so what your saying is that you cant pass emissions because your tune is causing the OBII test to show up "not ready"? How did you install the tune? Do you not have the hand held? I don't think that tunes would trigger any OBII problem. Do you have a check engine light on?

if the tune is on a flasher then you can just re-install the factory tune which should have been saved in the tuner. If you had a guy professionaly tune it then that shouldnt throw any codes. MILS eliminators either work or they dont. There is no way of getting around those. Even if you clear the codes they will come back on and stay in memory. So when they do the OBDII you will still fail because they will be in memory.

Because MILS trick the computer into thinking there are cats on the car. When you hook an OBDII test up it checks your storage and current codes to make sure there are no problems.... So if you can fool your car computer then you will beat the OBDII test and pass with flying colors. But if the MILS arent working well with your car and giving you a check engine then your screwed
