An AFM/DFM disabler is a plug-in device designed to help you manage your vehicle's Active Fuel Management (AFM) or Dynamic Fuel Management (DFM) system. These systems automatically switch your engine between different cylinder modes to improve fuel efficiency. By using a disabler, you can keep your engine running on all cylinders, which some drivers prefer for a consistent driving feel. It's important to note that results can vary depending on your vehicle and driving habits. Always check your vehicle's compatibility before purchasing.

Installing a fuel economy module is usually a straightforward process.

1. First, make sure your vehicle is turned off and parked safely.
2. Locate the OBD-II port, typically found under the dashboard near the driver's seat.
3. Plug the module into the port until it's securely connected.
4. Once installed, start your vehicle to allow the module to communicate with your car's system.

Using an AFM/DFM disabler may have implications for your vehicle's warranty. Some manufacturers may view the use of aftermarket devices as a modification, which could impact coverage.
