    Rear O2 wont turn off

    2013 Camaro SS. I put long tubes on and full exhaust. I turned off the rear O2 on bank 1 & 2. I'm still getting codes P0036, P0056, P0140.
    I've tried reflashing the computer thinking it just didn't take. I turned them on, Flashed computer. Then turned them off again. And I am still getting the codes. Could someone help me with this?

    when making a post go advanced and it will allow you to post up your tune. If you only want to shut off rear o2s you only needed bank 2/1 and 2/2. Did you set them to no error reported or no mil second error
