You mention -10 in 40 C temps..that is 104 F, damn warm. Exactly what the IICE does to fuel/air ratio at that -10 setting and at that air temp is a mystery to me...even though JJ once explained it to me I have gone blank...common malady! I am hoping it puts more fuel in than would otherwise be added at that temp.

As you point out there seems to be a disparity between -10 [hot] vs -30 [cold] and intuitively it should be reversed; lower temp reading in really hot weather [-30] to get more fuel to cool engine, even if cooling is not the primary objective.

Still do not have a clue how you would use the BP and IICE together. Or what the outcome would be.
Instead of thinking about it from a temperature vs. air density perspective, think about it from a temperature vs. fuel evaporation perspective instead.

The hidden harmony is found with joy, while the obvious brings indifference.
The farther you enter into the Truth the deeper your conviction for truth must be.
There is understanding of the world precisely to the degree that there is understanding of the Self.
