    i would look for a stock tune of a truck that had E-fans and compare maybe fine tune a little to your liking

    If you are running a cooler thermostat you can set the temps cooler by a similar amount.

    Open the VCM editor and press the F1 key. Click "working with VCM editor", Click on "Parameters-GM", click on "Systems", click on "Fans".

    Oops nevermind, they didn't bother to give info on that. They did define what on and off means good thing I would have never figured that one out.

    Well go to the repository and download a 2005 Tahoe, they have electric fans.

    So are your fans the normal on/off type?
    Or are they variable speed controlled by a pulse width modulated signal?

    Probably the traditional style fans I would assume.

    My guess is recirculation fitted = fan#2. Type fitted = analog.
    This is what I have my 2002 silverado pcm thats in my s10 set up. Two speed fans, they both work with these settings, it has no a/c.
