AFM/DFM Disabler — Active Fuel Management Disable Device for V6 & V8 GM Motors

This plug-and-play AFM/DFM Disabler is made for General Motors vehicles equipped with Active Fuel Management or Dynamic Fuel Management, including cars, trucks, and SUVs with V6 and V8 engines. It forces the engine to operate with all cylinders active at all times, preventing the AFM/DFM system from deactivating cylinders. Installation is quick and simple — plug the module into the vehicle’s OBD-II port and it begins working immediately. The unit does not reprogram or permanently alter the factory ECU; unplugging it returns the vehicle to its original factory settings. Please verify vehicle compatibility before purchasing.
