The Edelbrock Pro-Flo 4 XT EFI Kit #35813 for 1986-earlier Small-Block Chevrolet engines is a complete bolt-on electronic fuel injection system featuring a black powder-coated XT intake manifold with large plenum and long tapered runners that comes ready to run with high-flow injectors, fuel rails and 90mm throttle body preassembled for you at the Edelbrock factory. This kit is rated at a maximum 625 horsepower with 35 lb/hr injectors and includes all supporting sensors, a wide-band O2 sensor, wire harnesses and Android-based tablet. Also included is a single-connection distributor designed to work specifically with Pro-Flo 4 providing fully sequential port injection and infinite control over ignition and fuel events under all conditions. Key Pro-Flo 4 advancements are its Self-Calibrating Fuel Map Technology, Wide-Band O2 Closed Loop Mixture Control, and new low-profile ECU with faster processor and upgraded Bluetooth chip for reliable connectivity with the E-Tuner app that comes preinstalled on the tablet. The E-Tuner includes a Setup Wizard to guide you through setup and provides fuel and spark adjustability for complete control over the system. Pro-Flo 4 EFI #35813 for the Small-Block Chevy requires no laptop tuning. Minimal setup and tuning adjustments are required with base calibrations provided in the software. The ECU is self-learning and will continually adjust the fuel injection calibration for maximum performance by maintaining a specified target air-fuel ratio as you drive. The E-Tuner provides the ability to fine-tune air-fuel ratios, ignition curve, idle speed, acceleration fuel, fans, rev-limiter and more. Multiple displays let you monitor engine performance in real-time from inside or outside of the vehicle while retaining the simplicity that Pro-Flo 4 systems are known for.
