{"product_id":"edelbrock-small-block-big-block-chevrolet-pro-flo-4-efi-ecu-electronics-kit","title":"Edelbrock Small Block\/Big Block Chevrolet Pro-Flo 4 EFI ECU \u0026 Electronics Kit","description":"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.\n\nPro 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.\n\nThe 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.\nThe Pro-Flo 4 ECU \u0026amp; Electronics Kit for Chevy SB and BB allows customers with existing EFI induction systems to upgrade to the PF4 EFI. Includes sensors, ECU, harness, and other components to be controlled with iOS\/Android E-Tuner software.\nIncludes Pro Flo 4 Distributor for SB and BB Chevrolet's.\nRequires EFI Manifold, Fuel Injectors, Fuel Rails, Throttle Body and 1 Bar Map Sensor\nRequires 29,35, 42, or 60 LbHr Injectors. 80LbHr Injectors and 2 Bar Map sensor for forced Induction applications\n\u003cul\u003e\n  \u003cli\u003eEconomical EFI System solution for Chevrolet SB and BB Engines with existing EFI Manifold Assembly\u003c\/li\u003e\n  \u003cli\u003eSimplified installation, providing all existing features of Pro Flo 4 EFI\u003c\/li\u003e\n  \u003cli\u003eAlternative for complete Pro Flo 4 EFI System\u003c\/li\u003e\n\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbdoy\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Y\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbdoy\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":47681311801497,"sku":"ede35716","price":1364.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/2611\/3689\/files\/5d6033c7ae365fe02a47f383ed0518eeL.jpg?v=1779349753","url":"https:\/\/msvracingpowersports.com\/products\/edelbrock-small-block-big-block-chevrolet-pro-flo-4-efi-ecu-electronics-kit","provider":"MSV Racing","version":"1.0","type":"link"}
