    E38 Rear O2 and Cat delete

    Are there any extra steps needed to delete cats and rear O2s?

    2012 Camaro SS 6.2L E38 I believe.

    They keep causing check engine light and DTCs in the scanner.

    I have attached some an image of what I'm seeing. The thing I've never seen before is the permanent thats there.

    What am I missing?

    Thanks everyone.

    Permanent codes do not clear, it's why they are permanent.

    You can disable the DTC"s by setting them to no error reported and disable the SES light but it will always show up as a permanent DTC. Sometimes some of them go away after tons of drive cycles.

    You also need to disable the cat test and post o2 sensor test within the tune when you delete those parts.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
