Edelbrock Pro-Flo 4 GM LS ECU & Engine Harness Kits

Self Tuning Controller for Popular Engine Swaps

Take control of an LS engine with Edelbrock Pro-Flo 4 ECU and Harness! Developed to simplify a modern engine swap, these kits will work with factory EFI systems by integrating with the existing injectors, coils, sensors, and intake manifold.

Featuring a waterproof ECU, Pro-Flo 4 utilizes Bluetooth connectivity with an exclusive free to download E-Tuner app for Android-based devices. Edelbrock's E-Tuner app contains dyno developed base setting calibration and self-learning technology, eliminating the need for a dyno tune or laptop tuning. This app will give you total control of the Pro-Flo 4 system; with the ability to adjust air-fuel ratios, ignition curve, idle speed, acceleration fuel, coolant fans, rev limiter, and multiple dash displays for monitoring engine vitals while you drive. If you don't have a compatible device, Edelbrock offers EFI kits that are available with a 7 in. Android tablet that includes the E-Tuner app preinstalled.
