What is the primary benefit of upgrading to this FAST EZ-EFI system?

The main advantage is converting your carbureted engine to electronic fuel injection (EFI). This typically results in improved starting, smoother idle, better throttle response, and more consistent performance across varying conditions, all while the system tunes itself as you drive.

What is included in the FAST EZ-EFI Self Tuning Fuel Injection System kit?

The kit includes the self-tuning throttle body with integrated fuel rails, a color touchscreen hand-held unit for setup and monitoring, an updated wiring harness with fuses, and all necessary OEM-style sensors. It's designed to bolt onto your existing 4150-style carburetor manifold.

Can I use this system with my existing ignition setup?

Yes, the FAST EZ-EFI system is designed to work with all ignition setups, including traditional HEI (High Energy Ignition) systems. This means you likely won't need to change your current ignition components to make the EFI system function.

Product Details

This is the FAST EZ-EFI Self Tuning Fuel Injection System, a complete kit designed to bring your carbureted or multi-port engine up to 650 horsepower into the modern age of fuel injection. It's built to bolt directly onto any manifold designed for a 4150-style carburetor, meaning you won't need to swap your intake. This system is a popular choice for street rods and muscle cars looking for improved drivability and performance without a complex installation. It works with a wide range of vehicles, including many classic Chevrolet, Buick, and even some Bentley models from the 80s and 90s.

What makes this system stand out is its self-tuning capability. Once installed, you'll use the included color touchscreen hand-held unit to answer a few setup questions. From there, the system tunes itself as you drive, adjusting fuel delivery based on real-world conditions. The updated ECU hardware offers better protection against electrical noise, and the wiring harness is now more streamlined with added fuses. The throttle body itself is a die-cast, black powder-coated unit with integrated fuel rails, designed for better fuel distribution and airflow. It even retains your original carb-style throttle linkage and uses standard GM sensors, which are readily available at any auto parts store. Installation is straightforward enough that many people can complete it in an afternoon.

The hand-held unit isn't just for setup; it also offers various display screens and an LED indicator that can alert you to issues like overheating or function as a shift light. This system is compatible with all ignition setups, including HEI. For those needing more power, FAST also offers upgrade kits for higher horsepower applications.
