    Need a little help with HP tuners or 2 not ready codes

    got my car back a few weeks ago from cam/head port, valves and switch to HP tuners. Asked the tuner if he was going to disable the rear 02s and he stated he doesn't need to. He can have the range I guess so close that it will semi read and not throw a code. Well next morning after pick up light comes on for P1128 closed fuel loop or something like if memory serves me correct. Send code to tuner and he's never seen nor have I. Go back to shop, seems he's unable to get it to do "what he wants" so he diables the rear 02s and now my car just sits with 2 not readys. Im talking 3 tanks of gas, 400+ miles and nothing.

    Any ideas fellas?

    Thank you,
    Jay Z

    More than one way to disable the rear O2s...what did he do exactly?
    Please don't PM me, I don't always have time to go through them!

    That's extremely strange. I've put close to 2k miles on mine and haven't had an issue with the rear O2's.

    Just max out the temps on the rear o2. They'll report without making any adjustments

    Just txted him for clarity. Under my assumption, he tried to max out temps and didn't work forcing to disable.

    I have since replaced 02s but didn't change anything

    shrug, according to a scan tool with live data, the 02s have voltage so I know their reading

    Even if they are disabled they'll still report voltage. Question is, did he kill the O2 hardware switches, directly disable the related P codes, or raise the threshold for Rear O2 tests?

    He said he's working on a fix and testing since im 2hrs away.... Sooo i'll wait. Cars already 8 months out, what;s another month lol

    Side note... If I purchase my own HP tuner mcjigger, would I be able to retain his tune and modify what I wanted IF i wanted?

    Yes. You can save the tune he put in and alter it if need be.

    Other than the code, how's it running?

    Awesome! Now let me find the best deal on one....

    Great. Almost stock besides the occasional stall in reverse when i'm fully locked. But honestly.... not what i was expecting for a Cam/ported heads/oversized valves

    Put it to you this way, I've already called Geico about a 2012 CTSV quote, Looking into used G35 Sedans for a 5.3 swap with a turbski maybe so yea didn't cure my speed/power addiction

    You'll have to license it to edit it yourself

    I loved me some Gen 2 CTSVs until I got my 13 ATS then sat in a buddys 13 V Wagon. It was like the interiors did not come from the same company. The V2 was squeaking and rattling like my 99 Camaro interior, and materials felt the same. Drove me nuts...and I'm not a big interior guy. That said, the LSA does indeed satisfy certain addictions
    My old Boss had a 13 CTSV...that diff made noises I never heard come from the back of a car before. They replaced it under warranty, but it only took like 30K miles to get to that point. Then there are the blowers that often need to be replaced. Do your homework
