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.

Testing map (don't run this permanently):

Compare that to stock map:

Update: Here is my final map for stock application, this should be safe to run on stock downpipe/intake car (I made this map with catless uppipe).

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.
