I have a long list of codes after installing longtubes. My car is a 2022 and I was told that a hptuners update may be required for my rear o2 sensors to be fully deactivated. I'm still puzzled as to all of the other codes listed. Any help is greatly appreciated.

If you installed headers, you will need a tune. Also that will void your warranty.


Do you have a list of the codes? I'm going to guess they all are going to be about the O2s.

And the car is fbo and I'm going through the remote tuning process now

Hope you’re not in a state that does plug-in emissions testing. You’re going to have permanent codes that will be visible to a plug-in scan.

I’ve said it a million times, but here goes: have your tuner disable cat codes *before* you install headers! Once the code is set, only the car verifying the issue is fixed will make the code go away.

Your tuner can shut off the CEL at least. And if you do not have plug in emissions, that should get you by.

^Yup

Anytime you remove emission related stuff from these cars you need to delete the codes before ever starting the car. Now you have permanent codes that will never go away. You won't have a light on the Dash but they are stored in the ECU until you put the emission stuff back on the car and it passes it's test.
