E-Tuner 4 is Edelbrock's cutting-edge Android app designed exclusively for the Pro-Flo 4 EFI System, offering a seamless tuning experience for your vehicle. With E-Tuner 4, you can connect to your PF4 ECU via Bluetooth, allowing you to effortlessly manage and live-tune critical ECU settings such as air-fuel ratios, ignition timing, idle speed, acceleration fuel, and cold start mixture. Additionally, you can monitor your engine and sensor data in real-time, all from the convenience of your Android device.

The E-Tuner 4 Setup Wizard streamlines your Pro-Flo 4 EFI setup process by guiding you through selecting the ideal base calibration for your specific engine. Simply provide details like engine displacement (CID), camshaft, and kit specifications, and you’re all set to go! E-Tuner 4's base calibration is robust enough to run your vehicle smoothly without any immediate adjustments. However, if you're looking to fine-tune your engine, E-Tuner 4's "Advanced Tuning" functions are at your disposal, allowing you to adjust settings for better mileage or enhanced performance. The app also features a diagnostic page to help with troubleshooting.

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 devices, your Android phone or tablet can serve as a mini-dashboard, providing real-time insights into your engine's operations.

For those curious about E-Tuner 4 but not yet connected to an Edelbrock EFI System, "Demo Mode" is available. This feature lets you explore the app's main functionalities, including the Setup Wizard, Advanced Tuning, and Gauge Displays, giving you a comprehensive understanding of how E-Tuner 4 works.

Important Note:

E-Tuner 4 is strictly compatible with the Edelbrock Pro-Flo 4 EFI System and does not support V1 E-Street, V2 E-Street, Pro-Flo 3 EFI, or other Edelbrock Legacy EFI Systems. If you own one of these systems, visit http://www.edelbrock.com/automotive/mc/efi/support.shtml to download the appropriate Android app.
