What is wide-band closed-loop fuel control?

Wide-band closed-loop fuel control means the system uses a wide-band oxygen sensor to precisely measure the air-fuel ratio in your exhaust. The ECU then continuously adjusts fuel delivery to maintain the optimal ratio, improving efficiency and performance.

Does this programmer come with everything needed for installation?

This product is the ECU programmer itself. While it simplifies EFI conversion, you may need additional components such as a throttle body, fuel pump, fuel injectors, and wiring harness depending on your specific engine and existing setup. Refer to the manufacturer's installation guide for a complete list.

Can this ECU be used with my existing ignition system?

The EZ-EFI 1.0 ECU is designed to manage fuel delivery and can also control ignition timing when used with a compatible ignition system. Consult the manufacturer's documentation to ensure compatibility with your specific ignition setup.

Product Details

This FAST EZ-EFI 1.0 ECU programmer utilizes a wide-band oxygen sensor for closed-loop fuel control, meaning it constantly monitors your exhaust gases and makes real-time adjustments to the fuel mixture. This advanced approach helps ensure your engine is running at its optimal air-fuel ratio, which can lead to improved performance and efficiency. It's designed to simplify the process of converting older carbureted engines to electronic fuel injection, making it a popular choice for a wide variety of vehicles. For example, it fits many classic Chevrolet trucks like the C10 and K10 from the 1980s, as well as cars like the Camaro and Caprice from the same era, and even some earlier Avanti II models.

The EZ-EFI system is known for its user-friendly setup. It comes with a pre-programmed base map that works well for many common engine combinations, and the system learns and adapts as you drive. This means you don't necessarily need to be a tuning expert to get your engine running smoothly. The ECU itself is a well-built unit designed to handle the demands of engine management, and it integrates the wide-band sensor input directly for precise fuel metering. This closed-loop capability is key to maintaining consistent performance across different driving conditions and altitudes.

When installing this system, you'll be replacing your carburetor and associated fuel lines with the EFI throttle body and fuel system components. The ECU will manage fuel delivery, ignition timing (if used with a compatible ignition system), and idle speed. It's a comprehensive solution for those looking to modernize their vehicle's fuel system. Please note that this unit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation guide for specific details regarding your vehicle's setup and any additional components that may be required.
