Edelbrock Pro-Flo 4 EFI Upgrade Kit (from Legacy Pro-Flo to Pro-Flo 4)

This Pro-Flo 4 EFI kit provides a solution for consumers who own a legacy Pro-Flo EFI System and want to upgrade to Pro-Flo 4.

The Legacy Pro-Flo to Pro-Flo 4 EFI Upgrade Kit includes a harness, supporting sensors, and components for converting from a Legacy Pro-Flo EFI System to Pro-Flo 4 EFI. This kit consists of supporting sensors, ECU, wide-band O2 sensor, wiring harness, IAC valve, and IAC adapter. This EFI system has both fuel and spark control features.

The ECU includes a learning capability feature that adjusts the fuel injection calibration to maintain the specified target air-fuel ratio. Minimal setup and tuning adjustments are required with Edelbrock ’s E-Tuner Software for IOS and Android tablets and cell phones. The software includes base calibrations for most applications and necessary adjustments for AFR target, ignition curve, idle speed, acceleration tuning, coolant fans, rev limiter, etc.

The customer must provide an induction system, including the manifold, throttle body, fuel rails, and injectors, as well as a Pro-Flo distributor, fuel pump, regulator, and fuel lines. Users must refer to the Calibration Matrix in the instructions for the required injector size, depending on engine cubic inches and HP requirements. Required inj ector sizes 29 lb./hr., 35 lb./hr., 42 lb./hr., and 60 lb./hr. Compatibility with forced induction applications requires 80 lb./hr. injectors.
