E-Tuner 4 is Edelbrock's dedicated Android app designed exclusively for the Pro-Flo 4 EFI System.

E-Tuner 4 represents Edelbrock’s newest Android app crafted specifically for the Pro-Flo 4 EFI System.

E-Tuner 4 establishes Bluetooth connectivity with your PF4 ECU, enabling wireless management and real-time tuning of critical ECU parameters like air-fuel ratios, ignition timing, idle speed, acceleration fuel, and cold start mixture while monitoring engine and sensor data directly from your Android device.

The E-Tuner 4 Setup Wizard streamlines Pro-Flo 4 EFI configuration by guiding you through selecting the optimal base calibration tailored to your engine. Simply input details like displacement (CID), camshaft specifications, and kit details—you'll be ready in no time!

E-Tuner 4 delivers a reliable base calibration for immediate vehicle operation, while its Advanced Tuning options let you fine-tune performance precisely. Adjust parameters for leaner cruising to boost mileage or advance timing for enhanced power. A dedicated diagnostics page also aids troubleshooting.

Once configured, utilize E-Tuner 4’s dynamic gauge displays as a real-time performance monitor. Transform your phone or tablet into a functional dashboard post-tuning—a feature unique to this solution.

Explore E-Tuner 4’s interface without an active EFI connection through Demo Mode. Experience core functionalities like the Setup Wizard, Advanced Tuning panel, and gauge displays to familiarize yourself with the app's capabilities.
