The BMS JB4 FSB Water Injection controller allows the JB4 to control your WMI pump and solenoid for dynamic progressive flow mapping. It also allows the JB4 to monitor pump current to overlay it with CANbus feedback for tuning parameters such as fuel trims and fuel pressure to provide a comprehensive flow based safety system.
