The unit is capable to display the actual fuel consumption of the engine by two different ways:

Through J1939 fuel consumption information

By counting fuel consumption pulses.
If the engine is sending the fuel rate through J1939 messaging, then the unit will directly display the fuel
consumption information coming from the ECU.
If a flowmeter is installed at the fuel suction hose of the engine, then the unit is also capable of counting
these pulses, calculating and displaying the fuel consumption.
