New F250TXR Fuel Flo

[Fishinfun]

Just installed a new F250 TXR on my 'o4 Sea Pro. Also installed lowrance red nmea network. Lowrance is saying that I can get fuel usage directly from the command link. My HDS-7 shows only a current flow as per the RPM's of the motor. How can I get the Actual Gallons used since last fill up?

What should the Yami send

What should the Yamaha motor be sending as part of the command link regards the fuel?

Don't know if the Lowrance has the capability. It would need to connect to fuel level sender in gas tank, program the amount of gallons of gas tank holds and calculate fuel used verses fuel remaining.
Yamaha Command Link speed/fuel or fuel management gauges has that capability.
