Yoshimura Fuel Adjuster Box
The adjuster tool works in conjunction with the stock engine control module to reprogram the fuel mapping to tune modifications. Yoshimura's tool is AMA supersport legal and does not "trick" the stock ECM to change mapping nor does it have to remain installed on the motorcycle after tuning is complete. * Used in conjunction with OEM electronic control module (ECM) * Adjuster box connects to stock wiring harness and communicates with your ECM * The adjuster allows you to make fuel map adjustments to the slow speed circuit and low, medium and high throttle positions on the fuel injection map * Adjustments are made with a five-position switch; additional potentiometer fine-tunes the slow-speed circuit * Adjusts fuel metering from -10% injector duration to +10% injector duration in increments of +/-5% * Does not alter sensor input. Box adjusts ECM fuel map * This means your fuel injection will function properly at all elevations and in varying weather conditions
