Description

PN 554-114LW is a Holley EFI Dominator ECU that uses 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) or applications with high continuous current draw. It offers extensive capabilities, including integrated electronic transmission control, drive-by-wire throttle control, dual wideband oxygen sensor capability, and extensive inputs and outputs.
