    Default E38 cooling fan runs all the time

    I have a 67 camaro with a LS3 and a single 12v fan on a relay. Did the fan patch and set the on/off values to what I found here on the forum. Still can't seem to get it figured out. Here is the tune file. Any help is appreciated!

    Also it has a corvette calibration in it, from what I'm reading it needs to be switched from PWM to Relay control. Does anyone know how to do that?
