Hello, I have recently started using FBC Better Diesel catalyst....seems to have greatly reduced my soot levels on my iDash. However my Regen % has not followed the soot levels as it did prior
to using FBC. What is the Regen % showing that is filling up the DPF if it is not soot?? I am doing regens when the soot level is showing only 20-25% load.
Any one having a similar experience??

2019 PS 6.7 DPF Soot Level % vs. Regen %
thanks for the reply…. I’m probably not even at 200 miles by the time regen = 100%. But I’m doing local driving not much on the freeway. Usually the soot level has to reach 100 as well as RG in order to trigger…. I have the inhibit on so I can control it manually….. I don’t know what else would make it trigger if soot equals only 25%

I started using Pittsburgh Power's rebranded Better Diesel, Max Mileage a few years ago but now use it with their Flashpoint additive in their recommended dose of 40% MM to 60% FP in a 16 Oz bottle.
Your local stop and go routine is why you're out that short for a regen because EGTs are not hot enough... I daily drive mine, unloaded, but my saving grace is that I live in the hills south of Buffalo. Truck gets hot on the way home as it climbs. My last regen was about 440 miles out. I do them on the expressway I drive into work and home.

If soot was at 25% and you were close to 500 miles, it gets automatically tripped by the ECM like previously stated). My last one out close 500 miles (498 miles actually) with 80% soot load (on truck). I use an iDash to monitor regens and other PIDs.

And less EGR means less soot into the intake and less soot into the particulate filter than say my Gen truck. This is my opinion of course but I could be wrong.
You 23 plus guys have way shorter regens and keep the fuel out of the oil...

The DPF Soot Level on the iDash never matches the DPF% on my dash menu. My only guess is that they monitor different PIDs or calculate differently on the value. I figure as long as neither hits 100, all is good. I really only pay attention to the DPF RG so that when it hits 100, I take it out for a drive until the regen fully completes.

Either get to dealer - or 3rd party that will enable dash functionality or spend for the iDash or both.
imo it is a must to know when the process is about to begin so you can do all you can to ensure an uninterrupted regen process.

My 24 does ecm commanded regens and they are freaking fast, HOT and at some strange interval
my normal weekly drive the dpf hangs at 30 to 45%
And the ten miles at 70 usually gets it back down to 20 by time i get to my neighborhood
but the regens truck decides to do
Wow
Idle bumps up and the smell of HOT HOT
creeps into cabin
Oil temps go up about 8 degrees
Not sure why, maybe from increased under truck temperature
If you let off throttle as in pulling into a parking lot, the idles stays up between 800 and 1k
and dpf clicks down post haste
I have seen less than 10 minutes from 45% to zero
it will also do it on my 1.8 mile 25 mph drive from main road, through my neighborhood to my house, it also will stay in 3rd vice up shift to 6.
Vastly improved over my 21 6.7
the heat does get my attention though
