For you OP, return to stock fully to pass. That's your penance for not searching.

Just throwing a wrench in the works, the DP fix does not work for me. When I have installed and tried every setting it continues to throw a CEL.
Twice now I have passed emissions by removing the backend flash, JB4 to map 0, clearing codes, and doing an easy half hour drive cycle immediately before going in for testing, WITHOUT a DP fix. Just for kicks I drove around after waiting to see how long it would take for a CEL. Just about 900 miles, I forgot I had the code clearing disabled, so that gave me a bit of a scare until I remembered what I was testing. Good luck OP!

Backend flash has to be removed with dp fix. With a backend flash autoclear isn't necessary, hence why going back to all stock flash files and jb 0 works. I've passed it 2x now
