LS ECU & Harness Kits

The new Pro-Flo 4 LS ECU & Harness Kit is what you'll need to complete your Gen III or Gen IV Chevy LS engine swap. Retains the LS engine's OEM EFI components.

Now you can get an affordable easy solution for adding EFI on your Gen III or IV LS engine. This basic EFI conversion kit is a great option if you already have an EFI intake on your LS engine and only require an engine management system. This kit is a great solution for any performance level LS engine swap. These kits include the all new Pro-Flo 4 ECU, Bosch 4.9 LSU wide band sensor and harness. The harnesses connect directly to the factory coils, injectors, camshaft/crank sensors and other sensors on the factory LS intake manifold. To further simplify your LS EFI conversion experience, this system also uses the exclusive Edelbrock E-Tuner 2 wireless Bluetooth Android based tuning application that can be downloaded to your smartphone or optional tablet. No complicated laptop software necessary, as Edelbrock has done the hard work for you. The E-Tuner 2 app includes a setup wizard that’s easy to use and the ECU is pre-loaded with calibrations that best fit your engine setup. Once your vehicle is up and running, the self-learning features of the E-Tuner 2 app continually adjust the fuel mapping to get the best performance available from your engine package, leaving you to enjoy the ride!
