No electronics are involved. This is a mechanical system. Vacuum from the engine pulls the air metering plate open which moves a piston in the mechanical fuel head to feed the engine more fuel.
Ideally the BOV is plumbed between the air metering assembly and right before the throttle body. Air is recirculated when the valve is open so that air is seen by the system.
