Ambient temps have a huge effect on AFR's.

What EFI system do you have?

Do you have an inlet temp sensor scale that you can adjust for air temp changes?

According to the ideal gas law, air temp readings may not be completely linear.

My scale is a little slopey to accommodate different ambient air temps to maintain same AFR's.
