*E-Tuner 4 App: A key component to the Pro-Flo 4 EFI System is the E-Tuner 4 app. This app features dyno developed base calibration which makes each system ready-to-run right out of the box. The E-Tuner 4 app uses a Bluetooth wireless connection to communicate with the ECU's self-learning capability to continually adjust the calibration to get maximum performance and multiple dash-displays that monitor engine vitals. The E-Tuner 4 app is free and can be downloaded from the Google Play Store, allowing the use of most personal Android-based smartphones or tablets.

Sequential-Port EFI for your Classic!
Pro-Flo 4 EFI Systems from Edelbrock is the latest fully sequential port self-learning electronic fuel injection generation. Pro-Flo 4 EFI systems are a step up from entry-level throttle body EFI systems and are intended for V8 engines initially equipped with carburetors. Each system features an all-new ECU with a faster processor and waterproof design, tuning control of air-fuel ratios, ignition curve, idle speed, acceleration fuel, coolant fans, and rev limiter. Edelbrock Pro-Flo 4 EFI systems retain the simplicity that Pro-Flo systems are known for but deliver more accurate, and precise performance output, all without laptop tuning.
Edelbrock Pro-Flo 4 EFI systems redefine the performance upgrade, offering unmatched control, fuel efficiency, and drivability. This all-in-one fuel injection solution replaces outdated carb setups with modern multi-port EFI technology, delivering smoother cold starts, better throttle response, and noticeable fuel economy gains.
At the core of each system is a high-performance Edelbrock intake manifold with a 1,000 CFM throttle body, individual fuel rails, and injectors for each cylinder—optimizing atomization, eliminating fuel puddling in the plenum, and ensuring even mixture distribution. This sequential design improves performance across the rev range and avoids the imbalance typical of throttle-body versions.
What sets the system apart is the included E-Tuner 4 app, offering advanced tuning directly from your smartphone or tablet. This intuitive tool supports ignition curve adjustments, idle control, acceleration enrichment, and more—all without the complexity of laptop tuning. The system also carries a worry-free 2-year warranty straight from Edelbrock.
Advantages at a Glance:
- Hassle-free cold starts and smooth performance from idle to wide-open throttle
- Improved fuel mileage compared to carburetor-based setups
- Precise, cylinder-by-cylinder fuel control for optimized combustion
- App-based tuning with self-learning capability and drag-and-drop simplicity
- Backed by a two-year manufacturer warranty
For those looking to upgrade, the edelbrock proflo 4 system balances powerful control with everyday convenience. It represents the future of electronic fuel management, outperforming traditional carburetion on every front.
