did longtubes and hi flows and deleted the rear o2s, before first start i uploaded a tune that had every bank X sensor 2 code in the list set to no error no ses. still somehow it set permanent codes for bXs2 heater and circuit causing it to incomplete the o2 sensor monitor (no cel but still wont past obd smog due to monitor). how do i get rid of these stupid codes? i dont have rear bungs to put them in and i dont want to pull the exhaust apart again just to add them. do i have to plug the sensors in and ziptie them under the car or something? do i have to reenable those codes to make the computer check for them then disable again once it clears the codes?
