Holley EFI Lightweight Dominator ECU 554-114LW

Holley EFI Dominator ECU 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 only. 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); recommended for applications where saving ounces is critical.
- 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 trigger.
- 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.
- Integrated Drive by Wire Throttle Body Control – Able to control two drive by wire throttle bodies compatible with GM, Chrysler, Ford, and Nissan DBW throttle bodies.
- Integrated dual channel wide band oxygen sensor controls – Monitor both engine banks (NTK or Bosch sensors).
- Extensive amount of inputs and outputs allow for limitless combination of options and allows the unit to be used as a complete data acquisition system.
- 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 available.
- Individual cylinder fuel and spark control allows you to unlock your engine’s potential.
- Unique lb/hr based fueling strategy greatly simplifies and standardizes 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 smooth rough areas of the maps.
- Configurable user password protection to lock your tune and prevent tampering.
- Self-tuning fuel table strategy greatly simplifies tuning process.
- “Quick Start” strategies allow faster engine starting.
- Allows 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 with options for 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).
- ECU is fully potted and can be mounted in the engine compartment or interior.
- Sealed automotive and marine grade connectors.

- Nitrous Control:
- Fully featured nitrous control eliminates the need for a separate nitrous controller device.
- Can be configured NOS “Wet” or “Dry” with closed loop feedback.
- Progressive control based on time, RPM, or boost (requires part number 554-111).
- Lean or rich safety cutoff.
- Full timing retard/control configurability per stage based on RPM or time.
- Uses Holley water/meth solenoids designed and calibrated for precise water/meth injection control.

- Turbocharger Boost Control:
- Fully featured boost control 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 assist building boost on the starting line by altering ignition timing, fueling, or nitrous activation.

- Inputs and Outputs:
- 13 Multi-Inputs configurable as 0-5V sensor input, 0-20V sensor input, thermistor temperature input, or high/low voltage input.
- 30 0-5V sensor inputs for sensor monitoring or switched high/low inputs.
- 4 Speed inputs configurable as digital square wave or inductive input.
- 20 12V PWM outputs configurable as PWM or switched 12V outputs rated at 2A maximum.
- 16 Ground PWM outputs configurable as PWM or switched ground outputs rated at 2A maximum.
- Innovative “Pin Mapping” strategy allows inputs and outputs to be assigned as desired by the user.
- Configurable for dual cooling fans, 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 including 1D, 2D, 1D per gear, and 2D per gear.
- Tables allow virtually unlimited dimensional tuning of fuel, spark, boost, nitrous and more.
- Users can modify fuel, timing, boost, nitrous, individual cylinder control, ignition dwell, drive by wire, and more.
- Parameters can be adjusted based on any input, sensor, or time.
