It was easy to set up. I installed it on a 2022 silverado ltz with a10 speed transmission 5.3 liter motor. It runs smoother than it ever has. The transmission is smoother too. I guess the truck is not fighting itself to figure out what gear it needs for how many cylinders it is using. I had to learn how to drive it again, it has so much power. The stop and go is locked out. You have ability to turn both features on and off in the app. the stop/go and and the fuel management. I emailed customer service with some questions, about the lights and battery drain. They where very prompt and curious, with their help. They assured me it shuts off after a short time of not running. It is Quality product, not a quirky piece of junk. The bad news: Gas milage dropped by 3 mpg around town and 2mpg on the interstate. My mileage gage, looks like a scoreboard counting down at a ball game, it counts down so quick at a drive through. Just a wild guess, but you could burn a 1/4 of a gallon of gas waiting on a Big Mac. Or so it seems. I pulled my 9000 pound camper and got about the same as always 9 mpg. I love the way the truck runs, but I am not sure I can afford it. My neighbor is a mechanic and he said, I can pay a little at a time now or plan on paying a lot for motor repairs/replacement in the near future. He paid a lot more than I did, to get his older chevy reprogrammed to lock out fuel management. I am keeping it. I need the truck to last. Review: Easy plug and play - This is working as designed in my 2025 Sierra 1500 with the 6.2. I can have it set to completely disable both cylinder deactivation and auto start/stop or choose which I want. Also will read engine codes if I ever need it too. ## Features - Vehicle Compatibility: Carbyte works with a wide variety of GM vehicles, including the 2022-2024 SUVs and 2022-2025 trucks, as well as 10-speed transmission vehicles β€” see supported vehicles list below. - AFM/DFM Disabler: In Full-Time V8 Mode, Carbyte disables the AFM/DFM system and keeps the engine firing on all cylinders, all the time. - Start/Stop Disabler: Eliminate the annoying Start/Stop feature, keeping your engine running 100% of the time. - Plug-and-Play: Stand-alone functionality allows Carbyte to work by simply plugging in the device.

I can have it set to completely disable both cylinder deactivation and auto start/stop or choose which I want. Also will read engine codes if I ever need it too. ### ⭐⭐⭐⭐⭐ YES IT WORKS ON C8 CORVETTES *by A***. on December 8, 2025* Works as advertised. My husband and I have a 2020 and a 2022 C8 Corvette. It works perfectly on both. The key is to do it in the correct order as it says in the instructions. 1) download the app 2) plug in the Carbyte 3) start the vehicle 4 search for any firmware updates and install using the app on your phone 4) ready to drive. The Carbyte will only start working once the car has reached at least 167 degrees. Its a great product and the only one we have found to actually bypass the AFM on a C8. Range and other devices on here do not work. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/663962262-afm-dfm-disabler-and-auto-start-stop-eliminator-for-2005](https://www.desertcart.us/products/663962262-afm-dfm-disabler-and-auto-start-stop-eliminator-for-2005) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-18*
