Take away rear heated O2 sensors

[C5Sweden]

Hello guys My car has become a pure dragcar and therefore I will throw out the cats and was planning to buy O2 sims but can not find them anywhere anymore? I have HP Tuners for tuning but is it possible to remove the rear O2 sensors after the cat in the software and in case YES, how do I do that?? Help would be much appreciated! Best Regards Tommy

Select "engine diag", then "DTC's", then select every line that has "HO2S" AND "sensor 2" (for example P0137). Then just remove "x" from "SES enable" and select "3 no error reported".

Much appreciated, I am from Finland myself as well, orginally from a little village outside Vasa!

Don't forget to DISABLE the "cat overtemp protection" system--should be a one-line entry--enable/disable---this system will richen up the mixture to cool the cats down--when in PE mode it will make the AFR way rich---You may get false triggers with the cats off and deleted--
