Open Loop engines have the same components as closed loop, except the ECU and oxegen sensor and muffler are not included.
Closed Loop - This system relies upon two critical parts: an analog Electronic Control Unit (ECU) and an oxygen sensor. The system's fuel metering valve, installed in the fuel line, is activated by the ECU to provide either less or more fuel. The ECU engages when the oxygen sensor, installed in the exhaust, signals a change in oxygen levels. In this way, the ECU maintains a consistent air to fuel ratio at all loads and speeds
