Range DFM Module

Range Technology DFM Module

Your GM Refresh V8 has eight cylinders for a reason, and the Range Technology DFM Module makes sure all of them stay in the fight. It's the first product on the market to tackle Dynamic Fuel Management in these trucks, and it does it the right way -- a direct plug-in to your ECM that takes minutes and requires zero tools, zero tuning, and zero permanent changes to your truck. DFM and Auto Start/Stop are both gone, and your engine runs the way it should have from the factory. Headed to the dealer? Unplug it, walk in clean. Just plug it in behind the driver's front wheel well liner and drive. For 5.3L and 6.2L GM Refresh owners who are tired of their truck second-guessing them, this is the fix.

Range Technology DFM Pro (New)

The DFM Module already solved the problem. The DFM Pro takes it further. Built on the same proven RA007 platform, DFM Pro adds Bluetooth connectivity and a smartphone interface that gives you real-time throttle response tuning, live engine data, and the ability to read and clear trouble codes without a separate scan tool. Everything you needed used to require multiple products. Now it's one plug. Installation is still the same five-minute plug-and-play job. No wiring, no tuning, no modifications. But now you've got a window into what your engine is actually doing, and the ability to dial in pedal feel on the fly. If you already know what the DFM Module does for your truck, the Pro is the version you actually want.
