AFM-DFM Disabler

Full Power

  • No more shuddering as your engine cycles between running on half or all cylinders
  • Improved power at light throttle with all cylinders firing which can actually result in improved fuel economy depending on your driving habits
  • GM's troublesome AFM valve lifters will no longer be tasked with activating and deactivating constantly, saving you money on costly future repairs

The Range AFM/DFM Disabler keeps you in full power 100% of the time.

Fast and Easy Setup

  • No tools needed
  • Simply remove it if uninstallation is necessary
  • No mechanical ability is needed, if you can plug something into the wall in your home, you can install and uninstall this without issue

Simply plug the module into your OBD-II port and it instantly disables the AFM or DFM system

All-Terrain

  • When the roads are covered in snow, you'll have the power to charge through and make it home
  • If your travels take you off the beaten path, you'll have the power to emerge on the other side unscathed
  • When hauling heavy loads, you need all the power you can get

The power and control you need in any situation

Safe and Reversible

  • Leaves no trace after uninstallation; your warranty is safe with Range
  • Simply unplug it to return to factory settings
  • If you're trading your trusty GM vehicle in on a newer model that's also equipped with AFM, take your Range with you and plug it into your new vehicle

Our AFM/DFM disabler does not reprogram the factory ECU
