Looking for a plug and
play alternative for your stock or built late model factory 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.
HP EFI ECU & Harness Kit, GM LS1
Installation Notes
Holley HP EFI systems are equipped with 4
programmable inputs and 4 programmable outputs that are ideal for most
vehicles with a single power adder. This feature allows the user to
configure the system to support a wide range of controls including boost
control, progressive nitrous, water/meth injection, speed inputs, fuel
pump control, AC inputs, timing retard inputs and various other uses.
When selecting an ECU, users need to ensure their planned controls can
be run with the 4 inputs and 4 outputs as certain combinations may use
more I/Os than are available. If more I/Os are required, users should
choose the Dominator VMS.
Features
- 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
- 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
- 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
- Plug and Play control of factory GM 24x and 58x LSx engines
-
Integrated single channel wide band oxygen sensor control. Works with
NTK or Bosch sensors. More channels can be added via CAN bus
- Internal data-logging standard with a huge 2GB of memory
- 4 Stage progressive nitrous control
- Turbo boost control
- Integrated water/methanol injection control
- Self-tuning fuel table strategy greatly simplifies tuning process
- Individual cylinder fuel and spark control allows you to unlock your engine’s potential
- Works with 4, 6, 8 cylinder engines
- 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
- Allows for use of common OEM sensors as well as customer sensor calibration input
-
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
- 1-5 Bar MAP sensor capability
- 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
- 4 Programmable high or low Pulse Width Modulated (PWM) outputs and 4 fully configurable inputs can be configured for use
- 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
