E-Tuner 4

E-Tuner 4 is the exclusive Android application from Edelbrock, designed specifically for the Pro-Flo 4 EFI system.

E-Tuner 4 is Edelbrock's newest dedicated Android app, built for the Pro-Flo 4 EFI system.

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

The E-Tuner 4 Setup Wizard simplifies your Pro-Flo 4 EFI configuration by guiding you through the selection of the correct base calibration for your specific engine setup. Simply input your engine displacement (CID), camshaft type, and kit specifications, and you're ready to start.

E-Tuner 4 applies a reliable base calibration that allows your vehicle to run smoothly without requiring immediate tuning adjustments. If you wish to personalize performance, the app also includes an Advanced Tuning section with tools to fine-tune your calibration—ideal for improving fuel economy during cruising or advancing ignition timing for more power. A diagnostics page is also available to assist with troubleshooting.

Once your system is running, explore E-Tuner 4’s dynamic gauge displays to track engine performance in real-time. Unlike traditional tuning handhelds, your phone or tablet can serve as a compact dashboard even after tuning is complete.

You can also explore E-Tuner 4 without an active Edelbrock EFI system by enabling "Demo Mode." This lets you navigate key features—such as the Setup Wizard, Advanced Tuning, and Gauge Displays—to familiarize yourself with the app’s functionality.

*** Warning! ***

E-Tuner 4 is compatible only with the Edelbrock Pro-Flo 4 EFI system. It is not supported on V1 E-Street, V2 E-Street, Pro-Flo 3, or other legacy Edelbrock EFI systems. If you own one of these earlier systems, please visit http://www.edelbrock.com/automotive/mc/efi/support.shtml to download the appropriate Android app files.
