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

E-Tuner 4 represents Edelbrock's latest exclusive Android app, designed specifically for the Pro-Flo 4 EFI System.

E-Tuner 4 wirelessly connects to your PF4 ECU via Bluetooth, enabling you to manage and live-tune numerous ECU parameters like air/fuel ratios, ignition timing, idle speed, acceleration enrichment, and cold start mixture, while also monitoring real-time engine and sensor data directly from your Android device.

The E-Tuner 4 Setup Wizard streamlines your Pro-Flo 4 EFI configuration by guiding you to select the correct base calibration for your specific engine setup. Simply input your engine's displacement (CID), camshaft profile, and kit details, and you're ready to start.

E-Tuner 4 applies a robust base calibration, allowing the vehicle to run perfectly without any immediate tuning changes. Should you wish to make adjustments, the app provides a suite of "Advanced Tuning" functions to fine-tune your calibration and precisely dial in the vehicle's performance. Whether you want to lean out cruise mixtures for better fuel economy or advance timing for more power, the Advanced Tuning section has you covered. A dedicated diagnostic page is also included for troubleshooting.

Once your system is running, explore E-Tuner 4's dynamic gauge displays to track your engine's performance. Unlike traditional handheld tuners, you can continue using your phone or tablet as a compact dashboard even after tuning is complete.

You can also explore E-Tuner 4's interface without being connected to an Edelbrock EFI system by activating "Demo Mode." This feature lets you access the app's core functions, interact with pages like the Setup Wizard, Advanced Tuning, and Gauge Displays, and familiarize yourself with how E-Tuner 4 operates.

*** Warning! ***

E-Tuner 4 is compatible exclusively with the Edelbrock Pro-Flo 4 EFI System. It is NOT compatible with V1 E-Street, V2 E-Street, Pro-Flo 3, or any other legacy Edelbrock EFI systems. If you own one of the aforementioned systems, please visit http://www.edelbrock.com/automotive/mc/efi/support.shtml to download the appropriate Android application files.
