    That vehicle probably doesn't have fan speed other than using two fans in series for low (6v per fan) or in parallel for high. What are you actually trying to accomplish?

    Hello

    I'm trying to set the fans to work ahead of time so that the temperature doesn't rise

    And thank you for the quick reply

    THe way I think it works on this one is you set the (desired % vs ECT) for a higher percentage at a lower temperature. This will then be used by (State vs Desired %) which will then be used by (Output control vs State.). If you put in 100% at the temp you want the fans full speed in the first table, I think that will accomplish what you want it to. It's hard for me to say for sure without seeing all of the settings in those tables.

    Missing the (Output control vs State.) table. But just try putting 97 in at whatever temp and up you want the fan to cut on full speed.
