Your fuel injected American V-Twin 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 performance exhaust system.
The Fuelpak LED and LCD models are plug-and-play fuel controllers providing custom-tailored fuel mapping for all Delphi fuel injected HD models using SAE J1850 connectors and certain HDLAN connector models, that install in-line with the ECM and modify the output signal to the fuel injectors.
