It connects via the OBD-II port and communicates with the vehicle to keep the engine in full-cylinder mode while remaining fully reversible when you remove it. The unit uses a four-LED indicator to show active or standby status and is built for durability with dedicated customer support from Cytrobe Auto Parts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this device change engine behavior while driving?\u003c\/h3\u003e\n\u003cp\u003eWhen installed, the AFM Disabler signals the vehicle to ignore AFM\/DFM commands and keeps all cylinders firing during motion.
