Okay, so I have a high flow cat, which has no angled bung, and it throws P0420. No problem, disable right? Well, 2 years later, it is time for emissions, and since I have it disabled, apparently that means the OBD2 test will never complete, from what I gather.
I think this is also preventing the cat status from going ready too, and I am only allowed 1 monitor to be in the not ready state. My evap is also currently not ready, which is likely my own fault since I disconnected the battery to check on a wheel sensor issue.
So, what are other people doing to deal with this? I just need to know if I need to throw my stock DP on, and go with a stock tune. What a PITA if that is the case, but I'll do that if I need to. There doesn't seem to be the option for "No error reported" like in other ECUs.
