Problem with D180 Fuel Display...
 
I have dual screen Dynon D180 and D100 in my RV-12. I just recently recalibrated my fuel quantity gage per Dynon instructions. Now I notice that I no longer get a yellow box around the digital number of gallons remaining at 7, nor do I get a red box (steady or blinking) around the digital number of gallons remaining at 3.5. This used to work fine and I would also get warning on bottom of screen which needed acknowledgement.

I have contacted Dynon and they tell me that the unit they have on bench does exact same thing. They were a little surprised and don't have a solution.

Anybody else having this problem?

Maybe change that 7 and 3.5 to something else,now that you have re calibrated sensor, then you can move both back to 7 and 3.5 . Thinking that the re calibration may have voided those original limits for red and yellow. Just a shot in the dark

Probably unrelated, but do you have 2 fuel pressure readings?

I'm not following your question. The screen shot in my first post is the EMS screen and I guess it shows fuel pressure in two locations. Fuel quantity is also shown in two locations on the same screen.

I thought if during your recalibrating of your fuel level, perhaps you erred in some way, ie 2 indications of fuel pressure, one beneath the oil temp indicator, and one in the lower right of screen.

Having worked with Dynon for a while as a beta-tester, I can tell you that if (A) their on-the-bench unit did the same thing, and (B) it was a thing that it shouldn't be doing, AND (C) they couldn't tell you what to do next, then they are certainly digging into the software code behind it and will have an answer shortly.

I hope so... I'm afraid there is limited support for the legacy equipment.

Just strange that all the other warnings are working - oil press, temps, but not low fuel quantity.

I contacted Dynon about my D-180 fuel gage problem (see post #1 above) and they tell me none of the software engineers who designed the D-180 are working at Dynon on anymore. Dynon also tells me they have powered up several more D-180's in-house and none of them have the yellow/red boxes around the digital number for gallons remaining in tank.

So, maybe I don't remember this correctly... Can anyone verify that they see yellow square and red square & red square blinking around gallons remaining digital number for a D-180? Also, do you get visual warning on bottom of screen for minimal gallons remaining (in my case - 4 gallons)? And while we're at it... do you get audible low fuel warning in your headset?

Maybe I'm getting too old for flying...

D180
 
I ran my right tank low in my 8. My D180 goes green, yellow, red flashing, with audible and visual screen flashes.

Thanks guys. Today Dynon said they got their in-house D-180 fuel gage working correctly by re-loading Van's locked settings file. I'm going to put this task off until end of flying season. Good to know there's a fix...
