Turbo - No Fuel Flow

Voxen

In SPAD.Next data inspection, BKSQ_FuelFlow_1 is not updated at all (value is always 0 and never changes), while priming or when engine is started and pushed up to 20mp.

GALLONS PER HOUR, I don't find this variable at all.

Also I noted that once engine is running, the FF needle only start to move around 18mp, not below.

This might be helpful for troubleshooting: in the stream of pilotdeviation, there was also no fuel flow in the non-turbo version: time index 00:34:40 https://www.twitch.tv/videos/2837089058

FWIW I see fuel flow on the TN. But the needle is indeed quite sticky.

I did another test and found something interesting.
This time, the fuel flow indication didn't increase again, even after tapping the gauge. The EDM showed that fuel flow was increasing normally, so the engine itself was receiving fuel correctly.
Since I had previously completed a flight where the gauge worked as expected, I tried to figure out what was causing the needle to stick. It seems to start sticking at around 16°C. By 20°C, the needle no longer moves upward at all, even if I tap on the gauge.

What is strange is that I’m 100% sure to have seen the needle moving as expected at least once, most likely on the very first flight after purchase where I carefully followed the entire checklist.

Hi, everyone. I looked into this more today, and found the obvious: The fuel flow gauge is highly non-linear at the very bottom of its scale. Since these real instruments are full of real mechanical eccentricities, I've just added a little piece of "cheater" code to help boost the fuel flow indication just enough to read on the scale. Hopefully that should help eliminate any confusion.

Oh one one eight nine nine nine, eight eight one nine nine, nine one one nine, seven two five . . . . . . three.

I just noticed something today. First I started flying the turbo version of the commander and got that fuel flow needle not moving when priming (always). Then I switched to the normal version for a few flights, and there the needle is moving as expected. And today I have done another flight with the TC version and guess what: the needle was moving!
I can't find the logic there, but that is maybe something useful for you.
