With Wiseco's new fuel controller, you can add and subtract fuel in your dirt bike. The fuel-management controller will allow you to fine-tune your bike's EFI fuel delivery to maximize the performance of other modifications to your bike, such as high-compression pistons, exhaust, intake, or camshafts. Wiseco says that these controllers are simple to use, and you don't need a dyno or a computer. With the touch of a button, you can adjust three basic  zones of operation, similar to a carburetor: a "pilot jet" zone to set your idle and cruise; a "needle jet" zone for acceleration; and a "main jet" zone for heavy loading and wide open throttle. Wiseco has its new line of fuel controllers ready to ship for the 2009 Honda CRF450R, Kawasaki KX450F, and Suzuki RM-Z 450 dirt bikes, with more to come.
