Holley 534-55 Replacement Electronic Control Unit for 1 and 2-Barrel Digital Pro-Jection Systems

This replacement electronic control unit is designed to retro-fit carbureted, non-computerized, V-8 equipped vehicles and boats. A temperature sensor positioned in the water jacket provides the unit with accurate and timely fuel enrichment information for quick start-ups on cold engines. A distribution ring rests on the air cleaner flange to direct incoming air flow to the throttle bores for increased efficiency. It is for use on 1 and 2-barrel digital projection systems and can be mounted on any flat surface.
