The BRC Sequent 56 is a highly reliable sequential gaseous injection system designed for 3-cylinder and 4-cylinder engines. It manages fuel injection via an electronic control unit (ECU) that communicates directly with the vehicle's original OBD system. To diagnose errors, modify injection maps, or update firmware, you must use the proprietary BRC calibration software on a Windows computer. Before You Download: Required Hardware
