I am keeping the upstream o2 sensors..Just need to delete the downstream ones.
Not sure what exactly you are working on, but on my 2016 Camaro there are 32 codes that need to be unchecked and set to No Error Reported. Everything to do with 'sensor 2'. Pretty sure all the stuff related to this gets taken down.
This is what I have in my notes
Not in order: P0036 P0037 P0038 P0056 P0057 P0058 P0141 P0161 P0137 P0138 P0157 P0158 P0054 P0060 P013A P013B P013C P013D P013E P013F P014A P014B P0420 P0430 P2096 P2097 P2098 P2099 P2270 P2271 P2272 P2273

You also need to disable the cat efficiency codes
I added my list to my earlier post
Don't forget the cat test and the post o2 sensor test if available in the engine diags exhaust tab. Only older software versions will show those two.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
sorry i forgot to put that im working on a 2016 silverado with a 5.3 in it
i tried to uncheck boxes but it just highlights them..the codes are like in a gray area and are checked.
That's part of the new EPA agreement with HP Tuners. You have to take an online class to get access to those parameters. I'm on the old 4.4.4 and probably wont upgrade unless I have to down the road.
what site is the class on? i really need this done
If you are using a version of HPT that requires the class it's not going to let you disable everything you need to even after completing the class. See post #6.
^ What he said, but... it's at HPTUNERS.COM>RESORCES>EMISSIONS
i wish i had the old version..i tried backing up my laptop but it won't let me
Well, the down side of the older version is it doesn't work with the new hardware as I can't look at any of the new logs or tunes that people post here. But I'm only tuning my car so it's not holding me back.....yet.
You can run multiple versions on your computer.
There's a thread on it somewhere.
I think you rename the first install folder then install the second.
Thanks, I'll look into it.
I took the test and got "Certified" and then upgraded to the latest Beta and I could disable all my downstream O2 codes.
2017 Camaro SS, Flow Tech axle back, Roto Fab, Nick Williams 103 TB, BBK long tube headers, Magnuson 2650, Snow Performance Water/Methanol Injection.
I did the same thing..thanks for info everyone.
