Added an NGauge and tune a few weeks ago and been looking at different pids. I’m trying to understand when I’m actual in Regen but I’m not sure I even know which ones would help me with that. But I am thinking 150 miles average for Regen is pretty dang often??! (2017 f250)
Your regens will depend on many factors, driving habits, idle time, stop and go traffic vs. highway driving, cetane rating of diesel fuel, etc, etc. The more the truck heats up on longer rides the less regens you will have. The more stop and go and idling, the more frequent the regens. The higher the cetane, the cleaner the burn, so less soot created in the DPF.

that makes since as my driving habits are similar to that. 20-30 minute drive intervals throughout the day. Some highway some back roads. Here and there will be in the truck at idle for 10 minutes or so on a job site.
anything I can do to help with this or it is what it is? Just seems Regen so frequent is killing fuel mileage for nothing.

It is what it is. I regen about every 150 miles. I can't change the way I use the truck so it will be that way unless I delete and tune the regen out. There are strategies you can use that will shorten the regen time, but you have to be right in that situation. It's frequently more trouble than it's worth. I've learned to just live with it and let it do what it's going to do.
How can I tell when the Regen starts it is going on. I e been watching the soot screen the last few days. Works it’s way up to 100then starts over and so on. I assume around 100 and starts over it did a Regen?
Isn't that PID telling you it takes 150 miles to do a full REGEN and not 150 miles between regens? That particular PID on mine was saying average 13.XXmiles and my last regen took 30 miles to complete and now that PID says 30.XX...
I notice a lot of people have a DEF % screen turned on and watch that and want it to get down to as close as 0% as possible showing Regen was most successful.
from the three PID screens on my nDash I posted related to DEF, is one of them the same as the DEF% screen to watch and see how efficient my regens are?

Im actually not sure and may be wrong then? When I first got the tune and gauge about 3 weeks ago it said average was 285 miles. I just went back to the screen 3 days to see what it was at and that’s when I noticed it was at 150 and has been on that since I noticed it 3 days ago.
If it's an average, then it probably won't change until the next regen. Thinking out loud here... How many intervals between regens can it keep track of? Memory in these systems isn't large, there's no hard drive to store data on so it has to be in memory. The system may keep track of the last (throwing out a number here) 20 intervals between regens. Therefore, it's a rolling average. If regen 21 (the oldest) was 500 miles and all the rest were 100 miles then your average is going to decrease quite a bit (by 20) once regen 21 rolls off. This is all pure speculation based on my 30 years of software development, none of which has been used on vehicles.

I would agree with that... in my example it said 13+ and I watched as my current regen on the highway was going on and it updated after it was complete and nearly matched what I observed.
It's hard sometimes to change your driving habits, but something you can do is look for top tier diesel fuel or sometimes called premium diesel. It has an additive package that raises cetane and provides added lubricity among other benefits. I've noticed a difference in regens between biodiesel and straight diesel. Biodoesel burns a bit cleaner and with a good additive will help extend time between regens. I also run Stanadyne fuel treatment and an extra splash of lubricity only additive for safe measure. The cleanest burn possible is key to extending the periods between regens. And less idle time if possible.
