Fan_1_coolant_temp and number two are the lines being changed. As for fan one or two coming on, both the left and right fans kick on right at 212* ferenheight per my Torque app. The fans are a high low set up not a left and right set up, right? I just want to be sure I'm expecting to see/feel the right stimuli.I was advised to try to type in my VIN as the guy had some issue similar to mine in the past and manually entering helped. I sure hope it does. The last thing I want is to be stuck with one tune for EVERY situation/season.
