I appreciate very much the
all the feedback you are giving.

The truly sad part is not only do
I not have a 6.7 but I drive an old
obdi jeep. The only time I get to use
the dashboard is on family and
friends vehicles.

Very grateful for your time and
your sharing. I have learned a lot
just by helping others like yourself.

I wasn’t too far off for the alarm
EGT12 > 600 lol.

Its interesting to note that EGT13
stayed around the ~1000 degrees
we read about. Just didnt realize
that EGT12 would be hotter.

Based upon your startup readings
from before and this data I am
thinking the order is correct. IMHO.

I also believe that the DIA dropped
when you interrupted a regen that
just started and didnt totally reset
until the full regen was completed.

Now if we only had positive and
negative direction edge triggers
we would be set.

I was thinking about that 22017B you
were using earlier might be Fords extended
pid equivalent to the mode 01 pid 7B listed in
wiki for DPF which supposedly returns 7 bytes.

If that is true then maybe your other sensors
can be found in the 220001-220200 pid range
by adding 22 to the mode 01 pids and looking
at the responses.

I listed the EGR Temp above as a trial case to
see if it would respond with meaningful data.
(22016B).

I hope I didnt confuse you and Bronco.

For some reason it wouldn’t let me post the equation for DIS above?

((A < 16)+(B < 8)+C)*0.24 This PID seems to be working. PID – 2216c1 Long Name – Fuel Level Short Name – Fuel Min Value – 0.0 Max Value – 100.0 Scale Factor – x1 Unit Type – % Equation – ((A*256)+B)*(1/38) OBD Header – 7E0

Interesting that 2216c1 matches pid that
was used in 2004 Fords for fuel level.

Thanks for pointing that out. That gives me another Idea; I’ve been trying to find just new PIDs for the 6.7L when I should test some old ones. Of course the ones I really want are the ones for the DPF and they seem to be new LOL.

Still strange that there are 1600 views of this thread and few responding? I’m glad for your help, without you, I’d be a one man band without an instrument.

Since 22116c didnt work I would look
hard at mode 1 pids: 017A and 017B responses
using the equation for dpf psi.

The mode 22 pids: 22017A and 22017B
as well.

I didn’t get a response for 017B, 22017A, 22017B

I did get a response to 017A
Response from Equation -0.73138

I didn’t write down the other command response because I thought it would stay on my phone when I disconnected, but it didn’t. I’ll write it down next time.

We’re all waiting patiently to see if you guys figure out the regen monitoring. I’d gladly help if I had any clue how to program. The most I can offer is information from the service manual (which I’m sure you already have) and information from my own Torque app for testing.

Also watching are the companies that currently offer products that monitor the regens and other DPF parameters through their products. I doubt they’ll chime in with any help.

Thanks Folks:

I too would like to know the Regen Information, I use my truck also as a daily driver and it would be nice to know when it is close to going into a Regen. I hate not completing a Regen and I don’t always see the message that is up for seconds. I also owned a 6.4L and believe that miss completing Regens is hard on the Engine, DPF and MPG.
I don’t have a Service Manual and Capp777 doesn’t own a 6.7, so we are guessing on a lot of things (well me more then him).

The other companies are going to find it hard to reduce its cost against a App. I believe that only one company has a monitor out for a 2013 6.7L and with the EPA rules on Tuners it only makes the information a bigger kept secret.

That said! So that leaves it to us. I’d appreciate you trying the PIDs and letting us know if you are getting the same results. Also if I have left a PID out from my list that you would like, I’ll post it if I believe it is working and worth it. DIS would be helpful info because I think it stops increasing when it starts a Regen and zeros when the Regen completes. EGT12 increases over 1000 degrees a few seconds after the message displays, once I confirm this, I’ll probably set a high limit alarm at 1100 degrees.

I think that the soot level is determined by a threshold of exhaust gas flow rate and the value of the DPF pressure sensor. This value is calculated by the PCM along with other permissive to start a Regen. So just knowing the DPF psi from the sensor isn’t going to really help because giving the engine more throttle is going to increase pressure. The big question to me is if the PCM has a PID that will give this PID out or is it kept internal. I believe that the Dealer can manually start a regen and would do so only if they knew that the DPF needed a good cleaning. I expect the PCM will send out a PID value so they can diagnose a DPF problem.

Capp777:

Could you define variables and what I should try, also equations.
I did create some custom PIDs I’ll try tomorrow. Sample equation – ((A*256)+B)*(1/38)

I noticed that some Icons in the Manage Custom OBD2 PID page are “Current Data” and some are “ECM Custom PID”, do you know what this means?

Would the current data be the mode 1 pid(s)
while the ecu custom pid be your mode 22
pids?

Can you post the test response so I can see
what raw data we are looking at?

A*0.39216 for % (variables A through G?)

((A*256)+B)*(1/13107) for volts

For the dpf psi equation and volts I would try
variables A&B, B&C, C&D… F&G.

Created 5 custom 017a PIDs

DPF 3, 4, 5&6 Showed the same response for second number (7E82-13C000000000000) number after the “-” increased when increasing throttle. DPF 3 unit was psi, the rest %

DPF 3 – Equation (((A*256)+B)*0.000135)0.8005 (Showed -0.7 on gauge)
DPF 4 – Equation ((A*256)+B)*(1/38) (Showed 13.5 on gauge)
DPF 5 – Equation A*0.39216 (Showed 0.8 on gauge)
DPF 6 – Equation B*0.39216 (Showed 0.0 on gauge)

Hope this makes sense, starting to confuse me. Any one knows a Link to explain the basics for formulas. Hoping the developer will add to the Wiki, I’m scared of burning Capp777 out, he is doing all the work.
