ROPODE AFM/DFM Disabler with On/Off Switch for Compatible GM V6/V8 Trucks

Take control of AFM/DFM operation in your compatible GM vehicle with the ROPODE Switchable AFM/DFM Disabler.

This plug-in device is designed to reduce unwanted V4/V8 mode switching, hesitation, shudder and inconsistent throttle response. The built-in switch lets you choose the device's operating state when needed, giving you more control for daily driving, towing and maintenance checks.

Installation is simple: connect the device to the vehicle's OBD-II port and follow the included instructions. No ECU reprogramming, engine modification or special tools are required.

When the disabler is active, the engine is designed to remain in full-cylinder operation. When the device is switched off or unplugged, the vehicle can return to its factory operating logic, subject to vehicle compatibility and product configuration.

Designed for selected GM vehicles equipped with AFM or DFM. Always confirm your vehicle year, make, model, engine and application before ordering.
