    If your not satisfied with the 1000rpm idle fix, and can't find an answer in the tune, you may want to look into getting a PWM (Pulse Width Modulated) efan controller to avoid the giant electrical hit when you turn on the AC... I run one from here: http://www.dccontrol.com/

    Make him put your tune back right and do this :


    It will up the idle and all the timing correctly at idle and all driving speeds. Pay close attention to the PCM hook ups. Those need to all be accurate and correct for this to work. If exactly like the diagram pcm side you're good to go. You can disregard the fan wiring if you already have that taken care of. Be sure to ground pin 55 Red

    Can you explain the rocker switch to me? what is its purpose? Wouldn't you want to use the AC command relay ground to activate a relay instead?

    The rocker switch is for a fan override. If you do not want, then you can ignore that part.

    Thank you very much for this. I will have to get some pins and give it a try. Also I like the idea of having an LED on the dash to let me know the fans are on.
