Active Fuel Management Disabler Device Disable Delete AFM DFM Function Compatible with GM V6 V8 Vehicle Car Truck

Great product it worked flawlessly and it seems well made and easy to use

Works just like the high priced ones but much cheaper!

This product has worked flawlessly with no issues for a year now. Made my trucks ride a lot smoother with out that pesky V4 mode kicking in every 10 seconds not to mention it will help with lifter failure. The only issue I discovered was it will not pass an OBD2 inspection. You will need to unplug it for at least a week before your inspection. Otherwise this is definitely a must for your truck.

Had my doubts that it would actually do anything but the truck ran well and it seemed to be always in V8 mode. This was good because the V4 power and switch back would bog my motor when getting on the highway.

Rip-off item. Does nothing for your vehicle. Won't work. Your vehicle is calibrated for specific settings and this chip will do nothing for your car or truck.

Completely hassle free from the order to install. Works as described and in addition this part appears to be the same shipped as advertised for purchase. Just plug in the dlc port, lights flash when initializing. All LED lights stay lit (2017 Chevy Camaro ss 6.2l) when it's ready. Works and performs as advertised, AFM is disabled, confirmed by instant fuel mileage screen mode v8 all the time. As for longevity I can not comment yet. Half the price of other models. I hope this review helps. God bless

Easy, just plug it in, and it works. When it is plugged in, my corvette never drops down to V4 mode. I notice no difference in average MPG and I believe it is better for the engine's long term health not do always go back and forth between V8 and V4.

I have a 2017 Corvette with AFM. Researching this "feature," I became concerned that cylinder deactivation might increase wear-and-tear over time. I looked at competing products and asked around for advice. I decided to try the Yesemei AFM Disabler. I've only put on about 40 miles of city driving, but the "V4" indicator has not appeared even once that I noticed. Otherwise the car has driven just like it always has. If anything changes, I will certainly update this review. So far, the disabler is the solution I need at a price-point that makes it a compelling value over its competitors.
