Unfortunately no. However ones that are being produced from May until whenever they start doing the 22s, they remove the start and stop feature. But I’m not sure if they’re gonna put it back on the 22s if they get more chips.

Not entirely accurate. The question was about the Duramax... and the Duramax continues to be manufactured with start/stop. Only the 5.3 and 6.2 had it removed.

Correct.... Personally, I know this really irks some people, but really its pretty simple to just poke the button upon startup. At least its conveniently located and not buried in the infotainment system.... while I don't necessarily like it, I'm not going to screw with it to disable it....

Yes. Correct. Sorry I totally forgot that it said diesel. Lol. I was actually thinking the five point do your 6.2 engines.

well if there is a button to press after you start it then theoretically you could wire a relay to that button then you wouldn't need to worry about pressing the button anymore.
but until someone de-crypts the software to tune these then there is probably no other reasonable solution.

I ordered and installed this today. Fairly simple install following a video on their site. Works like a charm so far. I have only driven up.down street to test so no long term driving, but so far so good. Definitely recommend.

Interesting thanks for sharing. I might consider this wish it was also DFM. I guess there is a difference pluging in behind there vs the OBDII port???

Actually there is a way.

I have a 2021 Tahoe Premier, not the diesel, and I posted a question here, and asked the dealer. both came back as no's.

However, I found autostopstarteliminator.com, and purchased one of these.
I am happy to report it is easy to do, took 10 more minutes than the video showed, and it work perfectly.
I have no affiliation to this company, and no monetary incentive such as a finders or referral fee.

Nice. If you’re on a FB group for the 21/22 models should let them know about that. many people hate it. But it really does save fuel. To each their own. Mine never came with one so I cannot say for sure if i would hate / love it. =\
