Benowo AFM Disabler OBD2 for GM V6/V8 — Plug-and-Play AFM/DFM Delete, No-Wire Install, Reversible

Benowo AFM Disabler is a plug-and-play OBD2 module that prevents Active/Displacement Fuel Management engagement on compatible GM V6 and V8 vehicles without altering factory wiring.

If your GM truck or SUV uses AFM/DFM and you want a reliable way to stop the engine from switching between cylinder modes, this OBD2 device intercepts the diagnostic communications and keeps the motor running in full-displacement mode. It installs in seconds through the OBD-II port, requires no mechanical changes, and can be removed to return the vehicle to its factory state. Designed for everyday use, the module is low-power and compatible with many Chevrolet, GMC, Cadillac, and other GM models.

How does the Benowo AFM Disabler work with my vehicle?

The unit communicates with the vehicle’s diagnostic network to inhibit AFM/DFM activation commands from the engine control systems. It does so without cutting wires or altering factory modules, preserving vehicle integrity and warranty-sensitive components. Because it integrates through the OBD-II port, the installation is reversible and nondestructive.

• Intercepts AFM/DFM diagnostic signals via the OBD-II interface
• No splicing or permanent modifications to factory wiring
• Can be removed to restore original vehicle behavior

Will installation affect my daily driving or battery life?

The device is engineered for continuous connection and uses very low power so it won’t noticeably drain the battery during normal operation. Once plugged in, it runs passively and maintains stable vehicle behavior under typical driving conditions. There are no changes to throttle response or drivability caused by the module itself.

• Designed for minimal power draw during everyday use
• No impact on throttle mapping or engine performance from the module
• Stable operation for commuting, towing, and highway driving

Which GM models and engines are compatible with this AFM disable module?

This OBD2 disabler is tailored for many GM V6 and V8 platforms that use Active Fuel Management or Displacement Fuel Management. Common fitment includes Silverado, Sierra, Suburban, Tahoe, Yukon, Camaro, Colorado, Escalade and similar chassis, but check vehicle year and engine variant for exact compatibility. If your vehicle uses factory AFM/DFM and accepts OBD-II diagnostic modules, the Benowo unit is likely supported.

• Compatible with a wide range of GM trucks and SUVs (V6 & V8 AFM/DFM systems)
• Commonly used on Chevrolet, GMC, and Cadillac models
• Verify fitment for specific year/engine combinations before purchase

Can I remove the module later, and will it leave any trace?

The AFM disabler is fully reversible: simply unplug it from the OBD-II port to return the vehicle to factory operation. Because it works through the vehicle’s diagnostics rather than altering wiring, there are no physical changes left behind when removed. This makes it a practical temporary solution for owners who need flexibility.

• Plug-and-play removal restores original vehicle settings
• No permanent wiring splices or hardware modifications
• Ideal for leased vehicles or situations requiring original configuration

Who is this for: The Benowo AFM Disabler is aimed at GM owners who want to prevent cylinder deactivation for consistent power delivery, improved towing feel, or to avoid known AFM-related noise and wear concerns without committing to permanent vehicle modifications. It’s suited for daily drivers, fleet vehicles, and enthusiasts who prefer a reversible, easy-to-install solution compatible with many Chevrolet, GMC, and Cadillac V6/V8 models.
