Edelbrock Pro-Flo 4+ kit #36130 is an EFI engine management system that simplifies the installation of a modern factory Chevy Gen III/IV LS engine with EFI and drive-by-wire (DBW) into a non-EFI muscle car, truck or hot rod. Pro-Flo 4+ allows you to leave the factory ECU and wiring harnesses at the junkyard by providing a plug-and-play control system that is specially designed for the Gen III/IV LS engine, implementing DBW throttle that is calibrated for best performance in hot rod engine swap applications and is fully compatible with all factory actuators. This system also supports dual DBW throttle bodies for use with the Cross-Ram LS3 intake manifold. Pro-Flo 4+ kit #36130 includes an ECU with base calibration; OEM-style wiring harnesses; MAP, O2, and fuel pressure sensors; and a Bluetooth tablet for wireless programming, diagnostics, performance monitoring and calibration adjustments. Note that some supporting wiring harnesses for drive-by-wire and alternator configuration are necessary determined by the reluctor wheel (either 24x or 58x). LS applications implement a speed density fueling strategy using an OEM MAP sensor which eliminates the factory MAF sensor, inlet air piping and air box. This allows unlimited options in your air intake design. The Pro-Flo 4+ ECU provides mounting versatility with a compact weather-resistant housing and features a unique self-learning capability that adjusts the fuel map as you drive, providing optimum performance with no need for laptop tuning or costly dyno sessions. Setup is quick and easy thanks to Edelbrock’s E-Tuner 4 software for Android tablets and smartphones. A non-adjustable Alternator Control is set to regulate at 14.5 volts and only OEM alternators are supported. Minimal tuning adjustments are required when the provided base calibration is used, giving you great performance right out of the box. Pro-Flo 4+ is covered by a 2-year warranty and is backed by the industry’s most extensive technical support team.
