I tried the pedal commander. While it seemed to increase throttle response at first, I realized it really wasn't much different when i floored the pedal. Still slow to go but then made the truck a bit squirrelly.
I am saving up for a GDE hot tune,I’m going to give that a try.

I have the GDE hot tune and it has been AMAZING! No lag and MUCH better MPG. 15.3mpg in town before the tune to just over 20.

Regeneration is the term used to describe cleaning of the DPF
Diesel particulate filter
A diesel particulate filter (or DPF) is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and under certain conditions can attain soot removal efficiencies approaching 100%. Some filters are single-use, intended for disposal an…

. During this process the ‘wet and sooty’ particulate matter is subjected to further combustion inside the DPF itself. Surface temperatures inside the DPF can exceed 600 Degrees Celsius
Degree Celsius
Celsius, historically known as centigrade, is a scale and unit of measurement for temperature. As an SI derived unit, it is used by most countries in the world. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale.

, at which point the soot turns into a hot white ash.

What's a regen?
Regenerations (self Cleaning) of the Diesel Particulate Filter (DPF)

Active (self-regeneration) = fuel is injected into the exhaust stroke strictly for the purpose of increasing exhaust gas temperatures (EGT's) to get to the temperature necessary to oxidize the carbon and burn the soot out of the diesel particulate filter (DPF). The DPF will get near 1200 degrees

Your truck will regenerate (active) when the DPF soot level reaches 65%. This will likely occur every 100-300 miles. You will only see the notice on the EVIC if the soot level reaches 80-90% due to uncompleted regens.

The stock tuning assumes that there is some small amount of residual soot and resets to that value (approx 9%) when the Active regen has run for the complete time duration.

--------------------------------------------------------------------

Passive = the engine is working hard enough that the EGT's are hot enough to keep the regeneration of the DPF in process. There is no extra fuel burned.

Generally the EGT’s will not get hot enough for a passive regeneration at unloaded highway speeds. The EGT’s can reach passive temps when towing, carrying a full load, or driving hard.

Hasn't happened to me. but after the AEM update if I open my door while in drive or reverse. It stops moving and wont move again until I shut the door and put it in park then into gear.
Same here. I noticed that after the tune as well. I some times open the door up when i am backing up my trailer to see what is around me. I did that after the tune and the truck stopped. same issue.

FCA sucks. i do love the truck but they had to f with it. Not sure if i would buy another American car after this issue. I bought American because it is the right thing to do as a patriot. If they do not make this right i am done.

I'm pretty sure that's a whole different recall (see U53 I think?). They may have done it at the same time as the AEM. It's supposed to save people from themselves. It puts the vehicle into park so you don't fall out and run yourself over.....Check to see if your seat belt is fastened when it occurs. I've read that a work-around is to simply connect the seat belt behind your back when/if you need to back up with the door open but I'm not 100% sure.

U07 Recall - 8 speed rotary shifter
John,
I believe it's the U074 Auto Park safety recall. It was a separate recall but has been canceled and incorporated with the AEM flash. We think too many were declining the U74 which leaves a giant liability problem as there has been death where a person got out of the truck while backing and truck rolled over him. So FCA made it part of the AEM where it can't be declined.

John,
Sorry, brain fart, yes, it is the U07 (U74 is tailgate fix).
Interesting that you still have it listed separately. My 2016 was listed separately, then removed and the dealer didn't know why. Since then several people getting the AEM have reported (unhappily) that it was part of the AEM. One reporter thought his tranny was failing, had no idea about the U07. Many of us have assumed it was incorporated with the AEM. I am waiting until the end to get the AEM so I cannot say.
FCA sure knows how to keep me confused.

I'm puzzled too. The recall notice for my truck on the Ram site went away for a while and now it's back.
