I live in NC and a local GenCoupe group here is trying to get BTR to come down and do a tune day. I plan on going and finally getting my car tuned. Anyway today I ordered an O2 housing for my car and had a question about the CEL code. I know the code will come on and that they can turn it off too. However I still need my car to pass inspection. My question is if they turn the CEL off and I put my stock O2 housing in just for inspection (no code coming on) if it will pass inspection? Do they tune it to where the light on the dash is just off for that code or make it to where the code will show “not ready” even if I have my stock housing in and no actual code is being thrown.
