Range Technology RA003B Active & Dynamic Fuel Management Disabler
$220.00
Keep your vehicle in full V8 mode all the time.
This is a brand new, never opened, factory-sealed Range Technology RA003B AFM/DFM Disabler in Blue. If you want to eliminate the annoying lag, shudder, and potential long-term engine wear caused by Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems, this plug-and-play device is the ultimate solution.
By keeping your engine in V8 mode 100% of the time, you get instant power delivery, smoother throttle response, and a more consistent driving experience without altering your factory ECU or voiding your warranty.
Key Features
- Full Power All The Time: Disables AFM/DFM systems to maintain full cylinder mode without dropping to 4 cylinders.
- Plug & Play Installation: Simply plug it into your vehicle's onboard OBD-II port under the dashboard. No tools, programming, or mechanical skills required.
- Safe & Reversible: Does not reprogram your factory ECU. To return your vehicle to factory settings, simply unplug the device.
- No Warranty Issues: Leaves no footprint or trace behind on your vehicle’s computer once removed.
- Eliminate Exhaust Drone: Crucial if you have an aftermarket exhaust system, as it stops the awkward sound transitions between 4-cylinder and 8-cylinder modes.
Product Condition
- Condition: Brand New in Box (NIB)
- Status: Factory sealed, original packaging, never used or installed.
- LED Color: Blue
