Enjoy consistent full-cylinder operation with the OBD AFM/DFM Disabler. Designed for compatible GM vehicles equipped with Active Fuel Management (AFM) or Dynamic Fuel Management (DFM), this module connects to the vehicle’s OBD-II port to disable cylinder deactivation.
By keeping all cylinders active, it helps reduce the changes in engine feel and exhaust sound associated with switching between cylinder modes. Its compact plug-in design makes it a convenient option for drivers who prefer continuous full-cylinder operation during everyday driving or towing.
Key Features
- Designed to disable AFM/DFM cylinder deactivation on supported vehicles.
- Connects directly to the vehicle’s OBD-II port.
- Helps maintain consistent engine operation and exhaust tone.
- Compact design for convenient installation.
Compatibility: Please confirm your vehicle’s model, year, engine, and AFM/DFM system before purchase.
