Range GM AFM Disabler Blue

The Range GM AFM Disabler Blue is a computer module designed to disable Active Fuel Management (AFM) on General Motors vehicles equipped with this cylinder deactivation system. This product is ideal for GM truck and SUV owners who experience reliability issues related to AFM technology, such as valve train wear and rough idle complaints.

This compact module functions as a plug-and-play signal interceptor that integrates into the factory wiring harness with minimal modification. It intercepts the AFM solenoid signal, allowing for consistent cylinder firing across all eight cylinders without the need for expensive ECU tuning or dealer intervention. Installation typically takes under an hour and does not require computer reprogramming or custom tuning.

The Range GM AFM Disabler Blue is compatible with 5.3L, 6.0L, and 6.2L LS-based engines found in GM trucks and SUVs, including models like the Tahoe, Suburban, and Denali from 2007 onward. This product is particularly beneficial for truck and SUV enthusiasts, fleet operators, and mechanics looking to enhance vehicle performance and reliability.
