Looking for an alternative for your stock or custom-built late model factory FORD EFI engine? Holley has the solution. The HP EFI ECU and harness kits are meticulously designed to seamlessly integrate with popular factory EFI engines, providing a reliable alternative to the factory ECU and harness or serving as a replacement for your older Holley C950 ECU. The HP system empowers you to precisely control the fuel and ignition of your engine, with additional capabilities for nitrous, boost, or water-meth controls.
Features:
- Optional 5.7” full-color touchscreen LCD for easy on-the-fly tuning, data-logging, or as a graphical gauge panel.
- Eight sequentially driven 8:2 peak and hold injector drivers, capable of handling up to 16 low or high impedance injectors with multiple staged injector strategies.
- Eight channel Distributorless Ignition (DIS) outputs capable of directly driving “Smart” ignition coils or Holley DIS coils. Can drive 2 wire coils with the addition of PN 554-112 high current coil driver module.
- Plug and Play control compatible with factory GM 24x and 58x LSx engines.
- Integrated single-channel wideband oxygen sensor control, compatible with NTK or Bosch sensors.
- Internal data-logging as a standard feature with a generous 2GB of memory.
- 4 Stage progressive nitrous control, turbo boost control, and integrated water/methanol injection control.
- Self-tuning fuel table strategy for a simplified tuning process.
- Individual cylinder fuel and spark control for unlocking your engine’s potential.
- Compatibility with 4, 6, and 8 cylinder engines.
- Unique lb/hr based fueling strategy simplifying and standardizing tuning.
- Advanced idle, closed-loop, and enrichment strategies for stable operation.
- Fully potted ECU for flexible mounting in the engine compartment or interior.
- Sealed automotive and marine-grade connectors ensuring durability.
- Compatibility with common OEM sensors as well as customer sensor calibration input.
- Ignition Plug and Play compatibility with GM 24x and 58x LSx engines, GM HEI, Ford TFI, magnetic and hall effect trigger, and other ignition systems. Ongoing development for new Plug and Play applications with custom settings configurable for various applications.
- 1-5 Bar MAP sensor capability for accurate monitoring.
- Two-channel knock control sensor inputs for both one or two-wire knock sensors.
- Dedicated fuel and oil pressure inputs.
- Control of both stepper and PWM Idle Air Control (IAC) motors.
- Support for speed density, Alpha-N, or combination fueling strategies.
- 4 Programmable high or low Pulse Width Modulated (PWM) outputs and 4 fully configurable inputs for versatile use.
- 4 Stage nitrous oxide control, fully featured to eliminate the need for a separate nitrous controller device.
- Configurable as "Wet" or "Dry" with closed-loop feedback.
- Progressive control based on time, RPM, or boost, requiring 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 using Holley Water/Meth solenoids designed and calibrated for precise tuning, allowing the user to enter Water/Meth flow as a percentage of fuel injector flow for unmatched Water/Meth tuning precision in the industry.
