Will I pass emissions with rear o2's turned off with x-cal2

  • Sponsors (?)


I'm in Tennessee and I have emissions coming up. Just a obdII hook up but I have a x-cal2 program running with the rear o2's turned off cause of my catted x-pipe.

Am I gonna have problems?

Thanks
Josh

Ive passed for 2 years, dont worry.........the last time I got smogged the guy checked underneath using the mirror and he still passed me:lol: These guys dont know their arse from a hole in the ground:D
 
The rear 02 sensors are there to monitor catalytic converter function only. If they are shut off in the tune then there will be no emissions 'hit' by leaving them off. If they are physically not there or the cats are gone, you may not pass a visual inspection, if they do a visual where you live.
