• Some applications may still encounter 0-Cylinder Mode while coasting when 0% throttle input is detected at the ECM
• We do not control the in-cab Auto Start/Stop switch on the dash, so it will still iluminate on/off with the button being pressed as it factory, even though the system is always disabled with our module installed at the ECM.
• We do recommend removing the DFM Module before performing any GM Over-the-Air updates or visiting the dealer for vehicle updates via OBD-II port
• Made in USA

*Some vehicles may still engage 0-cylinder mode while coasting with this product installed. During extensive testing, it was found that completely disabling this function led to undesirable driving conditions and safety concerns. Disabling 0-cylinder mode while coasting resulted in a notable decrease in fuel efficiency, with a loss of 2-3 MPG, as the engine continues to fuel and fire the injectors even during coasting. This fueling also creates an unsettling sensation during deceleration, as it feels like the vehicle is still accelerating slightly, despite 0% throttle input. This requires harder braking, especially in scenarios like towing or descending a long grade, leading to undesirable driving conditions.
