    Default Commanded fuel self adjusting disable?

    So I noticed that the commanded fuel will self adjust with a constant throttle input. Its not really a big deal but I was wondering if anyone knows how to disable this. That way the throttle table is explicitly what im commanding. In the pic I attached here i did my best to hold the throttle steady and you can see the commanded fuel increases and decreases inversely to RPMs.
    Thanks

    That's an Extrapolated value so there are several factors that go into determining it. To answer your question I do not believe that you can lock it in to a constant number and in reality you really wouldn't want to.

    Just to clarify I don't want to lock to a constant commanded fuel but rather stop it from compensating by adding more fuel when the rpms decrease. When I climb a hill the rpms will drag down and commanded fuel will go up, by some amount and vice versa. I made a little calc to interpolate the throttle table and give me mm3 and in my picture I should be at 20-23ish mm3. Its up in the 30s. I just wondered if it was done. This is for my own amusement.

    EDIT: Also that log i have pictured was over several miles, every peak and valley was caused by the hills i was in. I was averaging about 55mph ish.
