Total Gallons used.

[BigFlapper]

I have the field "Total Gal. Used" set up in my Engine page but the value always shows 0.
Do I have to check this field before shutting down the Dynon?

Do you have a fuel flow "Red Cube" sensor?

What is the value set?

Are you seeing any information in Gal/min?

 

[dynonsupport]

Is this a EMS-D10, D120, D180, or SkyView?

You don't need to check it before shutdown. It is remembered for the next boot.

I have the red cube, set at recommended pulse/min.
The system is the Skyview 1000 and the GPM seems about normal for my engine. Just wanted to fine tune fuel flow.

 

[BigFlapper]

Just did some checking, it seems that I have set up both p14 and p19 for my fuel flow. If I understand this, it will give me a zero total fuel flow. Now I just need to remove the p19 fuel flow setting from the system.
Does that sound right?

Only if you had your fuel flow sensor physically connected to both inputs. The second input is nominally only used for return fuel flow systems, where the 2nd input is subtracted from the first. Now if you have it hooked up to p19 and NOT p14, then you might be railing against 0 fuel used (although I'd expect it might go negative)

I checked the connections and the red cube is connected to the yellow wire. No connections to p19. In the sensor debug I get C37 P19 unused and "raw" 0000
In fuel flow calibration it shows P19 at 68000 just like P14, I tried to set it to 00000 but it reset back to 10000.
In sensor input mapping pin C37 P19 is blank (unused).
Maybe it does reset to zero when I shut it off?? I'll check next flight.
