The average fuel function uses the distance counters setup. Make sure to have the correct distance source set and that there is wheel speeds.
Fuel flow correction
Flow correction can be applied to calibrate the flow/consumption readings.
low load flow correction
Correction applied at low injector opening times to correct for injector non linearity.
Low load flow correction is only applied to the first 1ms of injector opening. This can be used to calibrate the flow/consumption reading on idle or light cruising loads.
Virtual fuel tank
An advanced feature for vehicles with no fuel tank meter inside to calculate the amount of fuel left in tank based on fuel consumption calculations.
Virtual tank volume
Specifies fuel tank volume.
Specifies how to calculate the fuel flow/consumption.
The digital function Virtual fuel tank reset level can be used to reset the tank level.
The digital function Avg fuel consumption reset can be used to reset the average fuel consumption.
