    I don't believe the gateways calculate gallons burned. They simply report what the ECM is broadcasting. It would be news to me if they did.

    Sorry, good point. I should have said the fuel flow per engine reported at the plotter is the same as flow reported in the app, so the gateways are seeing the incorrect flow

    And to the point of the data, the engine doesn't really measure fuel flow in the traditional sense. It calculates it based on how long the injectors are on. They are usually pretty accurate, but in my case The fuel pump wasn't delivering enough fuel, so the injectors were staying on longer, reporting a larger fuel burn than it really was. Interesting that yours is reporting a lower fuel burn. I'd repeat the test just to make sure that wasn't some anomaly. I've had the mechanical flow sensors with gps input to calculate MPG and total burn. It was within 5% or so. Once you see it, you don't want to see it anymore ;-)

    I’ll get a good test tomorrow morning, I’m running back across the lake from Toronto and should be down about 70 gallons. I’ll report back. Thanks!

    So it was off again by the same percentage. I found in the settings on the app you can change the fuel burn calc. I set it to 1.65 and I think it’s dead on now. We burned about 70 gallons so I’ll fill up soon and find out how close it was

    Nice, I didn't know that was there. Dedicated fuel flow meters have a calc adjustment as well. Now I'll have to check mine for accuracy.

    To close the loop on this, finally had a chance to fill up with my adjustments and it is absolutely spot on now. Was two gallons off, but I ran the genny for 2 hours which should be about a gallon an hour. Turns out we run at 1.3-1.4mpg, which is still pretty dang good

    Can this run straight to Bluetooth without connecting to a backbone? Does it get its power through the backbone?

    Thanks.

    I’ve never tried to disconnect the backbone. However, I think it’s powered from the backbone, not the ECU.

    I just finished winterizing this past weekend. Otherwise I’d try to disconnect it and see what happens.

    they get their power from the n2k backbone but you could do a simple setup with 3 T’s, two end resistors, and the switch 12v power. If you’re not hooking up to an mfd no need to run a long backbone cable.

    The gateway has to get power. Normally, that's the backbone. you can power them directly, and use Bluetooth to your phone.

    The NMEA 2k cable needs power. When I supplied engine data through the backbone to my Garmin chartplotter, I used this - it was very simple. You'll note the starter kit comes with a power cable. The only other part I added - aside from the two Fox Gateway boxes which worked exactly as advertised - was an $8 switch with a light in it so I knew the system was powered.
