Maintain full-cylinder operation with the RA003 AFM/DFM Disabler. Designed for compatible GM V6 and V8 vehicles, this module disables Active Fuel Management (AFM) or Dynamic Fuel Management (DFM), preventing the system from deactivating cylinders while driving.
The compact module connects directly to the vehicle’s OBD-II port for convenient installation. By maintaining full-cylinder operation, it helps provide a more consistent engine feel and exhaust tone—ideal for drivers who prefer all cylinders to remain active.
