Description
The Range Technology RA003B AFM/DFM Disabler lets a V6 or V8 General Motors vehicle run on all cylinders, all the time. It stops the factory Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems from dropping cylinders, removing the cylinder-deactivation shudder and giving more consistent throttle response.
Installation takes seconds and needs no tools: plug the module into the vehicle’s OBD-II port and it begins working immediately. It does not reprogram the factory ECU and leaves no trace — unplug it at any time to return the vehicle to original factory settings, which helps protect the factory warranty. It can also be moved to another compatible GM vehicle.
Compatibility: V6 and V8 GM cars, trucks and SUVs equipped with Active or Dynamic Fuel Management. Colour: Blue. Model: RA003B. Dimensions: approx. 10.2 × 10.2 × 2.5 cm.
