OK, for those with the factory OE brake controller, including those who added it and have the body software updated to allow EVIC settings, I have a few questions.

Do you have different power level settings? I don't mean the typical 0-10 brake control power; I speak of the single axle, tandem axle, etc.?

I have added the factory controller, and it works fine, just no EVIC communications (haven't done the software upgrade), and the controller does everything else. But I have no other settings for type of trailer and number of axles.

So if there are no other settings aside from the 0-10 power level, I see no reason to do the software upgrade. But this controller feels too aggressive on my 7X16 tandem axle enclosed trailer, and I wonder if it is because I can't adjust it without the EVIC part?

Thanks, I think this would be the same for 2011 and probably 2012 guys, too, and 2009 1500s.

Thanks
