Description

Holley EFI Lightweight Dominator ECU PN 554-114LW is a Holley EFI Dominator ECU which utilizes a lighter potting material than the standard Dominator unit (reduces total weight by 1.8 lbs). This lightweight version is specifically intended for drag racing. It is not recommended for use in high-heat conditions (under-hood mounting installations), and applications with high continuous current draw. When utilizing a Transbrake, it is mandatory to install either a relay or, our Transbrake input protection device. P/N 554-128. This will protect the ECU from any flyback voltage when the Transbrake is released. Dominator EFI systems are sold "a la carte". The following must be purchased for a complete system: ECU (includes software and programming cable), Main Power Harness, Wideband Oxygen Sensor, Main Engine Wiring Harness, Injector Wiring Harness, Ignition Adapter Harness and Accessories. Certified to ISO 8846, SAE J1171 & United States Coast Guard Requirements for Ignition Protection & Fire Resistance.
