Overview

The Holley Dominator Lightweight EFI ECU (554-114LW) is a high-performance engine management system designed for serious drag racing applications. It offers the same advanced capabilities as the standard Dominator ECU — including sequential fuel and spark control, integrated transmission control, dual wideband O2, drive-by-wire, boost, and nitrous control — but uses a lighter potting material that reduces overall weight by 1.8 lbs (approximately 34%). Ideal for weight-sensitive race builds where every ounce matters. Not recommended for under-hood or high continuous current applications.

Features

  • Lightweight potting reduces weight by 1.8 lbs (to 3.53 lbs)
  • Specifically designed for drag racing applications
  • Supports 4, 6, 8, and 10 cylinder engines
  • 12 sequential injector drivers (up to 24 injectors)
  • 12-channel distributorless ignition outputs
  • Integrated electronic transmission control (GM 4L60E/4L80E, Ford AODE/4R70W)
  • Dual channel wideband oxygen sensor control
  • Drive-by-wire throttle body control (up to 2)
  • Built-in boost, nitrous, and traction control capability
  • Extensive programmable inputs and outputs
  • Internal data logging
