Feedback Carburetor Air/Fuel Control


The feedback carburetor air/fuel mixture is constantly controlled by the ECU. The ECU monitors input data from the various sensors to calculate fuel flow required to yield desired air/fuel ratios. The fuel flow may also be modified for specific operating conditions such as hot or cold starts, acceleration or deceleration.
