6.6 regens

[zrteton]

So far I've seen 582 and 643 mi between regens according to the iDash.

Mixed driving, with some shorter trips to town and highway driving. No heavy towing yet.

What are you seeing?

These things regen based on 4 trigger values

Time, engine hours
Fuel used
Miles
DPF soot load

Whichever gets it to the trigger first wins, but the 6.6 is rated at a maximum of about 800 miles before a regen if no other parameters trigger it first.
