I bought the predator tuner off AmericanMuscle and they told me I could shut the rear O2's off with it. There is no option to do this on the tuner and AM told me I should be able to. If any1 knows how please help me out, maybe theres an update or something but I dont have the PC interface kit. I need to shut off the rear o2's because I'm running and off road H-pipe with no cats and the o2's are triggering my CEL. My tuner is the U7146 I think, Thanks

That can only be done with a custom tune. The EPA will not allow it to be user selectable.

Just figured that out, it appears the EPA took it off the new tuners in 2007 or somthing. Im getting a custom tune monday to shut off the o2's. Stupid EPA!!!

Where are you getting the custom tune from?

You can get a tune from a cmr dealer like me or anyone else that is a cmr dealer. We can email it to you and you upload it to your predator.
