Dyna FS Fuel and Ignition Module

The Dynatek Dyna FS Fuel & Ignition Module is designed to elevate the performance of 2004-2009 Yamaha YFZ450 ATVs. This unit combines both fuel and ignition control into a single device, featuring factory connectors for a straightforward, direct plug-in installation. Champion racers worldwide trust this module to help their ATVs achieve peak performance. The Dyna FS module unlocks your ATV's full potential by offering improved timing curves and a higher rev limit, surpassing stock performance capabilities. It also includes a 2-position map switching function, allowing for on-the-fly adjustments. For advanced tuning, users can self-tune using the DynaTune autotune kit or utilize existing Power Commander maps. The module enhances spark energy, leading to easier starting and improved fuel burn, as well as providing increased throttle response. It also removes the reverse rev limit and overrides the belt indicator to ensure full performance is accessible at all times. Fitment includes the Yamaha YFZ450 models from 2004 through 2009, as well as the YFZ450 Bill Balance Edition (2006-2007), YFZ450 SE (2007-2008), YFZ450R (2009), and YFZ450R SE (2009).
