13.1 afr
To use the charts, I set my PEvsCool to 16 in all operating temps, this takes out the variable there.
Run the car on the dyno with a wideband and examine each of the datapoints at the rpm for the PEvsRPM table.
ie.  at 3600 rpm you have a value of 1.0 (wild example)  and the dyno wideband said your real world afr is 14:1, so you're running a bit lean.
Find 1.0 in the leftmost column and go over to the 14.0 column, the value to use is 18, this should give you the change needed to have a 13:1 AFR.
If running dual widebands and ou see a disparity between the two sides I recommend looking at the average of the two banks.
Hope this helps, Any questions email: cmillard@crutchfield.com
