Yeah, while towing the unicorn would passive regen. the soot % on the dash would drop to 0% just as an active regen would.

the soot% on the idash would hover a little higher due to how it reads the information. Can't quite recall what it would read at.

Passive regens unloaded can or would start on that truck around 500F for EGT 4. Loaded heavy I needed them to be around 700-800F for egt 4. Pretty much ran around that with towing consistently.

It would cool down some as the elevation changes but then you have to get back on it and it would just heat right back up.

 

Okay thanks for the clarification, Scott.

So back to what I was talking about... When I had that 16 point drop on the iDash, the truck gauge stayed at 95%. Then when I turned around to head north as the expressway ended and got back on, due to the downhill driving, it shot back up to 111% before it went active. I'm reserving judgement on Max Mileage until I get more time on the road with it.

 

Several weeks ago when coming home from a camping trip (pulling our camper), I noticed my truck showed 55% full when leaving the campground. I don’t recall what the iDash said now, but (like normally) they did not match. It was about a 70ish mile trip home and I noticed along the way that my trucks DPF% was falling, even though my auto regen was turned off. I checked the EGT temps and they were all ranging in the high 600’s to the high 700’s, so I assumed my truck was in passive regen! By the time I got home the truck was down to 5% IIRC. However, the iDash continued to rise the whole time as if it would under normal driving conditions… A few days later the iDash hit 100% and it stayed there until my trucks readout got back to 90%. At which time I went driving, re-enabled the auto regen and the truck regen-ed back to 0%. The iDash only made it to 17%. Now they are climbing again and are pretty close… the truck is at 60% and the iDash is at 69%. So I’ll see what happens with my next regen.

But I have gotten to where I just don’t pay the iDash DPF% any mind and pay attention to the DPF status and the EGT temps. I prefer to use the DPF% on the truck and go by that.

 

Yeah I don't use the iDash soot load gauge to know when the truck goes into regen. I look for the 100% on the truck gauge or when I am getting out close to 500 miles.

My last regen was the first one where the iDash went to 0% as it usually doesn't before the active regen shuts off. But it usually always passively burns down to 0.0 when I am driving for the cool down period and EGT4 stays hot for awhile.

How many miles out was that regen?

 

My recent trip out with the camper with a really strong head wind the truck was in a passive regen the entire 400 mile trip EGTS in the 700-800 range. I was watching the soot load in Torque Pro drop into the teens while the dash on the truck stayed steady at 75% for the most part. I didn't watch the truck gage as often because I was monitoring engine oil and trans temp due to the wind elevating those temps higher than normal.

The truck made an active regen before we arrived at our destination and the dash only dropped to 50% when the regen stopped. This is what really ticks me off about the 500 mile limit because running around unload at camp even though the soot load was at almost 0 the truck was showing 50% and was climbing fast. This scenario means another regen occurs before 500 miles.

 

I am suspecting that the 2017 and newer dont passive regen.

my suspicion is that a re-flash was done to lower exhaust heat .....probably in response to 2017 and newer cracking of DPF honey comb.

would be interested in hearing from 2017 and newer with current re-flash passive or not.

 

I would like to have an idash just to monitor the regen status (on/off) and the EGT, and battery voltage. Stupid truck doesn't display those things.

 

I don't have any way to moniter mine except the dpf gauge in the dash, this year on our Missouri trip, with the new dpf and ford flashed 20E07. I used the same amount of fuel as last year, the same amount of def as last year. climbing the long grades in Arizona and New Mexico I don't get much passive. From Moriarty NM. to south east Missouri and back I never get over 40% dpf full.
my regen ending numbers (apx.)
26898
27423
27963
28500
29080

 

that is towing my 2022 Grand Design 34" 5th wheel full fresh water tank, 60 gallons water in the truck, 4 adults and 2 dogs, running 75 to 78 mph

 

My 2019 passive regens just fine, when I'm towing a trailer and building enough heat. Recently towed 250 miles into a screaming headwind (30 - 40 mph) and was in passive regen the entire way. Returning with a tailwind, not so much...

 

How big of a passive reduction did you see dirt?

 

I still have to have the reflash done but I have other issues to deal with as well; replaced rear camera not working and a bad air pressure module or whatever would cause that.

 

I want to say soot was at 30% when I first looked at it, it ran down to about 12% and held there for the remainder of the trip.

 

So that reduction on the iDash was similar to mine, yours was 18 and mine was 16, and my truck gauge stayed the same also.

 

Since @brokestroke started his Stainless Diesel thread, I've been looking at aftermarket wheels and turbos.

I came across this for the 11 to 14 trucks:

6.7 Retrofit 2011-2014 Upgrades

The video in this link has a lot of info in it.

With that said, check this out. A comparison between the new 20 plus turbos with the 15-19 turbos.
