Description
Product Overview
The Benowo AFM/DFM Disabler is engineered to keep modern GM V6 and V8 powertrains operating in full‑cylinder mode at all times. Housed in a matte‑finished, compact shell (2.36 x 1.77 x 0.96 inches, 0.871 oz), the unit plugs directly into the vehicle’s OBD‑II port. It does not reprogram the factory ECU; instead, it intercepts the AFM/DFM signals, preventing the system from deactivating cylinders. This results in consistent power delivery, reduced valve‑lifter wear, and a smoother driving experience. The module is compatible with a wide range of 2020‑2024 GM models, including Silverado, Sierra, Camaro, Blazer, Suburban, and Tahoe, covering model years from 2007 to 2022.
Usage
Designed for both daily commuters and performance enthusiasts, the disabler works in any driving condition—city traffic, highway cruising, or off‑road adventures. Simply plug the device into the OBD‑II port, and the system activates instantly, requiring no additional tools or technical knowledge. When you need to revert to factory settings—such as for emissions testing or warranty work—just unplug the module. Its reversible design ensures you retain full factory warranty coverage while enjoying the benefits of constant full‑cylinder operation.

FAQ
Will installing the disabler affect my vehicle warranty?
No. The Benowo AFM/DFM Disabler does not modify the ECU software. It can be removed at any time, restoring the original factory configuration, so it does not void the warranty.
Is the device compatible with my 2022 Chevrolet Silverado?
Yes. The disabler supports 2020‑2024 Silverado 1500 models as well as earlier years back to 2007, covering the full range of AFM/DFM equipped trucks.
Do I need any special tools to install it?
No special tools are required. Simply plug the module into the OBD‑II port and the system activates automatically.
Can I use the disabler on a vehicle with a DFM system?
Absolutely. The unit disables both Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems, providing full‑cylinder performance for any supported GM engine.
What if I need to pass an emissions test?
Unplug the module before the test. Since the device does not alter the ECU, removing it returns the vehicle to its original emissions configuration.
