Carbyte 2024 Tahoe 6.2l

[BacDoc]

Carbyte is a plug and play that eliminates auto stop and keeps your engine running V8 all the time and deactivates the DFM. All for $149!
Sounds too good to be true and you know what they say about that!

Anyway, I purchased a Carbyte off Amazon for $149 and it truly is plug and play. Plugs right into the OBD port with no problem and I downloaded the free app on my phone. Everything went smoothly and just as advertised - the auto stop is eliminated even though the light on the dash switch is still on. With out the Carbyte I would have to push the switch and the light would go off. Then the auto stop was deactivated. With the Carbyte plugged in you never have to push the button. Also the DFM is disabled and the engine runs on all 8 cylinders all the time. I have only had this for a week but so far the auto stop is gone and I think engine is full time V8 at least that’s what the display and phone app tells me. No engine issues or warning lights or any codes have come up.

According to the phone app the full time V8 is activated and auto stop eliminated. At first I thought you needed to connect to the phone app but even if the phone app is disconnected the Carbyte module still works and the display on the unit will indicate if it is connected. I am pretty sure the DFM is disabled as most of my driving is on smooth highways that have 45-50 mph speed limits and my mog on these roads is noticeably less from the limited time I have been driving with this. I will follow up with some comparison numbers. Engine seems maybe smoother but I never could really feel the DFM kick in even with audio off and paying attention I really couldn’t feel anything different.
Some say you need to hit 40 mph before the Carbyte is enabled but I haven’t had the auto stop go on even at lower speeds.

Now for the dilemma! When the Carbyte module is plugged in my power assist steps don’t work when door opens or closes. The steps are aftermarket AMP Research and they are amazing! I love them and they are nicer and faster than the OEM power assist steps.

When removing Carbyte and plugging the module back in everything works fine. If the Carbyte is plugged in the steps work perfectly with the manual switch on dash but don’t respond automatically to door open or close.

So now I can enjoy not pushing the button for auto stop but I have to push button to activate the power steps. Uggh!
Before Carbyte I had to push button to eliminate auto stop but my power steps worked automatically! Uggh!
Almost back to square one!

I contacted Carbyte and they got back to me with in a day and are attempting to troubleshoot this for me. I have to say they are pretty responsive but not sure if they can remedy this and get the steps to work automatically unless they have an adapter that integrates with the OBD and the Carbyte.

I will update as this develops…..
So far for the ease of install, eliminating auto stop and running full time V8 it does all that for $149 and besides the power step issue it definitely does what it claims on my 2024 6.2l.

This is the module plugged in to the OBD port

 

[Blueinterceptor]

Do you think it will work with the factory retractable steps?

 

[BacDoc]

I think it depends on the plug in the OBD port. I bought truck new and don’t recall if the OBD port was plugged or just a cover/cap. The Amp Research connection is wired into the OBD plug in my truck.

My guess is that it should if nothing else is plugged into the OBD.

This is more a question for the Amp Research folks, not likely a Carbyte issue. The Amp Research much monitoring the OBDII port for some sort of wake up if you go to open the door?

Do the steps deploy properly if you open the door after driving?

The other option is the Range DFM disabler that goes inline with the ECU, pretty simple and easy install. I have had a Range device on my 2024 for about 9 months so far without problems.

 

[BacDoc]

The power steps work normally without the Carbyte plugged into the OBD port.
Even with Carbyte plugged in the steps work manually with the switch on the dash.

Since I bought this Tahoe new but the dealer had the Amp Research installed, I don’t know what is plugged into the OBD port with factory power steps. Maybe someone with factory power steps can post their situation?

So far I’ve been putting more miles on and no problems with anything else and the Carbyte is working perfectly even at speeds below 40 mph the auto stop is eliminated.

Did you look under dash with flash light? Perhaps there’s an OBD splitter and another device like low jack messing with the truck.

I had similar problem with carbyte, it worked great but as soon as i plugged in my scan guage carbyte quit working. I preferred the guage to the dfm delete so sent it back. Our obd2 connection is temperamental at its best.

Often you cannot have 2 different devices connected to the OBDII port and sending and receiving data at the same time. As for the CarByte and the Scan Gauge, suggest you consider the Range DFM delete, it plugs into the connector behind the front drivers wheel directly to the ECM. Does not impact the OBDII port in any way from what I have seen. I can connect devices to the OBDII port and log data while the Range device is connected.

As for the original posters concern about the running boards, he should contact the running board vendor, not the Carbyte vendor. The Carbyte vendor probably knows nothing about running board operation unless they have spent time previously working with other customers that have the running boards and ran into a problem.

thanks for the idea

I have had the Carbyte in my 24 5.3 Tahoe since October. Works great. One thing, using your phone app, you can toggle all off, auto stop, cylinder deact, or both.

