Since i have been watching regens via forscan app my regens are starting with dpf only 40-45%, anyone experience anything similar?

Twice in the same tank of fuel, once going south on a 7 hour drive and again headed back north, no idling running 70-80 mph

Also my app never shows the regen as "on"

I can tell by egt and timing

Since i have had truck i do one regen per tank


Anyone else experienced this or have some input?



Screen shot showing it took it all the way to 0, which it did last time
Am i looking at the right pid?

 

If the regen gauge never reads "on", how confident can you be that the dpf reading is accurate?

 

There are two DPF soot load PIDs that I've seen with the FORscan app. One climbs into the 40%+ or so before the regen starts, while the other is a bit more relative to a true percentage as we think of it, starting regens as the load climbs into the 90 percentile. You might try switching the PIDs so it makes more sense when you look at it.

My understanding is that the PID for regen status hasn't been updated in these apps yet and is thus not reading correctly. Eventually the programers will figure out with PID values will indicate regen on/off.

Thank you all

 

I do not have the forscan app/ but just for reference I have at least one active regen per tank and many times 2 or so it seams. I have had the truck do what I think is a passive regen as well, with no change to fuel usage, but I could smell it. I do a combined of city and country driving. Even on the freeway, its stop and go, and if its not that then it county roads with other challenges. I was sensitive to this regen thing when I got the 2017 F250 as its my first diesel, but now I just drive the dam thing. If it regens it regens, and if I have to shut if off because I at my location and I think its still in regen, I shut if off and figure it will start up again when it needs to. I figure its got enough sensors it know what its doing and having this app would only make me wonder about things I have no way of fixing. I love the truck and its just great to drive. I have noticed that using different brands of diesel seams to change the amount of regens I get too.

 

I Think the top right one is the correct one
We will see

I agree natpark
The regens are frustrating to me
Every diesel i have had before this one (7 pickups) did not have this crap

The waste of fuel is frustrating when you see your mpg start dropping

 

I don't know about the lastest model year but I mostly tow with mine and therefore very little regens.

 

Unfortunately there's not a lot we can do about it all of these new generation diesels have them. I have been dealing with them since 2008 I fought it at first with a complete delete kit but since that truck performed even worse than stock I have left the rest of them all stock.
I just stopped looking at the regen cycles and excepted the fuel compromise
The only problem I really have is that my 2014 is mostly an in town truck and I always get exhaust system full please drive to clean this is quite annoying I have already had to replace the EGR once on this truck
I think my next daily driver will be a gasser

 

Correct me if I'm wrong, but heavy towing=more soot therefore more regens.

 

heavy towing is more heat for passive regens. You use more def.


Non towing is less heat so the soot builds more and then the need for active regens, less def is used though.

 

Not on my 2011 the heavier the least amount of regens
I think it would be hot enough to do active regen without forcing a regen
Sorry passive not active

 

Isnt an active regen still a regen though? I guess you guys are just referring to regens that require extra fuel?

 

Correct when you're pulling heavy the exhaust system is hot enough that it does not require to go into a full regen with extra fuel being added

 

Trying to keep from tequila tune as long as i can
Its getting harder

 

Is it weird I just haven't noticed one yet... ran thru a full tank... I've had the truck about 2 weeks... guess I didn't even pay attention. The truck is lifted so I just accepted crappie mpg's as the normal...I've steadily been between 10-12 in town driving around.
