Carbyte DFM Disabler 2025 Vehicle Beta Testing

sanny651 · May 13, 2025

I've had my Carbyte now for about 3 months or so and I really like it. I haven't noticed any material mileage differences at all. I also have thoroughly enjoyed the auto stop delete. Most of my driving is local as I live in town and run here or there. So that's definitely been a plus. I just got a new engine in early Feb of this year, so I wanted to make sure I did as much as I could to avoid a recurrence, be it from incorrectly manufactured parts or DFM related terrorism. This helps me on that front. Nice work Carbyte! I was so impressed with it that I bought my future son in law one as well.

No, I'm not a spokesperson and my daddy doesn't own the company. HAHA! I just wanted to give some support to a company who is making a quality product and keeping it affordable for average rubes like myself.

I’ve lost a few mpgs but it’s also related to the borla exhaust and slightly bigger tires. I appreciate not having to hit the start/stop button anymore and this is a must if you have an exhaust. I never knew dfm was so busy before. Especially the coasting shutoff.

Here's a brief update on the Carbyte: Three months have passed since the last post, and it's still running smoothly with no issues. Everything is functioning as expected. I'm very happy with the Carbyte DFM disabler.

I was looking to purchase one of these today on Amazon. but I saw this reviewers post. If their statement is true, I won't be purchasing one because I love having my truck in Sport mode all the time, cold starts are awesome

. Can someone verify this statement? Quote from Amazon reviewer ". It looks to reset your driving mode back to 'Normal' every time you stop/start the vehicle (ie. you select 'Sport' mode, drive around, turn vehicle off, start vehicle, drive mode will be in 'Normal' mode). "

Is that not the default OEM behavior? My '23 and '25 both start out in Normal mode unless I shut off the engine in tow/haul.

Sorry, Denali Ultimate owners gets persistent Driver mode. But am wondering if this devices forces a reset to Normal. Guess I should not ask in a AT4 forum, but this appears to be the only good location for info about this device.

Just wanted to follow up, someone in another forum answered me and said it does NOT affect the mode your in after turning on and off the truck in a Denali Ultimate. Thanks guys!

@gemarsh is correct - you won't need new hardware. The new vehicle compatibility will be added via firmware updates.

Unfortunately the current disabler firmware will not function on a 2025 Yukon Denali, even partially. However, you can still use Carbyte as a scan tool using the OBDLink app (iOS/android).

So, is this still the case? No Yukon Denali 2025 functionality yet?

I haven't tested in awhile or checked if there is a firmware update yet.

If it matters, since my last post in January in this thread, GM pushed some kind of software update for the 2025 Yukon Denali.
If you had the Carbyte installed, the update would keep failing.
I didn't figure out why the update failed until my 3rd attempt and I unplugged it

Hello all . New member , new owner of a Yukon at4 ultimate, looking to disable the time bomb feature

as of this AM Carbyte website says it works on 2025… Sierra 5.3/6.2l but not specifically Tahoe/Yukon

So my GM update kept failing, if I remove the CARBYTE and get the GM update will the Carbyte still keep all its functions or will it be a scanner only like the Tahoes?

Any other "25 owners get the GM update and still have the DFM and auto start stop turned off?

In my 25' Yukon, it kept failing to update also. Once removed, the update work.
As posted earlier, 25 doesnt work correctly
