Application Description

E-Tuner 4 is Edelbrock's dedicated Android application designed for the Pro-Flo 4 EFI System.

E-Tuner 4 represents the newest exclusive Android app from Edelbrock for the Pro-Flo 4 EFI System.

E-Tuner 4 connects wirelessly via Bluetooth to your PF4 ECU, allowing you to manage and live-tune various ECU parameters—including air-fuel ratios, ignition timing, idle speed, acceleration fuel, and cold start mixture—while monitoring engine and sensor data in real time from your Android device.

The E-Tuner 4 Setup Wizard streamlines your Pro-Flo 4 EFI installation by helping you choose the right base calibration for your engine setup. Simply enter your engine’s displacement (CID), camshaft type, and kit specifications, and you're ready to go.

E-Tuner 4 applies a reliable base calibration so your vehicle can run smoothly without immediate tuning adjustments. For those who want to fine-tune, the app includes an "Advanced Tuning" section to help you perfect your calibration and achieve your desired performance. Whether you're aiming for better fuel economy by running leaner during cruising or advancing timing for increased power, the Advanced Tuning tools are available. A diagnostic page is also included for troubleshooting.

Once your system is active, explore E-Tuner 4’s dynamic gauge displays to track engine performance. Unlike traditional handheld tuners, you can use your phone or tablet as a mini dashboard even after tuning is complete.

You can also try E-Tuner 4 in "Demo Mode" without connecting to an Edelbrock EFI system. This mode lets you explore key features like the Setup Wizard, Advanced Tuning, and Gauge Displays to familiarize yourself with the app’s functionality.

*** Warning! ***

E-Tuner 4 is exclusively compatible with the Edelbrock Pro-Flo 4 EFI System. It is NOT compatible with V1 E-Street, V2 E-Street, Pro-Flo 3, or other legacy Edelbrock EFI systems.
