The HP Series EFI ECU Only from HOLLEY is a standalone engine control unit designed for vehicles requiring precision fuel injection management. This ECU is built for operators who demand reliable electronic fuel delivery in various environments, making it suitable for both military and specialty vehicle applications.
Engineered for vehicles already equipped with HP Series fuel injection components, this control module regulates fuel injection timing, duration, and pressure across the entire engine operating spectrum. Its compact architecture—measuring 7.8 x 3.2 x 9.7 inches and weighing just 3.8 pounds—enables flexible mounting in space-constrained installations.
Field mechanics, military maintenance teams, and specialty vehicle builders benefit most from this ECU-only configuration, which allows selective component replacement without a full system overhaul. Installation requires integration with existing fuel injectors, sensors, and other components to ensure optimal performance.
