    LS2 fans.

    Anyone figured out how the fan control scheme works on an LS2 A4? I can't figure it out. The lowest setting is 192, but if I put anthing over 30 in there the fan runs as soon as you start the car, even if the ECT is 75 degrees at startup. What I want to do is make it turn on at 180 and off at 175. Turn both on at 185. Can't figure it out.

    A fix or just tell me what the damn thing is thinking. It makes no sense from what I've played with so far.

    Thanks in advance Chris!!!

    only 2bar changes the fan axis lower.

    For Discrete (relay based) fans the State vs. Desired % and the Output vs. State control when and how many fans come on for a given %.

    Simply look up the State in the State vs. Desired % and then look at which fans are set to come on for a particular state.
