Hey gearheads! Are you looking to ditch that annoying Active Fuel Management (AFM) system in your ride? You're not alone! Many drivers find that AFM, while intended to save fuel, can cause issues like the dreaded 'AFM tick' or just a general lack of performance. So, the big question is: who makes the best AFM disabler? Let's dive into the world of AFM disablers, explore top brands, and figure out what makes a disabler truly kickass.

Understanding AFM and Why Disable It

Before we jump into brands, let's quickly recap what AFM is all about. Active Fuel Management, also known as Cylinder Deactivation, is a technology used by manufacturers like GM to improve fuel economy. The system shuts down some of the engine's cylinders under light load conditions. While this sounds great on paper, it can lead to some undesirable side effects. Common complaints include:

• The 'AFM Tick': A noticeable ticking noise coming from the engine, often attributed to the lifters in the deactivated cylinders. This is perhaps the most common reason people look to disable AFM.
• Reduced Throttle Response: The transition between V8 and V4 mode (or whatever cylinder configuration) can feel clunky and create a noticeable lag in throttle response. Nobody wants that!
• Potential for Oil Consumption Issues: Some believe that AFM can contribute to increased oil consumption over time.
• Uneven Wear: The cylinders that are deactivated and reactivated may experience uneven wear compared to the consistently firing cylinders.
• Exhaust drone: Some aftermarket exhaust systems can amplify the sound of the engine switching between V8 and V4 modes, leading to an unpleasant drone.

For these reasons, many drivers, particularly those who prioritize performance and engine longevity, choose to disable AFM. An AFM disabler plugs into your car's OBD-II port and intercepts the signals that activate the AFM system, effectively keeping all cylinders firing all the time. It is important to mention that disabling AFM could affect your fuel economy negatively and potentially void parts of your warranty, so weigh your options carefully.

Top Brands in the AFM Disabler Market

Alright, let's get down to business. When it comes to AFM disablers, several brands have risen to the top. These companies are known for their reliability, ease of use, and effectiveness. Here are some of the best AFM disabler manufacturers you should consider:

• Range Technology: Range Technology is arguably the most well-known name in the AFM disabler game. Their AFM disabler is a simple plug-and-play device that requires no tuning or programming. Just plug it into your OBD-II port, and you're good to go! They are known for their reliability and wide vehicle compatibility. Range Technology devices are designed to be non-intrusive, meaning they don't alter the vehicle's factory ECU programming. Instead, they simply send a signal that prevents the AFM system from activating. This makes them a popular choice for those who want a simple and reversible solution.

• DiabloSport: DiabloSport is a major player in the automotive tuning world, and they offer AFM disabler solutions as part of their tuning devices. Unlike the Range Technology device, DiabloSport uses a full ECU tune to disable AFM, giving you more control over other aspects of your engine's performance. Their devices often include other features like performance tuning, data logging, and diagnostic code reading. If you're looking for more than just AFM disabling, DiabloSport is a great option. However, keep in mind that using a tuner will require some technical knowledge and could potentially void your vehicle's warranty if not done correctly.

• Bully Dog: Similar to DiabloSport, Bully Dog offers performance tuners that can disable AFM. Bully Dog tuners are known for their user-friendly interface and comprehensive features. They allow you to adjust various engine parameters, monitor performance data, and read diagnostic trouble codes. Bully Dog is a solid choice if you want to fine-tune your vehicle's performance and disable AFM at the same time. Like DiabloSport, using a Bully Dog tuner requires some technical expertise and carries the risk of voiding your warranty.

• Edge Products: Edge Products specializes in performance monitoring and tuning devices, and their products often include AFM disabling capabilities. Edge offers a range of products, from simple monitor displays to full-fledged performance tuners. Their devices are known for their high-quality displays and comprehensive data logging features. Edge is a good option if you want to keep an eye on your engine's performance while also disabling AFM. As with other tuning devices, using an Edge product to disable AFM carries the potential risk of voiding your warranty.

What to Look for in an AFM Disabler

Okay, so you know who makes them, but what should you actually look for when choosing an AFM disabler? Here are some key factors to consider:

• Compatibility: This is crucial. Make absolutely sure the disabler you choose is compatible with your specific year, make, and model vehicle. Most manufacturers have compatibility charts on their websites. Double-check. Triple-check. Seriously.
• Ease of Installation: Do you want a simple plug-and-play device, or are you comfortable with more involved tuning? If you're not tech-savvy, stick with a plug-and-play option like the Range Technology device. If you enjoy tinkering and want more control, a tuner from DiabloSport or Bully Dog might be a better fit.
• Features: Do you just want to disable AFM, or do you want other features like performance tuning, data logging, and diagnostic code reading? If you want more than just AFM disabling, consider a tuner.
• Price: AFM disablers range in price from around $200 to $600 or more. Consider your budget and what features you need when making your decision.
• Reliability: Read reviews and see what other users are saying about the reliability of the disabler. You want a device that's going to work consistently and not cause any problems.
• Customer Support: Check if the manufacturer offers good customer support in case you run into any issues. A responsive and helpful customer support team can be a lifesaver if you need assistance with installation or troubleshooting.

Plug-and-Play vs. Tuners: Which is Right for You?
