates from the operating pressure.
The pressure difference is set as a percentage
- 100 - the pressure is equal to the working pressure
- 50 - fuel pressure is 50% of the working pressure
- 150 - fuel pressure is 150% of the working pressure
No Idle fuel cut if the fuel pressure is higher
Disables the idle fuel cut-off in order to relieve excessive fuel pressure when the gas pedal is released. It is used for LPG/CNG injection
