Regen question

I've got roughly 2k miles on my new 6.4. I just got back from a 1200 mile trip I didn't notice a regen yet. The only off thing that has happened is that when I backed off a bit on the throtle after passing on an up hill pass, the engine sputtered or missed a couple of times and then just kept going like nothing happened. I'm wondering if that was a kind of mild passive regen?

We have an 08 ambulance. I'm concerned that in a crowded ER ambulance bay that it's going to damage another ambulance. Quite often they are parked very close together and our 08 regens a lot due to how it gets driven.
We'll see.

FWIW, my dealer has not heard of anything like this... I am glad I found this forum with information about my specific truck, thanks to all.

I don't think light duty trucks should be any different.

regeneration is a product of the epa. The diesels of today in dealing with the soot and particulates in the exhaust, have a diesel particulate filter. This filter will start to get plugged with particulates. The pressure and temperature sensors come into play, telling the pcm to go into "regeneration". The pcm commands the piezo electric injectors to fire on the exhaust stroke creating more heat burning off the particulates. The temperature sensors verify that the regeneration is working. Your vehicle can also go into regen just by amount of drive cycles. There was a video circulating when the 6.4 first debut, showing a truck with an injector broken, dumping raw fuel into the exhaust, creating a flamethrower effect. This started the concerns with excessive heat from the exhaust. While it is hot, one would have to be excessively irresponsible to create a grass fire. Time will tell however, there has been recalibrations issued to fine tune regeneration characteristics, those so far have been very successful.

What brand are you getting and will you post pics after it's installed?
