Remember I’m not and expert, so below for starters, they are what I believe are close and relative to give me at least an idea. If you find this confusing then let me know and maybe I hope I can explain it a little better. I have made other custom PIDs that I believe are helpful to maybe only me and some I’m still testing. I’ve been doing this for self interest so I most likely have made some typos below?
EGTs. – My 2013 6.7L has 4 EGTs. I monitor EGT12 which is the post catalyst which gives tells me that the truck is in Active Regen if it goes over 1150 degrees.

FYI: I set some of the Max Values at 400 so that normal readings will show the needle at the top of the gauge which makes it easier for me to just glance at the screen if the needle is at the top of the screen, all is normal. For Example the ECT, EOT and TFT normally run around 200 degrees so that all those gauges should be pointing to the top?
