UpRev and O2 sensors?

Hi,

 

My car had the UpRev installed by the previous owner and before I had it the car had De-cat pipes fitted. My question is, when I refit the De-cat pipes will I need to transfer the O2 sensors from the cats or are they usually disabled when flashed?

 

Thanks

From what I understand there are two sensors each side so four, the regular O2 ones which sit before the cat and two that sit after the cat and measure its efficiency , it's these sensors that are troublesome setting off cel lights etc and these are the ones disabled during up rev.

 

So cats or no cats won't make any difference
