Can you turn off the rear o2s? a buddy says you cant?
Well he has a 402 ls2 motor making 500rwhp, however when he got the car tuned, the guy tuned it with his hp tuners software and he still throws the code for the rear o2 sensors, the tuner said he needs o2 sims and he cant tune them out? I swear that you could and if you can, how do you tune them out, he told me if you tune them out, and after a some cycles if the computer doesnt see it, it throws a code for the rear o2s? Who is right? Me or him? It would be annoying as hell to drive around with a engine light on all the time!

Yet another answer for yes. This guy obviously isn't very good with tuning with HPTuners. See below....

Go to Edit>Engine Diagnostic’s>DTC’s>Error Mode = 3 for each of the codes above.
Go to Edit>Engine Diagnostic’s>DTC’s>SES Enabled = Off for each of the codes above.
