    Fans not following table

    Why isn't the fan following the table? Is this typical? Don't remember this with my Corvette.

    I've modified my stock fan table as shown. Fans don't come on until 216*.

    With my stock fan settings it came on a 226*. Following are my modified table and stock table.

    Even when they come on, bases on visual and sound, they are not running as fast as the table indicates. And my fan PID doesn't register fan %.

    Pretty sure the CTS-V has discrete fans, not PWM like your Vette had. So the fans can't be on a specified percentage, they're either ON or OFF.

    From briefly reading the link I just need to drop the factory settings down until I get the desired run times??? I would like to see the fans come on about 210 and off 203. That would be 16* cooler than what my factory settings allow.

    Used the factory values and dropped them down to start at 199 vs. 210. Fans come on at 214 and off about 203. Right about where I was hoping.
