PN 554-114LW is a Holley EFI Dominator ECU which utilizes 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), and applications with high continuous current draw.

Features:

Lightweight ECU potting reduces overall ECU weight by 1.8 LBS or 34% (3.53 LBS) – Perfect for applications where saving every oz is mission critical
Works with 4, 6, 8 and 10 cylinder engines
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 wide band 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. Will drive 2 wire coils with the addition of PN 554-112 high current coil driver module
Speed density, Alpha-N, Alpha-N Combination, and VE fueling strategies – 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 lb/hr 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 tuning process – The more you drive it, the more it learns
“Quick Start” 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 both 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)
Store and select between four calibrations with Multi Map Selector (Part Number 558-407)
HARDWARE
ECU is fully potted and can be mounted in the engine compartment or interior – See images for dimensions
Sealed automotive and marine grade connectors
Optional Digital Displays - 7" Digital Dash (PN 553-106) / 3.5" Touch Screen LCD (PN 553-108)
12.3" Pro Dash (PN 553-111) and 7" Race Dash (PN 553-106) features full gauge layout customization, and nearly limitless tuning options.
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
Can be configured “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 to allow the user to enter water/meth flow as a percentage of fuel injector flow for water/meth tuning precision 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
Fully featured boost control capability eliminates the need for a separate boost control 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 assist building boost on the starting line by altering ignition timing, fueling, as well as nitrous oxide activation. Can also be used as an anti-lag function
INPUTS AND OUTPUTS
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 as well as 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 innovative new “Pin Mapping” strategy that allows inputs and outputs to be pinned as desired by the user, allowing for inputs and outputs to not be “wasted” by non-used dedicated 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
ADVANCED TUNING ICF
Fully User Configurable tables, 1D, 2D, 1D Per Gear, 2D Per Gear
Tables allow for virtually unlimited dimensional tuning of fuel, spark, boost, nitrous and more
User can modify fuel, timing, boost, nitrous, individual cylinder, ignition dwell, DBW, and more
Parameters can be adjusted based on any input, sensor, or time.

When utilizing a Transbrake, it is mandatory to install either a relay or, our Transbrake input protection device. P/N 554-128. This will protect the ECU from any flyback voltage when the Transbrake is released. Dominator EFI systems are sold "a la carte". The following must be purchased for a complete system: ECU (includes software and programming cable), Main Power Harness, Wideband Oxygen Sensor, Main Engine Wiring Harness, Injector Wiring Harness, Ignition Adapter Harness and Accessories. Certified to ISO 8846, SAE J1171 & United States Coast Guard Requirements for Ignition Protection & Fire Resistance.
