There are tunes that will remove the check engine light but it will not alter the ready flags. I believe your allowed to have 1 not ready flag. That's what I had during my last emissions and I passed. There is a member on m5board (sailor24) that rigged up something to fix the carbon build up issue. Ill try and find the link.
