Edelbrock's E-Tuner 4 is the exclusive Android app designed for seamless control of your Pro-Flo 4 EFI System. This cutting-edge application provides wireless, real-time management and tuning capabilities via Bluetooth connectivity to your PF4 ECU.

E-Tuner 4 empowers you to fine-tune a wide array of ECU settings, including air-fuel ratios, ignition timing, idle speed, acceleration fuel enrichment, and cold start mixture. Simultaneously, monitor crucial engine and sensor data directly from your Android device, creating a mobile performance monitoring center.

The intuitive Setup Wizard simplifies the Pro-Flo 4 EFI setup process. Simply input your engine displacement (CID), camshaft, and kit specifications, and E-Tuner 4 will automatically apply a robust base calibration, allowing immediate vehicle operation. No complex tuning adjustments are needed to get started.

For those seeking advanced customization, E-Tuner 4 offers comprehensive "Advanced Tuning" options. Refine your calibration to optimize performance, whether you're aiming for improved fuel economy through leaner cruising mixtures or enhanced power via advanced timing adjustments. A dedicated diagnostic page facilitates efficient troubleshooting.

Beyond tuning, E-Tuner 4 transforms your Android phone or tablet into a dynamic performance gauge display. Monitor your engine's vital statistics with vivid, customizable gauges, effectively turning your device into a mini-dashboard.

Explore E-Tuner 4's features even without a connected Edelbrock EFI System using "Demo Mode." This allows you to navigate the Setup Wizard, Advanced Tuning options, and Gauge Displays, providing a comprehensive preview of the app's functionality.
