Introduction
The Range Technology RA003R plug is a highly popular device among truck and SUV owners, especially those with GM vehicles. This plug-and-play solution is designed to disable Active Fuel Management (AFM), also known as Displacement on Demand (DoD), helping drivers maintain engine performance and improve driving experience.
What Is the Range Technology RA003R Plug?
The RA003R plug by Range Technology is an innovative AFM/DoD disabler made for General Motors (GM) vehicles. It simply plugs into your vehicle’s OBD-II port, allowing you to instantly disable the AFM system without making permanent changes to your car’s ECU or engine.
How AFM/DoD Systems Work in GM Vehicles
Active Fuel Management, or Displacement on Demand, is a system that deactivates some of the engine cylinders under light loads. It was designed to improve fuel economy. While the intention is good, it often results in performance drops and engine issues.
Why Drivers Disable AFM with the RA003R Plug
Many GM owners dislike how AFM causes rough engine performance and unwanted vibrations. Over time, it can also contribute to engine wear. The RA003R plug eliminates these problems by ensuring all cylinders fire consistently, offering smoother rides.
Key Features of the RA003R Plug
The Range Technology RA003R plug offers several features that make it a top choice. It is easy to install, leaves no trace after removal, and does not void your warranty. It also allows full V8 mode without interfering with other vehicle functions.
Easy Plug-and-Play Installation
No tools or mechanical skills are required to use this plug. Simply insert it into the OBD-II port under the dashboard, and the RA003R will take over the AFM control system immediately.
Safe and Reversible
Unlike permanent tuning, the RA003R does not reprogram the ECU. This means you can remove it anytime to restore the factory settings. It leaves no footprints, ensuring your vehicle’s warranty stays intact.
Full Power When You Need It
With all cylinders active, your engine performs at its best. This is ideal for towing, off-roading, or spirited driving where full power is necessary. The RA003R helps unlock the true potential of your GM engine.
Compatibility with GM Vehicles
The RA003R plug is compatible with most GM vehicles made between 2005 and 2020 that use AFM/DoD technology. This includes trucks like the Silverado, Sierra, Tahoe, Suburban, and SUVs such as the Yukon and Escalade.
Supported Engines
This device works perfectly with V6 and V8 engines equipped with the AFM feature. Some popular engines include the 5.3L V8 and 6.0L V8 used in many GM trucks and SUVs. Be sure to check the compatibility chart before purchase.
Not for Start/Stop Engines
If your vehicle uses automatic start/stop technology, you may need a different module. The RA003R is specifically for disabling AFM and may not affect or bypass other fuel-saving features.
Benefits of Using the RA003R Plug
Disabling AFM with the RA003R plug offers several performance, maintenance, and comfort benefits. Many drivers report a more consistent driving feel, better throttle response, and fewer engine issues over time.
Improved Driving Experience
Once the plug is installed, you’ll notice that your vehicle feels more powerful and responsive. There’s no more switching between 4 and 8 cylinders, which makes driving smoother and more enjoyable.
Protect Your Engine
AFM can lead to lifter failure and oil consumption problems. By disabling it with the RA003R, you reduce wear and tear, potentially extending your engine’s lifespan and avoiding expensive repairs.
Better Towing and Off-Road Capability
When towing or driving off-road, full power is essential. The RA003R ensures your engine doesn’t switch to fewer cylinders during heavy load situations, giving you peace of mind and consistent performance.
How to Install the RA003R Plug
Installation is extremely simple. Locate the OBD-II port (usually under the dashboard near the steering column), insert the plug, and wait for the LED light to confirm it’s active. That’s it—no special tools or programming needed.
Step-by-Step Installation Guide
- Turn off your vehicle.
- Plug the RA003R into the OBD-II port.
- Wait for the green light to appear.
- Start the engine and enjoy full-time V8 performance.
