Just an update... It is called the "Stay Warm" feature in the programming. it is part of the 'Soot Filter Reduction' manager and the 'Emissions auXiliary reduction Manager' systems in the ecm. It essentially will extend the regen cycle and keep it active at low speeds for up to 10 minutes (then it times out) if it is in a regen and you slow down.

I would imagine this would consume more fuel, dumping it into the exhaust to keep the system hot while it is in this state. Guess it would be a trade-off of possibly more complete regen cycle on trucks that stop/go a lot at the expense of some extra fuel ... for up to 10 minutes before cancelling the regen cycle. -- just speculation based on what I have seen of it behind the scenes in the ecm programming.
