I have emissions coming up in maryland for my 2005 Saleen mustang., my current tune has the 02s turned off. My car used to throw a code "System readyness incomplete " Since the 02s were off. But it hasn't thrown a code in about 3 months. Do you think it will pass the OBD 2 scan? all it does is check for trouble codes. My cel is not on now. Since it threw a "System not Ready" Code about 3 months ago is it in the systems memory and will the emission reader pick the code up from history>? thanks. And is there a way to turn the 02s back on besides using a tuner. And my buddy will let me use his tuner to turn on my 02s as long as it won't lock the VIN to my car. Will it lock the vin just for using it to turn 02s on.
