Me and my boss specialize in getting cars to pass etest lol. First and foremost your allowed to have 1 monitor not ready, as long as its not the cat or o2 sensors, IIRC. We've done double spark plug anti fouler on an audi A4 (drill out one and screw them both together). If you have EVAP issues, most systems wont do an EVAP check if your over 3/4 tank or under 1/4. There was a thread somewhere how to make your own electronic O2 cheater, but i dont remember were i saw it :S.
