O2 sensor rich/lean chart
Is there a chart to reference rpm vs map vs load to use to adjust O2 sensor switching mv for fuel mileage I see a lot of people using lower numbers in the center three boxes but when I watch my nb histogram my 04 Tahoe seams to be running little higher up the chart at a steady lean cruise?

I think I figured it out I made a histogram plotting maf lb/hr with maf kpa vs engine speed in the columns. Hopefully I can save a vcm scan and determine my airflow modes?

You have to translate the airflow mode to an airflow. Use the lookup table in the tune for this.

Thanks for the help. It sure is nice being able to tune to my liking instead of General Motors.
