With the warm weather here, I wanted to play more with AVCS. Previous best highway MPG was 26.9mpg with this tune plus Closed loop to Open Delay disabled.

New map:

Compare that to stock map:

This increased the gas mileage to 28.1mpg with AC running full blast! Please note this is actual MPG (not gauge) done by calculating miles driven divided by gallons filled up. I also account for speedometer inaccuracies (mine is off by -1.5%). I'm surprised it's this high with closed loop to open loop disabled, usually that will lead to worse gas mileage because you hit rich AFR's instantly instead of having a buffer of leaness when you add throttle.
