E-Tuner 4

E-Tuner 4 is Edelbrock's exclusive Android app for managing the Pro-Flo 4 EFI system.

E-Tuner 4 is the latest Android app from Edelbrock, designed exclusively for the Pro-Flo 4 EFI System.

It wirelessly connects to your PF4 ECU via Bluetooth, allowing you to manage and live-tune settings like air-fuel ratios, ignition timing, idle speed, acceleration fuel, and cold start mixture while monitoring real-time engine and sensor data from your Android device.

The E-Tuner 4 Setup Wizard simplifies your Pro-Flo 4 EFI installation by helping you select the right base calibration for your application. Simply input your engine's displacement (CID), camshaft specifications, and kit details to get started.

E-Tuner 4 applies a robust base calibration so your vehicle can run immediately without tuning adjustments. Should you wish to optimize further, the app's "Advanced Tuning" features let you fine-tune your calibration to achieve your desired performance—whether you want leaner cruising for better mileage or advanced timing for more power. A diagnostic page is also available for troubleshooting.

Once your vehicle is running, explore E-Tuner 4's vivid gauge displays to keep an eye on engine performance. Unlike dedicated tuning handhelds, you can use your phone or tablet as a compact dashboard even after tuning is complete.

You can also explore E-Tuner 4 without connecting to an Edelbrock EFI system by enabling "Demo Mode." This lets you access key features like the Setup Wizard, Advanced Tuning, and Gauge Displays to understand how the app works.

*** Warning! ***

E-Tuner 4 is only 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. If you own one of these systems, please visit http://www.edelbrock.com/automotive/mc/efi/support.shtml to download the appropriate Android app.

The E-Tuner 4 app currently supports most devices running Android 6.0 or later and is optimized for 5 to 7-inch Android phones and tablets. Please check back for future updates.
