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

E-Tuner 4 is the latest Android app from Edelbrock, developed specifically for the Pro-Flo 4 EFI system.

Using Bluetooth connectivity, E-Tuner 4 communicates with your PF4 ECU, allowing you to manage and tune various settings like air-fuel ratios, ignition timing, idle speed, acceleration fuel, and cold start mixture. You can also monitor engine and sensor data in real time directly from your Android device.

The E-Tuner 4 Setup Wizard makes it easy to configure your Pro-Flo 4 EFI system by guiding you through the process of selecting the correct base calibration for your application. Simply input your engine's displacement (CID), camshaft type, and kit specifications to get started quickly.

E-Tuner 4 applies a reliable base calibration so your vehicle can run smoothly without any immediate adjustments. If you wish to fine-tune performance, the app provides advanced tuning functions to help you refine the calibration and optimize your vehicle's performance. Whether you want to improve fuel economy by running leaner during cruising or increase performance by adjusting timing, the Advanced Tuning section offers the necessary tools. A diagnostic page is also available for troubleshooting.

Once your setup is complete, explore E-Tuner 4's vibrant gauge displays to keep track of engine performance. Unlike traditional handheld tuners, you can repurpose your phone or tablet as a mini-dashboard after tuning.

You can try E-Tuner 4 even without an Edelbrock EFI system by enabling "Demo Mode." This allows you to explore key features like the Setup Wizard, Advanced Tuning, and Gauge Displays, giving you a feel for how the app works.
