    Engine cooling fans when A/C is on -- How to change the fan settings??

    2014 E38

    I would like for the fans to come on at a higher/faster speed when the A/C is on.
    what is the best way to accomplish this?

    There is a fan speed vs AC pressure table. Without your tune been posted can't say if it exists on your OS. If you find it, start by moving the values to the left. I use it on mine and ended up moving the values 3 cells to left to help with my interchiller temps.

    My crystal ball is in the shop for a polish and oil change, as soon as it gets back I'll get right on this one.
