I'm in the same boat. This PID had worked for me in the past but now always shows 100%.

I got the same problem and settings look ok?

I actually got the PID to work again in the Torque app. Did a couple of things so not exactly sure which one "fixed it". I put 01 in the OBD Header field and clicked Reset on the Remember function data field. I haven't tried a custom PID in OBD fusion yet. I used the SAE built-in PID for Regen status and it worked once but then was stuck at ?.

I tied my OBD Fusion to my Dropbox account which makes it easy to import/export. The 2 files you attached worked like a charm, thanks!

I would have never been able to figure out any of those User-Defined PIDs that are in there. I'm comparing some of them to the provided SAE PIDs and I am seeing some difference in readings so I have no clue how the formula's were created but at this point, who cares!

I love being able to see the passive regen with the green circle and active in red (vs what I had that just turned a 0 to 1 ?).

Now I'm debating keeping my old iPhone 6 in the Jeep as a dedicated gauge cluster!

How did you "tie" your OBD Fusion to Dropbox? I only see 1 file. I just got the OBD Bluetooth in the mail this AM.

Thanks! Interestingly OBD Fusion didnt create the file structure under OBD Fusion file in Dropbox so I created an Import folder and extracted the files there. So when I go to import the file on the App I have to select one or the other?
I'm sorry if I'm being difficult; I just want to see my DPF level...again wish this was something Jeep put on the display natively so if it's getting full I can plan on a Active Regen drive while I've got two toddlers with me...

Ok so I got some good results I think:

However what does Avg Dst mean? I cant seem to edit the unit type...AND if I'm reading this correctly my DPF is only 8% (I had an ARegen the night before)...

I'm pretty sure mt DPF level is never correct with Fusion. I've seen it regen and still be 100% for 1000 miles, I've seen it say 0% forever, and the average dist in K's pretty much stays the same.

Looks like you got it up and running.

Avg Dst = average distance between regens, this dashboard was created by someone on the RAM forums that may not have been in the USA hence the metric readings.

Seeing that your DPF% is at 8.6 that tells me you just completed an Active regen, that's the exact value mine always shows after an A.R. completes.

I created a few different dashboards that show turbo inlet and outlet temp along with DPF inlet and outlet temps. During an Active Regen the screen you are using does not seem to show the DPF Temp accurately, on the dashboard I created with separate DPF temps I see the temps in the 1,100 - 1,200 degree F range.

Also regarding what @CrazyCooter mentioned, I can't say I completely agree ... the DPF % on my setup seems very accurate between 8.6-80%. Once you hit 80% and the engine is full warmed up it will typically go into Active regen immediately and show DPF% as 100% until the Active Regen completes.

If you turn the engine off before the AR completes it will remain at 100% until another AR is completed (I'm actually in that situation as of this writing). I was dropping my kid at practice and I'm a coach so I couldn't drive around for another 10 minutes once the AR started.

I haven't figured out the sequence of events that needs to occur before the next AR kicks off, whether it's a certain number of engine starts or what. Since this last one I have driven on the highway at ~78mph for 30 minutes a couple of times and yet the AR won't kick in again (although OBD Fusion shows it in Passive regen the whole time).

So interesting...I'm back at 100% DPF again. Went and drove an hour on the interstate and no AR occurred. Also haven't had the message popup about continuing to drive...

Mine stayed at 100% for about 700 miles during my last roadtrip before doing an active regen. Its been another 750 miles and its showing 42%.

I dont really think the Fusion numbers are 100% accurate all the time. There's no way I could be traveling including through the rockies towing a 4000lb load at 100% full for 600-700 miles! I would have loss of power, codes, heat, something.........

Fusion also says avg regen is 1020-1090 kilos and has since I started watching 15k miles ago.

The OBD Fusion app should simply be relaying information from the PCM, however this is an interesting situation that I've actually been wondering about.

I recently set off on a road trip from CO to TX starting the trip at 74% Soot level. After a few hours of driving at 75mph the soot level came down as low as 20%.

Now that I'm back home making short trips I quickly got back up to 80% and must have missed the Active Regen that kicked off and I'm back at 100%.

Several starts and a couple of 30 minute highway drives and still no AR, however those 30 minute drives at 75-80mph should definitely burn some soot but I've never seen OBD Fusion change from 100% without an AR...

So yours is a good example of driving that should definitely burn soot considering you probably had EGT above 1,000°F for extended periods which should get DPF temps up to 800+ (plenty hot enough to passively regen). The question is does the computer continue to report 100% no matter what until an AR kicks off?

I don't know, however OBD Fusion will definitely tell you when the DPF temps are high enough to passively regen or when an Active regen is occuring. I would be curious to see if a Scangauge showed the same information but I don't think you can run them both at the same time.
