LOP Temp shown as Celsius

[shenweas]

I have a Skyview Standard running the latest software.  Been running this particular unit for over 1100hrs now and just as of a month ago or so ago I was digging through the data logs working on a mixture distribution issue and comparing the data logs with the indications that I normally view on the display and noticed that even with my display set to Fahrenheit scale, when the engine is leaned to LOP and the display is in the Lean mode.  The indication shown is Celsius  :-?  All this time, it appears that I have been operating quite a bit farther LOP than I thought.  Is this intentional or a software problem?

-10C is just the difference. If it is in Celcius then (-10 x 9 / 5) = -18F. Not as lean as you thought.

Aaaaahhhhh.....reality check. Thanks for the math correction.

That display is showing that you are 10 degrees F LOP. We don't know of any issues with this function, and it does not change to C.

It's pretty easy to see that it's working as expected.

1) Go ROP
2) Engage the leaning mode
3) Lean slowly, and record the peak temperature manually
4) Lean until -50 or so is shown
5) Turn off lean mode
6) Verify that the current absolute temperature is the same difference lower than the peak you recorded
