Fuel K factor setting changing by itself.

[JohnWF]

Dynon D-180...fuel K factor changes . I re-set it and all is well and this is not a critical item, but I wonder why it happens. This is the second instance of it changing by itself.

It could indicate something is up with the D180's memory. How often does it change and by how much?

The K factor has changed from 73,000 to about 65,000 as I roughly recall...took about 6-8 months for the change...I just noticed the GPH reading was increasing and checked K factor and found it had changed. This is not so important that I want to do something about it; just curious though.
