CDI & ECU

Your fuel-injected cruiser is equipped with an ECU (electronic control unit) that's programmed to deliver fuel to the motor based on an air/fuel ratio for a stock air filter and stock exhaust system. While the ECU can self-adjust for environmental factors such as temperature and altitude, it can't adjust for mechanical changes like adding performance parts. When you install a performance exhaust system, your airflow changes, so you need a fuel management system that adjusts your air/fuel ratio to match the changes. That fuel management system is Fuelpak. The perfect combination with your...

The Fuelpak FP3 will revolutionize fuel management for all new Harley-Davidson models now using the HDLAN (CAN Bus) system. Connecting wirelessly by Bluetooth to iPhone or Android smartphones, Fuelpak FP3 uses Flash technology to recalibrate engine parameters and mapping for exhaust systems and other performance upgrades downloaded from the expansive library of calibrations developed by Vance & Hines. Also standard for the Fuelpak FP3 is an Autotune feature, making use of all factory sensors to add another layer of precision tuning for specific requirements, whether tuning for unique...
