Dominator® EFI Vehicle Management Systems are intended for all engine applications, from street to unlimited high-end racing applications. In addition to the transmission control, drive by wire, and dual wideband oxygen sensor options, Dominator® systems have nearly unlimited capabilities to control any power adder, input, or output you can throw at them. Need to run a turbocharged, nitrous-injected 8 cylinder running water-methanol injection? No problem with Dominator® EFI. How about control a 4L60E transmission as well as the fuel and spark on your street rod? No problem. There are also 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 one unit. The only thing limiting the Dominator® Vehicle Management System is your imagination!

Holley Dominator EFI features:

  • Works with 4, 6, 8 and 10 cylinder engines
  • 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 triggers. Custom settings can be configured to allow for use with many other applications
  • Integrated electronic transmission control. Operates GM 4L60E and 4L80E transmissions, Ford AODE and 4R70W with more to come in the future
  • Integrated drive by wire throttle body control. Can control two drive by wire throttle bodies. Compatible with a number of DBW throttle bodies including GM, Chrysler, Ford, and Nissan
  • Integrated dual-channel wideband oxygen sensor controls. For monitoring both engine banks (NTK or Bosch sensors)
  • Extensive amount of inputs and outputs allow for limitless combination of options. Allows for unit to be used as a complete data acquisition system as well
  • Twelve sequentially driven 8:2 peak and hold injector drivers, capable of driving up to 24 low or high impedance injectors as a standard feature. Multiple staged injector strategies
  • Twelve channel distributorless ignition (DIS) outputs capable of directly driving “smart” ignition coils or Holley DIS coils
  • Speed density, Alpha-N, Alpha-N Combination, and VE fueling strategies. The tuner has the option to select from a variety of load sensing strategies to meet their engine requirements or tuning preference
  • Individual cylinder fuel and spark control allows you to unlock your engine’s potential
  • Unique lbs per hour based fueling strategy greatly simplifies and commonizes tuning
  • Advanced idle, closed loop and enrichment strategies allow for very stable engine operation
  • 1-7 bar MAP sensor capability for naturally aspirated or boosted applications
  • Fuel map and learn function smoothing. Helps to smooth rough areas of the maps
  • Configurable user password protection. Lock your tune to prevent tampering
  • Self-tuning fuel table strategy greatly simplifies the tuning process. The more you drive it, the more it learns
  • Quickstart strategies for faster engine starting
  • Allows for use of common OEM sensors, as well as custom sensor calibration input
  • Two channel knock control sensor inputs for one or two wire knock sensors
  • Dedicated fuel and oil pressure inputs
  • Controls both stepper and PWM idle air control (IAC) motors
  • 3 rev limiters. Choose between 4 options for each: Fuel only, spark only, fuel and spark, or soft
  • Traction control – Allows power reduction via timing, nitrous percentage or boost (Requires Davis Technologies Holley Module)


  • ECU is fully potted and can be mounted in the engine compartment or interior
  • Sealed automotive and marine grade connectors
  • Optional digital displays include 7" digital dash or 3.5" LCD touchscreen LCD
  • 7" race dash features full gauge layout customization and nearly limitless tuning options
  • Optional LED gauges eliminate the need for additional sending units


  • Data Logger – Analyze and export your data with sophisticated, user-friendly tools. The internal logger has 4 GB of memory. Smoothing, multiple graph view, pre-defined notes fields and more
  • Strip Chart – For real-time data viewing
  • Fully configurable laptop gauge panel
  • Racepak integration module available.


  • Fully featured nitrous control eliminates the need for a separate device
  • Can be configured wet or dry with closed loop feedback
  • Lean or rich safety cutoff
  • Full timing retard and control configurability per stage based on RPM or time


  • Uses Holley water-methanol solenoids specially designed and calibrated for use with this EFI system to allow the user to enter water-methanol flow as a percentage of fuel injector flow for water-methanol tuning precision
  • Allows for two nozzles to be controlled
  • Nozzles available from 400 to 1000 cc per min
  • Complete control of pump activation and low system safety features


  • Fully featured boost control capability eliminates the need for a separate device
  • Can be configured to control boost based on time, gear, speed, and manual inputs
  • Gear-based boost control configurable by several different methods
  • Boost builder functions offer the ability to alter ignition timing, fueling, and nitrous oxide activation. Can also be used as an anti-lag function


  • 13 Multi-Inputs – Can be configured as a 0-5V sensor input, 0-20v sensor input, thermistor temperature input, or high or low voltage input
  • 30 0-5V Sensor Inputs – Configures any 0-5V sensor. Some can be used as switched high or low inputs
  • 4 Speed Inputs – Can be configured as a digital (square wave) input or an inductive input
  • 20 12v PWM Outputs – Can be configured as PWM or switched 12V outputs. Rated at 2A maximum
  • 16 Ground PWM Outputs – Can be configured as PWM or switched ground outputs. Rated at 2A maximum
  • All inputs and outputs are programmed using an innovative pin-mapping strategy that allows inputs and outputs to be pinned anywhere, allowing for inputs and outputs to not be wasted on unused functions
  • 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


  • Fully configurable tables, 1D, 2D, 1D per gear, 2D per gear
  • Tables allow for virtually unlimited dimensional tuning of fuel, spark, boost, nitrous and more
  • Ability to modify fuel, timing, boost, nirtrous, individual cylinder, ignition dwell, DBW, and more
  • Parameters can be adjusted based on any input, sensor, or time
