When your done with the V-Tune, set your AFR table back to the ORIGINAL, there you will see the AFR table has several values set in the cells at different kPa and rpm break points. 14.6 will be in the closed loop in a low load range, AFR values in the 13's, 14's or even 12's will be in the cells that have a heavier load on them.....if you wanted to add fuel or subtract fuel in these areas you do so by changing the values in the cells.
If you change anything in the 14.6 (RED) area you will take that cell (or cells ) out of closed loop....but lets say you had some decell popping going on, you will want to add some fuel in the 20kPa column to richen the mixture that will eliminate the decell popping. If you want the bike to run cooler at idle a guy can set the 750 rpm to 1250 rpm in the 20 and 30 kPa columns to 13's....point is once the VE tables are synchornized through your V-Tune process any value in the AFR table cells should be what you get or very close to it so now you have control over the AFR to run what you want.

Depending on the bike and the map the closed loop area varys, however, about upo to 80kPa and 750 to 3500rpm would be the average.
