I've got a few Dodges coming back recently failing emissions for system not ready. Not codes that I'm aware of, just system not ready failures. My first thought is they have weak batteries. Is there anything I should be looking at in the tune to make sure everything is set?
no one has any suggestions? Do you need to turn off the rear o2s from effecting the closed loop?
VVT disabled/limited not allowing EGR to complete? My car had a cam installed and that is one the other is the long tube headers, I shut off the error for the rear o2 sensors as I messed with the transportation delay a few times and just got sick of the code so it was easier to shut them off. I do not have emissions in my area.
I am not the guy that tunes transmissions, our username is similar. If yo message me about I am not replying anymore.
