I have my elevated idle tuned on my truck and it has yet to turn on this year as well. Most of the time its cranked in the garage but a few times at work it hasn't come one. Been waiting for it to get colder and park it outside for the night to see if it works.
mines kicked on at least a half dozen times already.
