It’s designed for quick installation with no technical setup, and it communicates with the vehicle without altering the original ECU programming. Before ordering, confirm your model year and transmission compatibility — it’s not compatible with 2022 refresh models or 10-speed automatic transmissions.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the OBDAFM device work and is it safe for my engine?\u003c\/h3\u003e\n\u003cp\u003eThe module intercepts AFM\/DFM control signals through the OBD-II interface and prevents the system from entering cylinder deactivation modes while leaving the factory ECU untouched.
