Well then, when is a custom map required? Custom maps can help achieve closer to 100% optimization on any
bike, but is that really necessary ? Generally no. A bike may be 60-70% optimized in standard form. With the
Power Commander and an available map from our database the bike may be 90-95% optimized. This constitutes
a huge gain in performance. Is it crucial to have the last 5-10% of optimization? It depends on what your goal is. If
every last bit of power is necessary then it can be. If what you want is a bike that runs considerably better than
standard without any additional adjustment then it is not. The point at which a custom map is really a necessity is
when the engine and or exhaust are heavily modified. When a bike has special cams, ported heads, and or a “one
off” exhaust system a custom map is the only way to fuel curve match the engine requirements.
