Holley EFI 554-114LW - EFI Lightweight Dominator ECU

Holley EFI - 554-114LW

Holley EFI Lightweight Dominator ECU

Dominator EFI ECU; Lightweight;

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.
