I am currently fighting tons of DOC issues on a certain truck. constantly running into conversion efficiency issues, no matter regen, pulling the filter off, and cleaning, quickly during a week of starts to become clogged. the engine had an inframe done by another shop, which wasn't great from what I have seen, I ended up running overhead again myself and adjusting injectors and so on. truck has a new diff pressure sensor, new get sensors, new 7th injector, and so on. In the Process of Demandating as a last-ditch effort using Calterm 4.7 and insite 8.7. I would like to DM someone familiar with what I am asking. i have a good grasp of calterm and insite. i would rather dm to go into more details.
I sent you a pm and I will definitely help you…. But runnin rough is going to be your best bet for this one. These engines have an ecm like the 870s have and not many people can do them properly. Also if this is in an international product do yourself a favor and invest in a rom boot harness unless you are shipping the ecm. Sometimes we get away with flashing after the abs fuse and instrument cluster is unplugged but international trucks had very shitty data links and the ecm will almost always rom boot. I actually had a cm870 ism brick last week and with insite, calterm, and kess using a rom boot harness on all 3, a nexiq2, nexiq3, in-line 6, and Ktag have not been able to recover it. All because it failed flash halfway through because of the shitty communication.
Just a warning trying to help
