I was able to find some details here that allowed me to add a custom PID to the Torque Pro app, and see the entire regen. The PID was Soot %.
The value is 0-100 percent. I am running an OBDLink MX+ with Torque Pro for reference.
Once I got it set up, i was seeing about 85% Soot a couple days ago. Today while doing some interstate driving, I hit 100% about 5 min from my destination.
As soon as the soot value hit 100, I saw the EGT temps start to climb. It went from @ 650-700, to 1100-1200.
As I got to my destination, and was going slow through the parking lot, I could smell the hot exhaust and an odd odor. Not very strong, but noticeable.
I parked and tried to wait for the regen to finish. It appeared it stopped, as the EGT temps started dropping, but the Soot number was still at 100%.
I shut the truck down.
About 1 hour later I started the truck and drove around and the Soot was still at 100% and the EGT got back up to 1100-1200 degrees. So apparently, when I parked and idled, the regen stopped, but wasn't finished.
This regen lasted for about 15 min, then the soot value dropped to about 1% and the EGT temps dropped to normal ranges.
Now that I know this I will grab the data and plot it. Plus, I reset my trip meter to see how many miles until the next one.
Thought some might be interested in this, as the Torque Pro PID's I have found here don't all work with the LZO engine. I tried Regen distance and Regen state, and they did not work on my 2023. (I used this thread: https://gm1500diesel.com/forum/threads/engine-monitor.90/ ) The DPF Soot did work.
