ENHANCED ENGINE PERFORMANCE: BELZAR AFM/DFM Disabler is engineered to deactivate the Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems in your V6 or V8 GM vehicle, guaranteeing continuous operation in full-cylinder mode. (Disables 4-cylinder mode)
PLUG-AND-PLAY INSTALLATION: Simply plug the AFM/DFM Disabler into your onboard OBD-II port, and it starts working immediately. No need for reprogramming the factory ECU, and rest assured, it won't void the manufacturer's warranty.
COMPATIBILITY ASSURANCE: Before making your purchase, check the compatibility to ensure a seamless integration. While the AFM/DFM Disabler is compatible with most GM V6 and V8 engines, it's essential to note that it does not support 2019+ Silverado and Sierra models equipped with the 5.3L/3.6L engine and 10-speed transmission, as well as 2022 Refresh truck or SUV models.
USER-FRIENDLY OPERATION: The device features intuitive indicator lights that flash sequentially upon insertion, settling into a steady one-light display to signify a connected and operational status. It's a user-friendly solution, providing real-time feedback for peace of mind. (Unplug the AFM device if it will not be used for a long time)
CUSTOMER SERVICE: The customer service team is online 24/7, ready to answer any questions you may have about the product. We promise to provide you with up to one year free return and exchange service (non-man-made damage) to ensure that you enjoy a worry-free shopping experience in the process.
