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 Hemi engine, implementing drive-by-wire throttle and variable camshaft timing (VCT) that is calibrated for best performance in hot rod engine swap applications. This system also supports variable cam control on all Eagle engines. Pro-Flo 4+ kit #36140 includes an ECU with base calibration; OEM-style wiring harnesses; MAP, O2 and IAT sensors. 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. Pro-Flo 4+ for the 2008-2012 Gen III Hemi uses a speed-density fueling strategy with an included MAP and IAT sensor.
