you guys are talking about two different things. the OBD system has to report emissions OK and the shiffer test has to pass. alcohol will make your exhaust gasses cleaner, you can use o2 sims and other electronics to pass the OBD test. Im in talks to start selling o2 + secondary airpump simluators, i'll let you guys know if i can beat the current prices.
