Unlocking Performance: FiTech Go EFI & Fuel Command

For enthusiasts of classic cars and hot rods, the pursuit of enhanced performance, improved drivability, and greater fuel efficiency often leads to a pivotal decision: converting from a carburettor to modern electronic fuel injection (EFI). While the benefits of EFI are undeniable – from crisp cold starts and smoother idle to better throttle response and automatic altitude compensation – the complexity of such a conversion has historically been a significant barrier. This is precisely where FiTech Fuel Injection steps in, offering innovative solutions designed to demystify and simplify the upgrade process. This article delves into two cornerstone components of the FiTech ecosystem: the FiTech Go EFI System and the ingenious FiTech Fuel Command Center, explaining how they work in harmony to bring contemporary fuel injection to your cherished vehicle with unprecedented simplicity.

Converting to EFI traditionally involves a comprehensive overhaul of your vehicle's fuel system. This often means installing a high-pressure electric fuel pump, running new high-pressure fuel lines, and, crucially, plumbing a dedicated fuel return line back to the tank to regulate fuel pressure. This return line requirement, in particular, can be a major headache, necessitating modifications to the fuel tank or the addition of a swirl pot, adding significant time, cost, and complexity to the installation. FiTech's approach aims to circumvent these common pitfalls, making EFI accessible to a broader range of DIY mechanics and professional installers alike.

What is the FiTech Go EFI System?

At its heart, the FiTech Go EFI System represents the vanguard of throttle body EFI technology. It's engineered to be the most advanced and, perhaps more importantly, the easiest throttle body EFI system to install on the market today. Unlike traditional port fuel injection systems that require individual injectors for each cylinder, the Go EFI system integrates the injectors directly into a throttle body unit that mounts onto your existing carburettor manifold. This design significantly reduces the complexity of installation, as it typically doesn't require manifold replacement or extensive wiring harnesses.

The Go EFI system comes equipped with a highly sophisticated handheld controller. This device isn't just for basic setup; it's a powerful tool that allows for initial calibration, real-time monitoring of engine parameters, and fine-tuning adjustments without the need for a laptop or complex software. The system is designed to be largely self-learning, meaning it can adapt to your engine's specific needs and driving conditions over time, continually optimising the air-fuel mixture for peak performance and efficiency. This adaptability is a massive advantage over carburettors, which are notoriously sensitive to changes in temperature, altitude, and engine modifications.

Key features of the FiTech Go EFI System include:

• Integrated ECU and sensors within the throttle body for a cleaner installation.
• Self-learning capability for optimal tuning.
• Advanced handheld controller for setup and monitoring.
• Designed to fit most carburettor manifolds, simplifying conversion.
• Capable of supporting a wide range of horsepower applications.

The system's modular design means that while it offers a basic installation kit, it also provides options for more comprehensive fuel delivery solutions, leading us directly to one of FiTech's most ingenious innovations: the Fuel Command Center.

The FiTech Fuel Command Center: Revolutionising Fuel Delivery

If the Go EFI system is the brain of your new fuel injection setup, the FiTech Fuel Command Center (FCC) is arguably its heart. Described as the "ultimate in a fuel delivery system," the FCC is designed to be the most efficient and simplest way to supply the necessary high-pressure fuel to your FiTech EFI system. Its primary advantage, and a truly revolutionary feature for EFI conversions, is its status as a returnless system. This means it completely eliminates the need for a fuel return line running back to the fuel tank, solving one of the most significant plumbing challenges associated with EFI upgrades.

The brilliance of the FCC lies in its ability to leverage your vehicle's existing components. It's designed to work with your stock fuel tank, your stock carburetted fuel pump, and your stock inlet fuel line. The installation process is remarkably straightforward: you simply disconnect the low-pressure fuel line that runs from your stock mechanical or electric carburetted pump to your old carburettor. This line is then redirected to the inlet port of the Fuel Command Center, which can be conveniently mounted in the engine compartment. The only additional plumbing required is a single high-pressure line from the FCC's outlet port to the inlet port on your FiTech Go EFI throttle body.

How the Fuel Command Center Works

The Fuel Command Center functions as a sophisticated sump tank. Inside, it contains an internal float mechanism that accurately controls the fuel level within the sump. Once the sump tank is filled by your vehicle's low-pressure carburetted fuel pump (which should not exceed 8 PSI), the float mechanism shuts off the incoming fuel flow. Submerged within this sump is a high-pressure 340 L/PH (litres per hour) fuel pump. Submerging the pump in fuel offers several critical advantages: it runs significantly quieter, operates at a cooler temperature, and consequently, enjoys a much longer lifespan compared to externally mounted pumps.

This internal high-pressure pump is capable of supplying sufficient fuel for engines producing up to 800 horsepower, yet it is also perfectly suitable for engines making as little as 200 horsepower. This wide operating range makes it incredibly versatile for a vast array of classic car applications. The FCC kit itself is comprehensive, typically including the sump tank assembly, the 340 L/PH fuel pump, an inline fuel filter, and all necessary EFI-grade hose and hose ends (push-lock style) for a complete installation. Some kits even include fuel pressure gauges for monitoring.

A critical point to remember for FCC installation is the requirement for a carburetted fuel pump (maximum 8 PSI) to feed the Command Center. Attempting to feed it with a high-pressure EFI pump will lead to issues and is not recommended.

FiTech Fuel Delivery Options: A Comparison

When considering an EFI conversion, understanding the differences in fuel delivery systems is paramount. FiTech simplifies this by offering the Fuel Command Center as its primary solution, contrasting sharply with the complexities of traditional high-pressure EFI setups.

As the table illustrates, the Fuel Command Center significantly reduces the barriers to EFI conversion by eliminating the need for complex return lines and extensive modifications to the original fuel tank and lines. This focus on convenience is a hallmark of FiTech's engineering philosophy.

Why Choose FiTech for Your EFI Conversion?

Beyond the technical specifications and ease of installation, opting for a FiTech Go EFI system paired with a Fuel Command Center brings a host of practical benefits to your vehicle:

• Improved Drivability: Say goodbye to flat spots, hesitation, and the need for manual choke adjustments. EFI provides smooth, consistent power delivery across the entire RPM range.
• Enhanced Fuel Economy: Precise fuel metering by the EFI system ensures that your engine receives exactly the right amount of fuel at all times, leading to better mileage compared to a carburettor.
• Reliable Cold Starts: EFI systems eliminate the struggle of cold starts, especially in varying temperatures, providing consistent ignition every time.
• Altitude Compensation: Unlike carburettors, EFI systems automatically adjust the air-fuel mixture for changes in altitude, ensuring optimal performance whether you're at sea level or traversing mountain passes.
• Reduced Emissions: A more precisely controlled combustion process can lead to lower tailpipe emissions, which is increasingly important in many regions.
• Simplified Tuning: The self-learning capability and handheld controller make initial setup and subsequent adjustments far simpler than traditional carburettor tuning.
