Range Technology UK – AFM & DFM Disabler Modules

Range Technology produces plug-in modules designed to disable Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems on GM vehicles. These systems can cause unwanted engine behaviour, such as lifter failures or inconsistent performance. Range modules provide a simple, safe solution to keep your V8 running on all cylinders, all the time.

Why Range Technology?

  • Plug-and-Play: Simply plug the module into the OBD-II port – no permanent changes required.
  • Improved Reliability: Eliminates AFM/DFM cylinder deactivation to protect lifters.
  • Enhanced Driving Experience: Keeps your engine smooth and predictable.
