Looking for a plug and play kit for your GM LS engine? The HP ECU allows you to accurately control the fuel and ignition of your engine plus much more! Got a stock LS engine? Simply download a base map and you're on your way. Got a turbocharged, nitrous fed LS engine on water/meth? This HP EFI kit can control that too! Stop re-flashing your factory ECU every time you make a performance modification.
Features:
- Eight sequentially driven 8:2 peak and hold injector drivers capable of driving up to 16 low or high-impedance injectors are standard.
- 8-channel distributorless ignition (DIS) outputs capable of directly driving "smart" ignition coils or Holley DIS coils.
- Integrated, single-channel wideband oxygen sensor control. Works with NTK or Bosch sensors. More channels can be added via CAN bus.
- Internal data-logging is 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 allow you to unlock your engine's potential.
- Compatible with 4, 6, and 8-cylinder engines.
- Unique lbs./hr.-based fueling strategy greatly simplifies tuning.
- Advanced idle, closed loop, and enrichment strategies allow for very stable operation.
- 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.
- 1-5 bar MAP sensor capability.
- 2-channel knock control sensor inputs for both one and 2-wire knock sensors.
- Dedicated fuel and oil pressure inputs.
- Control both stepper and PWM idle air control (IAC) motors.
- Speed density, Alpha-N, or combination fueling strategies.
- Four programmable high or low pulse width modulated (PWM) outputs and four fully configurable inputs can be configured for use.
- Lean or rich safety cutoff.
Kit includes ECU, harness, communication cable, software and and Bosch wideband 02 sensor designed to be used with GM LS1/LS6 engines with factory GM coils and a 24 tooth crank sensor.
Note: 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 or add a Holley EFI Input/Output module.
Designed to be used with GM LS1/LS6 engines with factory GM coils and a 24 tooth crank sensor.