 

[Scarey]

The device works as claimed. The app is a little glitchy and unresponsive. If you want to turn on or off simply plug or unplug the device and don’t bother with the app.

As some have said my issue with the power steps is not so much the Carbyte but the aftermarket Amp Research steps. It is a shame as both work well but they don’t play well together. AMP Research steps are awesome and very fast to deploy and they might be slightly wider with better construction than the OEM power assist steps.

The steps work perfectly with the manual switch on the dash but they don’t respond automatically when the doors open/close with Carbyte plugged in. So I am back to pushing a button!

It is the door position sensor that needs the original OBD plug to work and the guys at Carbyte are working on finding a solution, maybe there’s some interface adapter that can recognize the door position to activate the steps with the Carbyte in place.

They told me they would refund me but for the cheap price of $150 I will keep it even if they can’t resolve the door sensor issue. I love the auto stop disabled and full V8 mode during any speed.

The auto stop still works even in short trips and low speed driving - it seems to work even when driving below 40 mph. I have heard some say it doesn’t activate until 40 mph is reached but that hasn’t been my experience.

For the price Carbyte is a great option.

So I have been running the Carbyte for about 3 weeks and it works as advertised. Nothing seems to be adversely affected, no glitches and fuel economy is pretty much identical. For me the best stretch of road is a 12 mile section of A1A here in Florida. It’s probably the best road for maximum fuel efficiency as it’s smooth flat, very steady traffic with steady 50-55 mph speed and the speed limit is 50 mph. I get between 22-24 mpg on this stretch of road before and after installing Carbyte. So if it’s running full 8 cylinders then DFM is not noticeable fuel savings on this 12 mile stretch at 50 mph.

The auto stop is permanently disabled and it’s supposed to be full time V8 but I have no idea how to verify this. I’ve turned off the audio system and listened carefully and tried to be as open as I can to the vehicle input but haven’t noticed any difference there.

The app is adequate I guess but I haven’t used it for anything yet. My main concern was getting rid of auto stop and running V8 full time and this device is very easy and cheap option for that. Their customer service is available by email and they do get back to you within a day.

Overall a great product that is easy to install and remove and the retail of $150 is fair price.

Update -

I use one of the fuel usage options on the center display and this gives you a current mpg, best and average. Before installing Carbyte the current mpg would go to 99 when taking foot off the pedal and always coasting downhill with no throttle. After installing Carbyte it would only hit 45-55 mpg coasting. I didn’t notice any significant changes in fuel consumption with ASS and DFM disabled, but that display never went to 99 coasting after installation of Carbyte. Think this is proof of running full time V8.

Yesterday I was driving over the bridge that is part of my normal drive and when I looked down at instrumentation I saw 99 going down the bridge and off throttle. When I got a chance to pull over and check, the Carbyte was gone. I didn’t pull it out, nobody has been in the vehicle but me and Tahoe spends the night in my garage. Nothing else is missing and no evidence of vehicle being broken into. I haven’t had it in for service since I got Carbyte.

Really weird, I guess I must have hit it with my foot getting out but I think I would have felt that. No signs of it on my garage floor, or around my driveway. The device plugged in nice and snug and it definitely isn’t any fault of fitting. If I can’t find it I will probably get a new one as it worked well and disabled the annoying ASS.

I second getting the Range module. It’s not taking up the ODBII port BUT I also remove it anytime it goes in for service which is a 10 minute process each time.

 

[BacDoc]

Update!

I “found” the Carbyte! It was in the side door pocket. We went offshore fishing that day and usually I drive the tow vehicle/trailer and my buddy drives the boat onto the trailer. This time there was a problem and I had to drive the boat and my buddy got back in the Tahoe to pull the trailer out. He never drove a newer model truck and reached down to release the parking brake. Of course there is no mechanical parking brake but he felt around and pulled the Carbyte out of the OBD port and forgot to tell me. Of course the truck ran no problem.

I finally found it in the door pocket and replaced it and back to normal!

Where does the Range connect?

Just a question, do you have the Range DFM delete unit on your 2024? I have a 23 tahoe w/5.3l v8 and want to get rid of the DFM but still have lots of powertrain warranty left that i cant do the mechanical delete, but would love to have the engine stay in full v8 all the time.

Yes I put the range module on my 2024 at about 275 miles. I've got 8,500 mi on the truck now and everything's been fine. I believe the range module may still pump the lifters down under deceleration. But you can also put the vehicle in L9 around town up to 55 mph and it will also disable the DFM.
