Pro-Flo 4 EFI ECU and Electronics Kit for Small Block/Big Block Chevrolet

These new Pro-Flo 4 ECU and Electronics Kits for small or big-block Chevrolet engines offer an economical, plug-and-play solution for enthusiasts who want to keep their existing EFI Induction system (intake manifold, fuel rails, and accessories) but want the performance advantages of the Pro-Flo 4 EFI system. Previously, the only option was to buy an entire Pro-Flo 4 EFI system, leaving unneeded or duplicate parts.

Pro-Flo 4 EFI ECU and Electronics kits include supporting sensors, a distributor, an ECU, a wide-band O2 sensor, a wiring harness, and components for Chevrolet SB and BB applications. 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 a manifold, throttle body, fuel rails, and injectors. Also, a fuel pump, regulator, or fuel lines are not included. Users must refer to the Calibration Matrix in the instructions for the required injector size depending on engine cubic inches and HP requirements. Required injector sizes 29 lb./hr., 35 lb./hr., 42 lb./hr., and 60 lb./hr. Compatibility with forced induction applications requires 80 lb./hr. injectors.
