OBDCARAFM/DFM Disabler Active Fuel Management Disabler AFM Delete Compatible with V6 & V8 GM Motors

I'm using this disabler in a 2011 Chevy Silverado and it works without a hiccup. My truck was using some oil and after using this it has stopped it from doing so. The cylinders all run and don't cut out and this has lead to better performance and less oil consumption. Happy with the results and would recommend. Thumbs up!

I previously ordered a similar item from another manufacturer for my 2014 Corvette Stingray Z51. I thought I'd try another to see if there was any difference between the two, even though in theory they should do the same thing. I was mistaken. This unit performs differently than the other, in that the acceleration alone is noticeably smoother, and so is the idle. I also didn't feel any transmission jolt when cruising around town and gently hitting gas. The other unit for sure had that. I am super surprised at how much different this unit works, but quite frankly, I'm glad I opted to try this one. Great buy for those in the market!

Improved my SUVs milage. The motor runs smoother going up hills now. Speed is easier, the motor doesn't rev up as much so it isn't so hard on the motor.

Tried it tonight on a 2018 Suburban with 6-Speed Auto trans and 5.3L V8 with AFM and it works beautifully. Shut off AFM totally and kept vehicle in V8 mode constantly no matter how I tried to trick it into going into V4, in city and highway driving conditions - same perfect function.No error codes were thrown that I could detect on my second (splitter) OBD2 port, nor did the car detect any in the info display, nor in the app, which would have screamed at me with push notifications if anything as amiss. No disablement of ABS, nor of Stability Control, nor of anything else that these AFM disablers sometimes shut off to achieve constant V8. This one apparently has it figured out.Very smooth, and nice that I don't need to use L5 all the time to keep it in V8 - I can just drive in D and not worry about it. Super little device that I highly recommend.

This OBDCAR AFM/DFM Disabler Active Fuel Management Disabler specific to a number of makes and models was tested and works as it's supposed to. If your vehicle is compatible, it's a simple plug and play using your car, truck or suv's obd port. It works by keeping all cylinders running and shuts off the AFM/DFM system. No codes are thrown and my truck runs smoother with more power. Something to keep an eye on is water temp and transmission overheating that may come along from using these type of devices. For regular driving I'm having no problems with it and I do remove it when I shut off the engine.
