When it comes to tuning an EFI system, it's essential to understand the motors and the technology behind them. While EFI has many more controllable functions than a carburettor, the cost and complexity of adjustment can be much greater. To ensure that your EFI system is running at its peak efficiency, you'll need to supply it with the right fuel. In this article, we'll discuss the different types of fuel delivery systems available for EFI tuning and how to choose the right one for your vehicle.
Understanding EFI SystemsEFI systems come in a variety of packages, and the adjustment can be as simple as running a “learning mode”.
However, most engine manufacturers and tuners use an engine dynamometer or a chassis dynamometer to adjust their maps. Some systems also include a set of base maps to start with.
Fuel Lines for EFI SystemsThe typical EFI system requires a feed line to the EFI manifold and a return line to the tank. The throttle body is rated in cfm, and fuel injectors control the flow of fuel to the engine. In the past, many of the main EFI systems in the aftermarket were race-oriented and required a laptop even to start the car.
EFI Conversion KitsIn recent years, companies in the aftermarket have begun to simplify EFI exchanges by developing more easily adjustable systems that require less than a degree in electrical engineering.
The Edelbrock universal EFI sump kit is designed to provide the high-pressure fuel needed for EFI applications in vehicles that still use a mechanical fuel pump.
Types of Fuel Delivery Systems for EFI Tuning
Adjustable Fuel PumpAn adjustable fuel pump is one of the most common types of fuel delivery systems used for EFI tuning. It has an adjustable pump height and can be used in vehicles with mechanical fuel pumps. This type of pump is easy to install and adjust, making it ideal for those who are new to EFI tuning.
Fuel Pressure RegulatorA fuel pressure regulator is another type of fuel delivery system used for EFI tuning. This device regulates the pressure of the fuel going into the engine, ensuring that it is at an optimal level for maximum efficiency.
It is important to note that this type of system requires more maintenance than an adjustable fuel pump.
Fuel Injection SystemA fuel injection system is another type of fuel delivery system used for EFI tuning. This system uses an electronic control unit (ECU) to control the amount of fuel being injected into the engine. This type of system is more complex than an adjustable fuel pump or a fuel pressure regulator, but it offers more precise control over the amount of fuel being delivered.
Choosing The Right Fuel Delivery System For Your VehicleWhen selecting a fuel delivery system for your vehicle, it's important to consider your budget, your level of expertise, and your vehicle's specific needs. If you're new to EFI tuning, an adjustable fuel pump may be your best option as it is easy to install and adjust.
If you have more experience with EFI tuning, then a fuel injection system may be a better choice as it offers more precise control over the amount of fuel being delivered.No matter which type of fuel delivery system you choose, it's essential to make sure that it is compatible with your vehicle's specific needs. Be sure to read all instructions carefully before installing any type of system in your car.
