An adjustable fuel controller that improves the stock fuel injection map once a rider has modified his air box, air fi lter, or purchased an aftermarket exhaust. The adjustable fuel mapping includes three turnable modes depending on terrain, weather, and riding conditions. The Mod Box is easy to install and will instantly provide performance gains for fuel injected models. Fuel injection is a step forward but stock mapping is jest the, stock mapping. If racers choose to modify their ATV or bike, the stock fuel map needs to be reprogrammed to receive the greatest benefit from these modifications. DRD accomplishes this by re-mapping the stock program, testing a variety of applications and selecting the best map for each model. When a map has passed DRD’s Dustin Nelson and Doug Dubach test, the map is programmed into the product-specifi c DRD Mod Box. Better throttle response, more power, faster top speed, and the convenience of a pre-programed, thoroughly tested, yet adjustable system, the Mod Box is an
essential upgrade for all customers with fuel-injected motorcycles or ATVs.
