Edelbrock's E-Tuner 4 is the exclusive Android app designed for seamless control and tuning of the Pro-Flo 4 EFI System. This cutting-edge app provides wireless, real-time management of your engine's performance directly from your Android device via Bluetooth communication with the PF4 ECU.

Effortlessly manage key ECU settings, including air-fuel ratios, ignition timing, idle speed, acceleration fuel enrichment, and cold start mixture. Simultaneously monitor vital engine and sensor data for comprehensive performance oversight. The intuitive Setup Wizard simplifies the initial configuration process, guiding you through the selection of the optimal base calibration based on your engine's displacement (CID), camshaft, and kit specifications. A pre-configured base calibration allows immediate vehicle operation without requiring any initial tuning adjustments.

For those seeking advanced customization, E-Tuner 4 offers a robust "Advanced Tuning" section. Fine-tune your calibration to achieve precise performance goals, whether it's optimizing fuel efficiency by running leaner during cruising or maximizing power output through 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 monitor with its vivid gauge displays. Visualize your engine's performance data in real-time, providing a comprehensive mini-dashboard experience. Even without a connected Edelbrock EFI System, explore E-Tuner 4's core functionalities through "Demo Mode," allowing interaction with the Setup Wizard, Advanced Tuning, and Gauge Displays.

***Warning!*** E-Tuner 4 is exclusively compatible with the Edelbrock Pro-Flo 4 EFI System. It is *not* compatible with V1 E-Street, V2 E-Street, Pro-Flo 3 EFI systems, or other Edelbrock legacy EFI systems.
