Mastering Engine Performance with Active Fuel Management Disablers
Active Fuel Management disablers are devices that are designed to disable the cylinder deactivation feature in many modern vehicles. Doing this provides drivers with full control over their engine's performance.
Understanding Active Fuel Management
Active Fuel Management, also known as cylinder deactivation, is a technology used by various automakers to improve fuel efficiency in vehicles. By automatically turning off some of the engine's cylinders under certain driving conditions, such as when cruising at a steady speed on the highway, AFM can reduce fuel consumption, often by a significant amount. But this feature is not always needed or even desirable. For instance, drivers who prioritize power and performance over fuel economy are better off without it.
What Are Active Fuel Management Disablers?
AFM disablers are small plug-and-play devices that prevent a vehicle's engine from shutting off cylinders and allows them to maintain full power at all times. They are popular among performance enthusiasts and those who drive in conditions where full engine power is necessary or beneficial, such as in towing or in hilly terrains.
Types of Active Fuel Management Disablers
AFM disablers come in several varieties. The following are the two (2) most common devices on the market:
-
Plug-and-Play Modules: Plug-and-play modules are the most common type of AFM disablers. They connect directly to the vehicle’s OBD-II port and instantly disable the AFM system. Because they're easy to use and require no permanent modifications to the vehicle, they are a popular choice. The AFM can be quickly re-enabled at any time by unplugging the module from the OBD-II port.
-
Programmable Tuners: Some power programmers have the capability to disable AFM systems. They can be turned on or off according to the driver’s preference, providing more flexibility than standard programmers.
Benefits of Using Active Fuel Management Disablers
-
Enhanced Engine Performance: Drivers can enjoy more consistent power and a smoother driving experience by keeping all cylinders active. This is critical for drivers who prioritize performance over fuel economy.
-
Reduced Engine Wear: Some studies suggest that constant switching between active and inactive cylinders can lead to uneven wear, which may cause the engine to develop problems sooner than it otherwise would. Based on this data, disabling AFM may extend the lifespan of the engine.
-
Customization and Control: AFM disablers give drivers full control over their vehicle’s engine configuration. This lets them personalize and customize their driving experience based on preferences and road conditions.
Choosing the Right Active Fuel Management Disabler
When selecting an AFM disabler, you should first consider the type of vehicle you have, as well as your specific needs. For instance, what do you mostly use the vehicle for? If you're looking for a simple and reversible solution, plug-and-play modules are the clear winner. On the other hand, if you want more control over your vehicle’s performance, you might prefer a programmable tuner, as it offers more options and customization. Regardless of the model you choose, make sure it is compatible with your vehicle's make and model to avoid any complications that could damage either the vehicle or the device.
