Description

The Range Technology RNGRA003B is an AFM/DFM Disabler designed for GM V8 and V6 engines. This device allows compatible vehicles to run in full-cylinder mode at all times, preventing the Active or Dynamic Fuel Management system from dropping cylinders. It simply plugs into the OBD-II port and disables the AFM system without reprogramming the factory ECU. The disabler also turns off the Auto Start/Stop feature and leaves no trace, allowing a return to factory settings by unplugging it.
