Just got it last night and the main reason for getting it was to program the fan to come on earlier for cooling. The options that it gives you for the fan look sketchy. I want to turn the fans on at an ealier temp. Does it work that way? I am at work and only had a brief amount of time to look at the directions. Also what do the different programs in it do for our cars. Did you actually see the "performance program" add power to your car? Looks easy to use just wondering.
