Overview

The Range Technology RA003R is a compact, plug‑and‑play AFM/DFM disabler designed for select GM vehicles. By interfacing with the OBD‑II port, this patented device helps prevent the Active Fuel Management system from dropping cylinders. The result can feel like steadier power delivery across daily driving, while the factory ECU remains untouched and fully reversible by unplugging.

What it does for your drive

Engineered for practical, real‑world use, the RA003R aims to keep performance action consistent. You may notice a more continuous power feel during acceleration, especially at highway speeds or when the engine is under load. It’s built to be unobtrusive and reversible, offering flexibility for drivers who value maintainable options without permanently altering software.

Highlights from the design include a simple install path, quick status confirmation with a red LED, and a non‑destructive approach that preserves the OEM software in its original state. The module is designed to come alive as soon as it’s connected, without requiring reprogramming of the vehicle’s ECU.

  • Compatible with select Buick, Cadillac, Chevrolet, GMC, Isuzu, SAAB, Pontiac, Saturn & Suzuki GM vehicles
  • Keeps you in full power 100% of the time, no more shuddering or dropping cylinders
  • Fast and easy setup; simply plug into your onboard OBD-II port and it instantly begins working to eliminate the AFM system
  • Does not reprogram your factory ECU, unplug it to return to factory settings
  • Red LED version
  • Patented technology designed to act without altering OEM software
  • Uninstall to restore original AFM behavior at any time
  • Compact, discreet module that fits out of sight in most cabins

Note: This device offers a flexible option for drivers seeking consistent throttle response and power feel without a software reflash. Results may vary by vehicle and driving conditions, and the device is designed to be reversible so you can return to factory behavior if desired.
