Holley HP EFI Multi Port BBC 4BBL Fuel Injection System - 1000 CFM Standard Deck Rectangular Ports

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/methanol 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. MPFI Systems do not include injectors or a fuel pump. They need to be sized for the application and can be purchased seperately from Holley.

The following sensors are included: TPS - IAC - MAP - CTS - MAT - Wideband O2

ECU is certified to ISO 8846, SAE J1171 & United States Coast Guard Requirements for Ignition Protection & Fire Resistance.
