An Active Fuel Management (AFM) disabler is a device designed to deactivate a vehicle’s AFM system. AFM, also called cylinder deactivation, is a technology used in some modern vehicles to improve fuel efficiency by shutting down half of the engine’s cylinders during light load conditions. While this technology can improve fuel economy, it has been associated with issues such as increased oil consumption, accelerated engine wear, and rough idling.
AFM disablers function by intercepting signals from the vehicle’s computer that control the AFM system, preventing it from engaging. This allows the engine to operate on all cylinders continuously, which can potentially improve performance and reduce the likelihood of AFM-related issues. Many vehicle owners choose to install AFM disablers as an aftermarket modification to address potential problems associated with the AFM system.
By deactivating AFM, owners may improve their vehicle’s performance and longevity. Some drivers also prefer the consistent feel of a vehicle operating on all cylinders rather than one that switches between cylinder activation modes. AFM disablers can be a useful tool for those seeking to optimize their vehicle’s performance and reliability.
However, it is important to note that using such devices may affect fuel efficiency and could potentially impact warranty coverage.
