My truck seldom sees anything below 25 degrees. I dont sleep in it so I dont idle it

9 minutes or 9 miles accomplishes it, either way, but mid 20s below zero is as cold as I've seen with this truck and not much of that.
They aren't all like this, and I have heard of guys not idling never having to do a forced regen with a DD engine.
I idle alot, it's necessary at times. The harness was updated. That helped the check engine lights issue. -
Only about 60% loaded miles.
It only ever requests a parked Regen if I’m idling overnight, even on the coldest days it never requests a parked Regen.But since I have that AutoElevate parameter set, it just does it itself at night
I have a Scangauge (not KR) set to monitor NOx and DPF outlet temperature. In the winter it almost daily does a driving Regen of just under 1,000 degrees for a very short duration, definitely under three minutes.
Once a week and sometimes twice it will do a longer, lower temperature Regen of just under 800 degrees for 2-1/2 hours while running down the road, if I happen to stop , it will resume that one when I get going again.
Then about once a month it will do a hot Regen while driving for about 20 minutes gradually getting hotter, peaking out at 1,120 degrees.
In the summer it never does the hot one, I might see the short under 1,000 Regen once in three weeks. The long one never in the summer.mhyn, Hammer166, 25(2)+2 and 1 other person Thank this. -
