Going to be buying my tuning stuff soon,and wanted to start learning and looking over stuff now. I was looking over the $42 bin file from this site for a 1227747, and saw both: RPM added to desired idle w/AC on, & RPM added for A/C On. The first has a value of 0, and the second has a value of 25. Why are there two different settings? Do they both need adjusted in some way, or is just the second necessary?
I want to raise the rpms with the a/c on because it makes the a/c work better, and during the summer here in Vegas, the colder the a/c the better.
