To clarify what @
Koa said:
1) Your OFT is "married" to the car whenever you flash a tune.
2) The OFT can clear CELs
3) However, to prevent the CEL from coming back, you must flash an OFT tune that specifically disables that CEL code.
4) To unmarry your OFT, you have to flash back to stock.
So I would actually disagree with @
Koa and say that, for a long term solution, your answers are yes and yes.
Edit: If you have a CEL from an O2 sensor issue, it means you have a catless header, yes? If that's the case, you should really get a tune anyways, either through OFT or ECUtek.
