The past few days I've noticed higher than normal idle speed. I've been driving only in town recently, and the truck smells 'hot' when I park it, and the cooling fan runs for a while after shutdown. My thought is that the truck is doing a regen, and is not completing. Is this a valid assumption - higher idle indicates a regen? It seems to have healed itself after a short drive this morning.

With a GDE tune the fans will run after shutdown if shut off during a regen.

Does that explain the 900 rpm idle as well?

Been tuned since March '17. I recently had to shut the motor off during regen because it popped up a mile and half from work. The fans didn't run at all. I hung around the truck for a few remembering the fans were supposed to keep running but nada. Is there a temp threshold or is it as simple as just being in regen?

There is a temp threshold for the fans.
