My caravan 1987 2.2L 4cyl does have 2 barrel carb (Tulip).
Did have computer to adjust the spark advance via the rpm (sensed via
the distributor vanes) and vacuum transductor. Computer also monitor
engine temp, control the throttle kicker (bumps up 200rpm or so).
Throttle closed contact. Computer also controls the secondary
throttle via vacuum soleoid valve, enables when engine is warmed up.
 For fuel vapor control too, via another vacuum soleoid valve.

Micro in radio for electronic tuner & clock.
