I previously complained about SV not displaying tenths of a liter when using the red cube or CAN bus fuel flows in litres. I think I might have fixed it, at least for the CAN bus widget. On a hunch, I went into the sensor file and changed the display setting from 1 to 2 decimals an the resolution from 0.1 to 0.01.

For some reason the CAN fuel flow widget now displays tenths of a liter. I will do some engine testing to see if this is actually correct and also check the fuel computer accuracy. I wonder if the original issue is a conversion error.

A check of the CANBUS specification suggests the data from the ECU should be resolving down to 0.05 litres if Rotax is exactly following the protocol.
