Holley Dominator EFI ECU

Holley® has been the undisputed leader in racing fuel systems for over 100 years. Holley carburetors powered every NASCAR® Sprint® Cup team and nearly every NHRA® Pro–Stock champion for four decades. Now, Holley Racing EFI products power these cars and are dominating the race performance world. Holley products for GM’s popular LS engine are dominating the LS scene as well. Holley’s products also include racing performance fuel pumps, intake manifolds & engine dress–up products for street performance, race and marine applications. As a single solution, or partnered with products from other Holley companies we can give you the racing edge you need over the competition!

The Holley Dominator is the new standard in Racing EFI ECU with virtually unlimited capabilities!  Integrated electronic transmission control, drive by wire throttle control, dual wideband oxygen sensor capability, an extensive number of inputs and outputs for various control combinations, and much more.

Features:

• This racing EFI ECU unit works with 4, 6, 8 and 10 cylinder engines.

• Furthermore, this unit has Integrated drive by wire throttle body control. This unit can control two drive by wire throttle bodies. This unit is compatible with a number of DBW throttle bodies including GM, Chrysler, Ford, and Nissan
• Integrated dual channel wide band oxygen sensor controls are included. These controls are for monitoring both engine banks (NTK or Bosch sensors)
• Additionally, an extensive number of inputs and outputs allow for a limitless combination of options. This unit can be used as a complete data acquisition system as well.
• Also, unit comes with Twelve sequentially driven 8:2 peak and hold injector drivers. These injector drivers are capable of driving up to 24 low or high impedance injectors.  Thus, allowing multiple staged injector strategies.
• In addition, twelve channel Distributorless Ignition (DIS) outputs capable of directly driving “Smart” ignition coils or Holley DIS coils are provided. Thus, this unit will drive 2 wire coils with the addition of the PN: 554-112 high current coil driver module.

Additional Features

• This unit provides Speed density, Alpha-N, Alpha-N Combination, and VE fueling strategies. Thus, this Tuner has the option to select from a variety of load sensing strategies to meet the engine requirements or tuning preference.
• In addition, Individual cylinder fuel and spark controls allow you to unlock your engine’s potential.
• Unique lb/hr based fueling strategy greatly simplifies and commonizes the tuning process.
• Thus, advanced idle, closed loop, and enrichment strategies, allow for very stable engine operation.
• Also, 1-7 Bar MAP sensor capability used for naturally aspirated or boosted applications.
• Thus, the Fuel Map and Learn Function Smoothing process helps to smooth rough areas of the maps.
• The configurable User Password Protection “Lock” provided, allows you to prevent tampering with the tune.
• Self-tuning fuel table strategy greatly simplifies tuning process. The more you drive it, the more it learns.
• “Quick Start” strategies allow for faster engine starting.
• This unit allows for use of common OEM sensors as well as custom sensor calibration inputs.
• Thus, two channel knock control sensor inputs provide for both, one or two wire knock sensors.
• Also, dedicated fuel and oil pressure inputs are provided.
• Controls both Stepper and PWM Idle Air Control (IAC) motors.
• Also, 3 Rev Limiters allow you to choose between 4 options for each: Fuel Only, Spark Only, Fuel and Spark, or Soft.
• Additionally, Traction Control allows power reduction via timing, Nitrous percentage or boost (Requires Davis Technologies Holley Module).
• Additionally, you can store and select between four calibrations with the Multi Map Selector (Part Number 558-407).

• HARDWARE

• The ECU is fully potted and can be mounted in the engine compartment or interior, See images for dimensions.
• Also, the unit has sealed automotive and marine grade connectors.
• Optional Digital Displays – 7″ Digital Dash (PN 553-106) / 3.5″ Touch Screen LCD (PN 553-108) are available.
• Finally, the 7″ Race Dash (PN 553-106) features full gauge layout customization, and nearly limitless tuning options.
• Also, optional LED gauges (Part numbers 553-100 and 553-101) eliminate the need for additional sending units.

• DATA VISUALIZATION TOOLS

• Data Logger –Analyze and export your data with sophisticated, but user friendly tools – Internal logger has 4 GB of memory
• Strip Chart – For real-time data viewing
• Fully Configurable lap top Gauge Panel – Life-like gauge cluster on your laptop screen
• Racepak Integration Module Available.
• Data logger – Smoothing, multiple graph view, pre-defined notes fields and more..

• 8 STAGE NITROUS OXIDE CONTROL

• Fully featured nitrous control eliminates the need for a separate nitrous controller device
• Configure the nitrous Oxide Control as “Wet” or “Dry” with closed loop feedback
• Progressive control based on time, RPM, or boost, requires part # 554-111
• Lean or rich safety cutoff
• Full timing retard/control configurability per stage based on RPM or time

• INTEGRATED WATER/METHANOL INJECTION CONTROL

• Uses Holley water/meth solenoids specially designed and calibrated for use with this EFI system. This will allow the user to enter water/meth flow as a percentage of fuel injector flow for water/meth tuning precision that is unmatched in the industry.
• Allows for two nozzles to be controlled.
• Nozzles available from 400 to 1000 cc/min.
• Complete control of pump activation, and low system safety features.

• TURBOCHARGER BOOST CONTROL

• Also, fully featured boost control capability eliminates the need for a separate boost control device.
• Finally, configure the unit to control boost based on time, gear, speed or manual inputs.
• In addition, gear based boost control is configurable using several different methods.
• “Boost Builder” functions offer the ability to assist building boost on the starting line by altering ignition timing, fueling, as well as Nitrous oxide activation and an anti-lag function.

• INPUTS AND OUTPUTS

• Also, Configure the 13 “Multi-Inputs” as a 0-5V sensor input, 0-20v sensor input, thermistor temperature input, or high or low voltage input.
• Configure the 30  0-5V Sensor Inputs for 0-5V sensors, and some can be used as switched high or low inputs.
• Also, configure the 4 Speed Inputs as a digital (square wave) input or an inductive input.
• Configure the 20 12 VDC PWM Outputs as PWM or switched 12 VDC outputs rated at 2 Amps Max.
• Configure the 16 Ground outputs as PWM or Switched ground outputs rated at 2 Amps Max.
• Furthermore, all inputs and outputs are programmed using an innovative “Pin Mapping” strategy. This strategy allows the user to map pins as desired by inputs and outputs  . Thus, allowing for inputs and outputs to not be “wasted” by unused dedicated functions.
• Configurable for: dual cooling fans (including brushless fans that require PWM signal).  Configurable for: dual fuel pumps, AC inputs, basic TCC lockup, and multiple timing retard inputs.
• User programmable caution and warning outputs for all sensors.
