Note: Averaging constant cannot be used with CAN data, because this
information comes in digital format. So in order to prevent data loss, set
Averaging constant parameter to 1.
Most parameters have certain resolution. FEE9 parameter has 0.5L/bit gain, so value that is
sent to server has to be multiplied by 0.5.
Data parsing is preceded by selecting correct message from all available on CAN bus. FMS
standard interface description indicates that fuel consumption is parameter with ID FEE9:

The example indicates how fuel consumption message is selected and how configuration
impacts this selection (Figure 78 and Figure 79).

When certain message is filtered, FM5500 checks which data bytes should be sent to
server. Document indicates that 5-8 bytes are used in FMS standard.
