Data bytes are filtered by selecting the checkboxes in Output data mask. Note, that configurator has them listed starting with MSB.
After message is filtered it is attached to the data packet and sent to the server. Values are returned in HEX. 00 03 84 23(HEX) = 230435(DEC). Notice, that data resolution is 0.5L/bit gain – value has to be multiplied by 0.5, therefore vehicle used a total 115217,5 liters of fuel.
