The OBDCAR RA003 AFM/DFM Disabler is a compact, plug-and-play device designed for V6 and V8 GM vehicles. It disables the Active or Dynamic Fuel Management system, ensuring your engine runs on full cylinders at all times without altering the factory ECU.

I have been using this Disabler for about 3500 miles now....city and highway... and it works as it should. The engine stays in V8 mode at all times. There has been no change in my gas mileage, and so far, no adverse operational issues. I have left the car sitting for three and four days with the device plugged in, with no indication of significant battery drain.

I bought this dabler for my 2014 gmc sierra with a 5.3l v8. So far it works great! the truck is now shifting smoother because its not having to shift due to afm kivking on or off, and certainly saves wear and dear on the torque converter this way. my gas milage has decreased slightly on the highway as expected, but not ebough to really be an issue(i.e 11.5 liters per 100 kms instead of 10.9 l per 100 km difference), but i've noticed something else. my gas milage in-town has vastly improved. The one thing i will warn you as i found out the hard way a couple nights ago in our -40 cold snap in Alberta, you must unplug this module when it gets down below -30 celcius, or it may wreck the module and kill your battery in the process. luckily after mine warmed up for 24 hours, it is working again.
