Throttle Assy.

Product Details:

The electronically controlled carburetor was an intermediate step between analog carburetor controls (vacuum or temperature operated devices…or even cable-operated like an old manual choke) and electronic fuel injection. The main advantages that ECC brought were:

-Idle speed control. The control module can allow extra air through the carb to keep the engine from bogging down or stalling when the idle speed gets too low, for instance when adding load from switching on the air conditioner.

-Mixture control. This allows the vehicle to meet emission standards by keeping the air/fuel ratio optimal for combustion, and for catalytic converter efficiency. It also allows a richer mixture during cold start and high acceleration (wide open throttle).

In the US in the early 1980s, most ECC also came with spark control. A “map” of spark timing would look up the best spark advance value depending on things like coolant temperature, throttle position, engine vacuum (that is, manifold pressure) plus maybe some other sensor inputs that I don’t remember.

All that stuff allowed vehicles to meet emission standards while maintaining reasonable fuel economy and drivability.
