idk know if this is the right forum to post on but oh well. Im stilling in the learning stages of performance products. was wondering i have seen guys with out cats or had cuts outs but somehow tricked the computer to read good emmission or he used o2 sensor dummies. im not sure any help would be appreciated.

 

switching them to 3- no error reported should suffice just make sure you only turn off the second sensors i think there are only like 6 or 8 dtcs

 

will this also clear on computer emmisions test?

 

Also make sure that the readiness monitor flag is set to "ready" before you disable the code. Otherwise you will not pass a obd scan emission test.
