Edelbrock 35970 Pro-Flo 4 EFI System Pontiac 326-455

The Edelbrock Pro-Flo 4 EFI System is a complete electronic fuel injection conversion kit specifically designed for Pontiac 326-455 cubic inch engines. This comprehensive system delivers modern fuel injection performance while maintaining a traditional appearance with its 4150-style satin finish single plane intake manifold.

Complete System Includes:

• Traditional 4150-style satin finish single plane intake manifold
• Four 29 lb/hr fuel injectors capable of supporting up to 450 HP at 58 PSI fuel pressure
• All-new compact ECU with faster processor and waterproof design—half the depth of previous generation
• Plug-and-play single connection distributor engineered specifically for Pro-Flo 4
• Fully terminated, made-in-USA wiring harness with clearly labeled connections
• Upgraded Bluetooth chip for faster, more reliable connection that won't drop signal

E-Tuner 4 App Features:

The system is controlled through Edelbrock's exclusive E-Tuner 4 Android app, available free from the Google Play Store. The app features dyno-developed base calibrations and communicates wirelessly via Bluetooth with the ECU's self-learning capability to continually optimize performance. A simple setup wizard guides you through initial configuration, and multiple dash displays allow real-time monitoring of engine vitals. No laptop tuning required.

Advanced Tuning Control:

While maintaining Pro-Flo's signature ease of use, the system gives advanced tuners full control over air-fuel ratios, ignition timing curves, idle speed, acceleration enrichment, cooling fan operation, and rev limiter settings. The ECU's self-learning algorithm continuously refines the calibration for maximum performance.

Compatible with Android smartphones and tablets. Complete kits with pre-installed 7-inch Android tablet are also available separately.
