Fuel Pump Fixed Duty Cycle: The duty cycle used when in
fixed duty cycle mode.
Fuel Pump Desired Injector Pressure Drop vs. Mass: This
is the desired fuel pressure for mass flow.
Fuel Pump Desired Injector Pressure Drop High Load vs.
Mass: This is the desired fuel pressure for mass flow at high
load.
Fuel Pump Injector Pressure Drop Adder vs. Ambient Temp:
This adds to the injector pressure drop in relation to ambient air
temperature.
Fuel Pump Voltage vs. Flow vs. Pressure: The commanded
pump voltage in relation to flow and desired pressure.
Fuel Pump Adaptive Voltage: Master enable/disable for
Fuel Pump adaptive voltage function.
Fuel Pump Gain - Derivative: The derivative gain on the
fuel pump control terms.
Fuel Pump Gain - Integral: The Integral gain on the fuel
pump control terms.
Fuel Pump Gain - Proportional: The Proportional gain on
the fuel pump control terms.
Fuel Pump Gain Voltage Deadband: Fuel pump voltage will
not be corrected if desired change is less than this.
Fuel Pump Low Limit Mult: Sets a lower limit for the
fuel pump voltage, multiply by the base voltage lookup.
Fuel Pump High Limit Mult: Sets an upper limit for the
fuel pump voltage, multiply by the base voltage lookup.
Fuel Pump Update Time: The minimum time between
updates.
Fuel Pump Time Constant: The rate at which the pump
voltage will adapt when required, lower numbers are faster.
Fuel Pump Pump Off Duty Cycle: Duty Cycle when pump is
off.
Fuel Pump Minimum On Time: The minimum amount of time
the fuel pump can be activated.
Fuel Pressure Test
Fuel Pressure Test Fail Time: The fuel pressure test
failed for this length of time. P0190, P0191, P0192 or P0193 will
be set.
Fuel Pressure Test Fail Delta: If the fuel pressure
changes more than this, the fail timer will begin.
Fuel Pressure Test Error Buffer: The allowed error on
the actual fuel pressure before the low pressure test will
begin.
Fuel Pressure Test Low: If the actual pressure minus the
Error Buffer is lower than this value then the low pressure test
will begin.
Fuel Pressure Test Drop: If the pressure drop is lower
than this value then the low pressure test will begin.
Ambient
Ambient IAT Delta - Ambient Update: The difference
between ambient and IAT to trigger an update.
Ambient IAT Delta: The minimum offset of ambient from
IAT.
Ambient Update - ECT Min: Below this ECT, ambient temp
update will be disabled.
Ambient Update - VSS Min: Below this speed, ambient temp
update will be disabled.
Ambient High Pressure Switch Thresh: Above this
temperature the fuel pump will switch to higher pressure and use
the ambient temp adder table.
Ambient Inferred Time Constant: Time constant for
calculating ambient temperature changes.
Ambient Adder(AC On): Ambient temperature adder for when
AC is on.
Ambient IAT/ECT Factor During Soak: This factor is used
to weight between ECT and IAT during soak periods. Numbers closer
to 1.0 weight towards ECT and numbers closer to 0 weight to
IAT.
