Holley EFI 550-606N - HP EFI ECU And Harness Kit

HP EFI ECU And Harness Kit; Universal Ford V8 Multi-Point Fuel Injection; Incl. ECU/Harness; Incl. NTK Oxygen Sensor;

Looking for a alternative for your stock or built late model factory FORD EFI engine? How about a replacement ECU for your older Holley C950? Holley has you covered. HP EFI ECU and harness kits are designed to be used with popular factory EFI engines as an alternative to the factory ECU and harness or as a replacement for your C950 ECU. The HP allows you to accurately control the fuel and ignition of your engine along with additional controls for nitrous, boost or water meth.

• Unique lb/hr based fueling strategy greatly simplifies and commonizes tuning
• 4 Stage nitrous oxide control
• Integrated single channel wide band oxygen sensor control. Works with NTK or Bosch sensors
• Individual cylinder fuel and spark control allows you to unlock your engine’s potential
• Can be configured “Wet” or “Dry” with closed loop feedback
• Fully featured nitrous control eliminates the need for a separate nitrous controller device
• Integrated Water/Methanol injection control
• ECU is fully potted and can be mounted in the engine compartment or interior
• Eight 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
• 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
• Includes NTK wideband oxygen sensor
• 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
• Two channel knock control sensor Inputs for both one or two wire knock sensors
• 4 Programmable high or low Pulse Width Modulated (PWM) outputs and 4 fully configurable inputs can be configured for use
• 1-5 Bar MAP sensor capability
• Self-tuning fuel table strategy greatly simplifies tuning process
• Allows for use of common OEM sensors as well as customer sensor calibration input
• Speed density, Alpha-N, or combination fueling strategies
• Progressive control based on time, RPM, or boost, requires part # 554-111
• Advanced idle, closed loop, and enrichment strategies allow for very stable operation
• Dedicated fuel and oil pressure inputs
• Eight sequentially driven 8:2 peak and hold injector drivers, capable of driving up to 16 low or high impedance injectors as a standard feature. Multiple staged injector strategies
• Works with 4, 6, 8 cylinder engines
• Full timing retard/control configurability per stage based on RPM or time
• Lean or rich safety cutoff
• Sealed automotive and marine grade connectors
• Controls both stepper and PWM Idle Air Control (IAC) motors
• Custom settings can be configured to allow many other applications
• Turbo boost control
• 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.
• Internal data-logging standard with a huge 2GB of memory
• Plug and Play control of factory GM 24x and 58x LSx engines
• 4 Stage progressive nitrous control
