The Range AFM/DFM Disabler allows your V6 or V8 GM vehicle to run in full cylinder mode at all times, preventing the Active or Dynamic Fuel Management system from dropping cylinders.
Range's patented technology is the only product that will disable Active and Dynamic Fuel Management without reprogramming the factory ECU. Full power delivery all the time without factory warranty concerns. It is suggested the device be unplugged if the vehicle is not being driven daily or left for a few days. There may be a power draw on the battery in some applications.

Simply plug into your onboard OBD-II port and it instantly begins working to eliminate the AFM system.
Also disables Auto Start/Stop.
The Range AFM/DFM Disabler does not reprogram your factory ECU.
Leaves no trace. Unplug it to return to factory settings.
Fits all V6 and V8 General Motors (GM) active or dynamic fuel management vehicles, includes cars, trucks, and SUVs.
