E-Tuner 4 is Edelbrock's cutting-edge Android app designed specifically for the Pro-Flo 4 EFI System. This app revolutionizes how you manage and fine-tune your vehicle's engine performance directly from your Android device.

With E-Tuner 4, you can effortlessly communicate with your PF4 ECU through Bluetooth, allowing you to adjust various ECU settings such as air-fuel ratios, ignition timing, idle speed, acceleration fuel, and cold start mixture. Additionally, you can monitor engine and sensor data in real-time, providing you with a comprehensive view of your vehicle's performance wirelessly.

The E-Tuner 4 Setup Wizard streamlines the setup process for your Pro-Flo 4 EFI system. By simply entering your engine displacement (CID), camshaft, and kit specifications, the wizard guides you to select the perfect base calibration tailored to your specific application, ensuring you're ready to hit the road with minimal fuss.

E-Tuner 4 provides a robust base calibration, allowing you to operate your vehicle smoothly without immediate adjustments. However, for those looking to fine-tune their setup, the app's "Advanced Tuning" functions offer a range of options to optimize your calibration. Whether you aim to improve fuel efficiency during cruising or boost performance with advanced timing, these features cater to your needs. Additionally, a diagnostic page is available for troubleshooting, ensuring you can address any issues efficiently.

Once your setup is complete, dive into E-Tuner 4's vibrant gauge displays to keep an eye on your engine's performance. Unlike other tuning solutions, E-Tuner 4 transforms your Android device into a dynamic mini-dashboard, providing real-time insights into your vehicle's operation.

Curious about how E-Tuner 4 works? You can explore its features without an Edelbrock EFI System by activating "Demo Mode." This mode lets you navigate through the Setup Wizard, Advanced Tuning, and Gauge Displays, giving you a firsthand experience of the app's capabilities.
