Holley Electronic Fuel Injection Dominator Engine Control Unit.

The Dominator EFI Engine Control Unit 554-114 is intended for all engine applications, from street to unlimited high-end racing Mustangs, or C10, F-100, and Bronco applications. In addition to the transmission control, drive by wire, dual wideband oxygen sensor options and individual cylinder fuel and spark control, the Dominator system have nearly unlimited capabilities to control any power adder, input, or output you can throw at them. All inputs and outputs are programmed using an innovative new “Pin Mapping” strategy that allows inputs and outputs to be pinned to the user’s discretion, preventing wasted inputs and outputs by non-used dedicated functions. 

Features and Benefits:
- Works with 4, 6, 8, and 10 Cylinder Engines
- Integrated Electronic Transmission Control (GM 4L60E, GM 4L80E, Ford AODE, 4R70W)
- Integrated Drive by Wire Throttle Body Control
- Integrated Dual Channel Wide Band Oxygen Sensor Controls
- Controls Both Stepper and Idle Air Control Motors
- (2) Channel Knock Control Sensor Inputs for Both One or Two Wire Knock Sensors
- (12) Sequentially Driven 8:2 Peak and Hold Injector Drivers
- (12) Channel Distributorless Ignition Outputs Capable of Directly Driving “Smart” Ignition Coils or Holley DIS Coils
- Unique lb/hr Based Fueling Strategy for “Quick Start” Engine Starts
- Advanced Idle, Closed Loop, and Enrichment Strategies Allow for very Stable Engine Operation
- 1-7 Bar MAP Sensor Capability (Naturally Aspirated or Boosted Applications)
- Fuel Map and Learn Function Smoothing
- Store and Select Between Four Calibrations with Multi Map Selector
- Allows for Use of Common OEM Sensors as well as Custom Sensor Calibration Input
- Dedicated Fuel and Oil Pressure Inputs
- Data Logger, Strip Chart For Real-Time Data Viewing, Fully Configurable Lap Top Gauge Panel
- 8-Stage Fully Featured Nitrous Oxide Control
- “Wet” or “Dry” Dominator Configurations with Closed Loop Feedback
- Full Timing Retard/Control Configurability per Stage Based on RPM or Time
- Integrated Water/Methanol Injection and Turbo Boost Control
- Lean or Rich Safety Cutoff
- “Boost Builder” Functions
- Advanced Tuning ICF Features Fully User Configurable tables, 1D, 2D, 1D Per Gear, 2D Per Gear

- 13 - “Multi-Inputs” – 0-5V sensor input, 0-20v sensor input, thermistor temperature input, or high or low voltage input
- 30 - 0-5V Sensor Inputs – 0-5V sensor or used as switched high or low inputs
- 4 - Speed Inputs – Digital (square wave) input or an inductive input
- 20 - 12v PWM Outputs – PWM or switched 12V outputs. Rated at 2A maximum
- 16 - Ground PWM Outputs – PWM or switched ground outputs. Rated at 2A maximum

*Configurable for Dual Cooling Fans (including brushless fans that require PWM signal), dual fuel pumps, AC inputs, basic TCC lockup, and multiple timing retard inputs

*User Programmable Caution and Warning Outputs for all Sensors. Ignition Plug and Play with GM LS Engines (non-VVT), GM HEI, Ford TFI, Coyote (non-VVT), 4.6/5.4 Mod Motor, Late Model HEMI and Magnetic and Hall Effect Trigger.

With simplified tuning strategies, the Dominator feature allows for virtually unlimited dimensional tuning of fuel, spark, boost, nitrous and more. The user is still capable of modifying the fuel, timing, boost, nitrous, individual cylinder, ignition dwell, and DBW since the advanced tuning adjusts parameters based on any input, sensor, or time.


Need to run a turbocharged, nitrous injected 8-cylinder running water-methanol injection? No problem with Dominator EFI. There are enough inputs and outputs to allow the Dominator VMSs to serve as their own data acquisition and control module. The Dominator VMS will eliminate the need for additional controllers as they are all contained in this one unit. The only thing limiting the Dominator Engine Control Unit is your imagination!
