  • Smg4 gauge mpg?

    I got twin suzuki df140a. I have two smg4 gauges.
    I have nema them to my simrad go12. I can find them in device list. I cannot get the. To show mpg, it just shows ----
    They will show me gph. Does anyone know what I need to do to get mpg to read correct.

    I think the resident expert might want the year of the engines.

        I finally found a old post. Had to turn water speed off. Now if I can figure out why the main fuel bar up top is correct but if you cycle through the bottom the small fuel bar is way off.

          Yes good work finding previous posts on changing the speed source!

          As to the fuel tank bars - Im going to kinda pass on that, although it may be to do with fuel tank setup for twin engines?

          Here is the gauge installation manual. Have a look in there to see if you can find any clues, and if you do, dont forget to report back with results. Please!
