Holley 554-114 - Holley HP EFI 4bbl Throttle Body Fuel Injection Systems Details

ECU & Harness

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

Plug and Play control of factory GM 24x and 58x LSx engines I

ntegrated electronic transmission control. Controls GM 4L60E and 4L80E transmissions with more to come in the future

Integrated dual channel wide band oxygen sensor controls. Works with NTK or Bosch sensors. More channels can be added via CAN bus

Integrated drive by wire throttle body control. Can control two drive by wire throttle bodies

4 stage progressive nitrous control

Turbo boost control

Integrated water/methanol injection control

Integrated "Data Acquisition and Control" allowed with massive amount of programmable inputs and outputs

Internal data-logging standard with a huge 2GB of memory

Self-tuning fuel table strategy greatly simplifies tuning process

Store and change between four calibrations

Individual cylinder fuel and spark control allows you to unlock your engine's potential

Optional 5.7" full-color touchscreen LCD allows easy on-the-fly tuning, data-logging or can be used as an easy to see graphical gauge panel

Unique lb/hr based fueling strategy greatly simplifies and commonizes tuning

Advanced idle, closed loop, and enrichment strategies allow for very stable operation

ECU is fully potted and can be mounted in the engine compartment or interior

Sealed automotive and marine grade connectors

Works with 4, 6, 8 and 10 cylinder engines

Allows for use of common OEM sensors as well as customer sensor calibration input

1-5 Bar MAP sensor capability

Ignition Plug and Play with GM 24x and 58x LSx engines, GM HEI, Ford TFI, magnetic and hall effect trigger, and other ignition systems. New Plug and Play applications in process. Custom settings can be configured to allow many other applications.

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

Speed density, Alpha-N, or combination fueling strategies

3 Rev Limiters

Massive 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.

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.

4 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. Also can be used as an anti-lag function

User configurable input and output programming

Outputs can be programmed as pulse width modulated or switched.

Unique circuitry allows inputs to be programmed as speed/frequency, 0-5V, 0-20V, thermistor, or switched high or low

User configurable inputs and outputs can be programmed to have a variety of different inter-dependencies

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.

Replace your carburetor with a "Bolt on and Go" TBI system that also allows you to tune as well HP EFI throttle body kits are a direct replacement for a square flange carburetor. Plug and play connectors make installation a snap and by utilizing a laptop (or the optional 5.7" full color touch screen LCD) along with the HP's self-tuning capabilities, you will be up and running in no time. Come with most all parts necessary for a complete installation including throttle body, ECU, wiring harness and sensors. Fuel pump available separately to fit your requirements.
