I think of it like a flowchart: If this happens, do that. The details of that map determine fuel mileage, so it’s hard to make a blanket statement.

When you said “…the EFI automatically compensates for the changing in temperature” does that mean that because the air:fuel ratio changed due to temperature, did the ECU give MORE fuel to get closer to the ideal ~14.7:1? And, can you calculate how much less mileage the teams would get with a 20 degree drop in temperature? Great post once again. Can’t wait for the 2nd part.
