Holley Hp Efi Ecu

Looking for a hassle-free solution for your stock or modified late-model factory EFI engine? Holley has the perfect answer. The HP EFI ECU and harness kits serve as a direct replacement for the factory ECU and harness or as an upgrade for your older Holley C950 ECU. This versatile system provides precise control over fuel and ignition, offering additional functionalities like nitrous, boost, or water methanol controls.
