Has anyone deleted the rear 02 sensors from there computer and had any problems going through emissions? Would they know you deleted them when they hook up the OBDII?

They do a scan. No codes means you pass. I have actually deleted codes drove to the test, passed and the codes reset on the way home. O2 codes but I can't imagine any other code raising suspicion.

Depends on the codes. I believe that you have to have some certain readiness monitors passed, o2 (cat test) included.

Yea thats what i was thinking. Changing or deleting the 02 sensors in the computer would make the readiness not there, making it show them theres something wrong with the 02 sensors.
Anyone tried these?

Not sure what software you are using but with TunerCat, I can delete the the o2 DTCs and I can get all the o2 readiness flags set to ready.
