Active regen question...
Alas, I don't have an Edge yet (soon) so I have zero Insight (see what I did there?) into the regen behaviors of the 6.7...
So today, I noticed the DPF regen kick off via the message center and immediately hit traffic (below 35 mph).
Does the PCM call for an Abort Mission and just try again later in that case?
I merged onto a highway a few minutes later and and noticed the instant MPG was sucking for a bit so thought maybe the regen was still going or restarted after the traffic.
Anyway, I really wish Ford would have included more in depth info for folks like us that want it. I'm also a little concerned I'll obsesses over watching the Edge once I pick one up.

Yeah I see what you did there. It does not cancel (anymore).
With the early 2011 job 1 builds I noticed mine would cancel but that went away once we received the 400HP Ford tune or one of the later ones.
I've had so many firmware updates I've lost track.

Low speed will not cancel an active regen, it will only hamper the progress. Higher speed results in more air & fuel being pumped through the exhaust system as well as more heat being generated by working the engine harder. Since fuel is injected on every exhaust stroke during regen, higher RPM causes more fuel being ignited in the DOC and thus more heat being generated to burn the soot out of the DPF.
As previously stated, the regen will not stop until you put the truck in Park. I have watched several cycles complete with the truck stopped but still in Drive. Even if you Park the truck, if you leave the engine running for a few minutes, the soot level continues to diminish because it takes several minutes for the high heat of the active regen to dissipate so the soot will continue to be burned off until the exhaust temperature drops below the minimum required for regen.
