Pro-Flo 4 Dual-Quad HEMI EFI System #35670 is intended for use with1964-71 Mopar Gen II 426-572 HEMI engines operating in the 2,500-6,500+ RPM range. This EFI incorporates a single-plane Air-Gap design manifold with dual square-bore 4150-style throttle bodies that bolts directly onto vehicles with a shaker hood. The Dual-Quad HEMI EFI manifold is compatible with factory-style cylinder heads but optimized for use with Victor Jr. HEMI heads. Manifold comes preassembled and ready to run with throttle bodies, 60 lb/hr injectors and fuel rails. 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. This system is rated for 825 horsepower at 43 PSI with all supporting sensors, ECU, wire harnesses and 7-inch Android tablet included for a streamlined installation. Key advancements of Pro-Flo 4 EFI 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 does not require 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 to get the maximum performance out of your engine 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.
