roughly 10 values equates to 1 full air fuel ratio. Example, if your values were 130 and you were 13:1 but wanted to be at 12:1 you would add 10 making your value 140.
In the upper right of our software, you will see a box with the number 1 in there. You can type whatever value there, and up and down buttons beside that will nudge the selected map value(s) by that amount per click.
If you are running 15:1 in boost, find out at what RPM you start making boost and going lean, and add 35 values to the numbers from that RPM and up. In terms of load, add start at said RPM and go from the fourth or fifth column to the end.
You won't hurt it if you add lots of fuel and then work to take it away.
