550-606 Holley EFI HP Universal FORD V8 Multi-Point Fuel Injection, Includes Bosch Oxygen Sensor, and Ford V8 Injector

Basic universal HP EFI system for Naturally Aspirated small block Fords.  Includes Bosch wideband sensor.  Not for TFI specific ignition.  Will require additional ignition input wire harness depending on application.

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.
