The Virtual Fuel Tank Function can be used to warn the driver when the volume of fuel remaining drops below a certain amount. This function uses calculated fuel consumption based off of injector PW, Differential Fuel Pressure and Injector characteristics, more specifically it uses the Accumulated Fuel Consumption value with additional code to reset the amount of fuel remaining and to remember the amount of fuel over ECU power cycles.

The amount of fuel remaining is shown by the Fuel Left runtime and the Fuel Low warning is displayed by the Fuel Left status.

 

The available settings are:


Fuel Added Mode

Used to define how fuel is added to the tank.

·Off - Sets Fuel Left to 0 and then does nothing.

·Volume added -  Adds the Reset Volume value each time the Add Fuel Input becomes active.

·Volume filled up to - Sets the Fuel left to the Reset Volume value each time the Fuel Added Input becomes active.

·Hold up/down - Adds or removes fuel at the rate specified by the Add/Remove Rate while the Add Fuel Input or Remove Fuel Input respectively are active. Making both inputs active at the same time will set the Fuel Left to the Reset Volume.

 


Add Fuel Input

Used to select the input which indicates when the virtual tank has been refilled (either to the top or by a certain amount depending on Fuel Added Mode).

 


Remove Fuel Input

Note: This setting is only visible when using Hold up/down mode.

Used to select the input which indicates when the virtual tank has been refilled (either to the top or by a certain amount depending on Fuel Added Mode).

 


Reset Volume

If using Volume Added Mode this setting defines the amount of fuel that is added when the Add Fuel Input becomes active.

If using Volume Filled up to Mode this setting defines the amount of fuel that the remaining value is set to when the Add Fuel Input becomes active.

If using Hold up/down Mode this setting defines the amount of fuel that the remaining value is set to when the both the Add Fuel Input and Remove Fuel Input are active at the same time.

 


Add/Remove Rate

Note: This setting is only visible when using Hold up/down mode.

Defines how fast fuel is added and removed when the Add and Remove Fuel Inputs are active.

 


Fuel left warning volume

The value of fuel left at which the Fuel Left status will display change to Error Low.
