I took the wheel off, just made it more accessible, I had a floor jack, electric impact and torque wrench.

I'm not going to, I have a good relationship with the dealer and if you subscribe to OnStar it's probably already noted.

Got the DFM diabler in
It's real easy for anyone that might be on the fence or concerned about install.
It's literally just disconnect the negative battery terminal, pull back the inner fender liner carpet thing, then remove the bottom PCM connector.
Plug the DFM disabler module in , then plug the wiring harness back into the DFM disabler module. Only downside is removing the negative battery cable you lose the memory seats positions and phone pairing, so you have to re-bluetooth your phones and reset the memory set location afterwards (which is kinda inconvenient, but not the end of the world).
POST EDIT: The Range device is not actually a DFM disabler, it's a DFM schedule modifier, parts of DFM (the 0-cylinder deceleration part) are left fully functional with this device installed. If fully disabling DFM all the time is what you want, then this device is not for you.

I don’t loose memory seats or phone pairing? Is this a “feature” of the new google trucks? I just lose the fuel trim, and automatic power window up/down which the truck relearns.
Otherwise, everything else is spot on. This is a great addition.

I never lost phone pairing or seat memory when I pulled the negative lead on my ‘22 a few months back.

IDK what the difference is, but our 23 Tahoe High Country most certainly forgot the memory seat settings and forgot all our phones ( we have teenage kids with phones too, so we had a bunch of phones that could Bluetooth in before, it forgot them all).
And the cluster did ask me roll down the passenger window after I reconnected the battery ( which I did and the windows work fine). It also turned back on the “check rear seat reminder” thing that I immediately tuned back off. Only other strange thing was the tire pressure monitoring on the dash, it was all blank until I drove for a little bit then the tire pressure numbers came back.

So I ordered one of these Range units for my 2021 Yukon 5.3. I also ordered a Auto Stop Eliminator harness because I didn't realize that the Range module also disables Auto Start-Stop as well.
That being said, I contacted ASE to return my module, and they informed me that the Range unit keeps the trucks run in diagnostic mode, and when the truck is in diagnostic mode, the check engine light is suppressed. So if you ever had a problem, you wouldn't know...because the CEL doesn't come on. Any truth to this?
ASE is also saying that the Range unit has parasitic drain on the battery that is 1000x more than their unit. Which could lead to a dead battery situation if the vehicle sits for extended periods of time.
Not trying to start a beef between Range and ASE, but just wondering if there's some truth to this.

With the Range unit plugged in/installed, if you put the vehicle to the “run” position and the CEL comes on, then I would say … that the CEL would still be working. At least I’m hoping there is no truth to what they are saying.
