I don't know anyone that pulls into a camp ground hot. It's slow moving and with the iDash you have a ton of warning. Of course it's possible to pull in while doing a regen, but unlikely it will be a surprise if you have an iDash unless you just were not looking at your DPF Reg %. That's on the driver. It's usually a mile or a few of slow driving, check-in, creeping to your site. I was just making a point that drive it and quit worrying about regens. They are a lot better than the OG's. I deleted 3 trucks (2 Powerstrokes and a Cummins) before my '20 and my '22 due to regen/emission/sensor issues. They are much better (knocks on wood). This is just my opinion of course. It's YOUR truck and you can operate it however you want

 

^^ This. If anything it puts fuel in the oil. Even while sitting idle it is still doing a regen, at least mine does, and I am not going to wait until it finishes and wastes fuel. If I find it creeping up to 100% and I have less than 32 miles, I will wait until my next trip of at least 32 miles before activating it. As long as the iDash doesn't exceed 100%, nothing to worry about. I also never short trip the truck, the engine and trans is always 190+ on every trip, this way my oil lasts longer, and doing regen at highway speeds only helps reduce the amount of fuel that can get into the oil.

 

I simply drive my truck towing or not. When towing or not, I typically know when my truck is regening by the lie o meter like you mention or when driving slow speeds the engine makes a different sound. If I know the truck is in regen when I'm arriving, I simply put it in park which disables the regen process, let it idle for a minute or two and shut the truck off.

 

^^^Works for me^^^

 

Thanks Scott... yes, remember the Unicorn well...

 

Yesterday finished a 1,200 mile move with the 16k 5th wheel over the past 5 days (3 travel days). Experienced 2 regens, 1 on the first travel day, 1 on the 3rd travel day. Last one was over 750+ miles between regens. I suppose towing helps.

 

Could you share a couple of screen shots of which display your using to see this?

 

 

here is what I monitor

 

Thank you guys

 

Just had a recent regen that started not long after I left home, once the oil hit 148 degrees, she went active. When I was coming the down to a stop sign, once off the throttle, the exhaust note is different. I've heard it before. It almost sounds like a mild engine brake sound.

As to shutting down the truck after a regen, I usually complete them while driving the local expressway so I drive at least 20 miles after the regen shuts off, so the truck has time to cool off (especially the DPF). It's not uncommon for me to put on at least 75 miles or close to 100 miles driving the expressway, getting closer to the burb where I work, turn back around and head south again (altitude climbs -- good for getting it hotter), to wait for the truck to go into regen because for me, it's easier to get it done when I have time rather than having one start halfway to work and get there with the DPF 1000 degrees... then I have to idle it to cool it down.

Having an iDash is helpful to me because I daily drive the truck unloaded, so I can stay on top of things to make the DPF last as long as possible. And completing regens, knowing they complete and reading EGTs allows the DPF to properly cool off. I have had the truck in regen when I've arrived at work and let the truck continue to idle in park to bring down those EGTs.

Here's an article from Pittsburgh Power. I run their Max Mileage FBC which is rebranded Better Diesel. They deal with the big trucks but it's still the same fuel and the same emissions components.

That's cool to know... the second coming of the Unicorn... I'd say it's towing for sure.

 

2020 and up have a program in them to regen no matter what or how driven to regen at 496 miles.

But you also can program it to turn off the auto regen thus allowing those further out regens.

It just does not make sense to regen with 0% soot @ 496 just because.

 

Stop bragging already...

 

Does that mean that the newer models don't have a 500 mile regen requirement?
