The ECU is mounted on the throttle body, simplifying installation

The ECU (computer) is mounted on the throttle body of the FiTech Mean Street 800 HP EFI Self Tuning Fuel Injection System. This design feature greatly simplifies the installation process. By mounting the ECU on the throttle body, there is no need to create a hole in the firewall and no unsightly harness draped across the engine. This simplifies the installation process by reducing the number of parts and steps required.

The ECU controls the fuel injection system, ensuring the precise delivery of fuel to the engine. By having the ECU in close proximity to the throttle body, the wiring between the two components is minimised, resulting in a cleaner and more streamlined installation. This also reduces the overall complexity of the system, making it easier to maintain and troubleshoot.

The throttle body is responsible for controlling the airflow into the engine, and by having the ECU mounted directly on it, the two components can work in tandem to optimise the air-fuel mixture. This results in improved engine performance, responsiveness, and fuel efficiency. The ECU can make real-time adjustments to the fuel injection system based on the airflow data it receives from the throttle body, ensuring that the engine always receives the optimal air-fuel mixture for its current operating conditions.

Additionally, the Mean Street 800 HP EFI Self Tuning Fuel Injection System features a built-in fuel pressure regulator, further simplifying the installation process. This regulator helps maintain the correct fuel pressure, ensuring that the injectors receive the proper fuel flow rate. By having the fuel pressure regulator integrated into the throttle body assembly, the overall footprint of the system is reduced, making it easier to install in tight engine compartments.

The ECU also features a hand-held controller with a touch screen for quick and easy initial setup. This allows users to easily configure the system according to their specific engine and vehicle requirements. The controller's touchscreen interface provides a user-friendly way to access the ECU's settings and make adjustments as needed, ensuring that the fuel injection system is properly calibrated for optimal performance.

The built-in fuel pressure regulator provides simple, clean wiring

The FiTech MeanStreet EFI 800 HP Fuel Injection System is a powerful and compact package that offers an impressive 800 HP. The system's built-in fuel pressure regulator, in conjunction with the onboard ECU, simplifies the installation process by providing simple and clean wiring.

The fuel pressure regulator is an essential component of any EFI system. It ensures that the fuel rail maintains sufficient pressure to meet the fuel demands of the injectors. Without it, the fuel would simply flow through the rail without reaching the injectors, resulting in insufficient fuel supply. Conversely, without proper regulation, the fuel pump may force too much fuel into the injectors, leading to potential failure.

The regulator works by maintaining a steady fuel supply, even during significant fluctuations in fuel demand. It consists of a diaphragm that controls the bypass valve, allowing it to adjust for steady fuel delivery. As pressure is applied to the regulator, a spring forces the diaphragm down, reducing excess fuel and making the fuel pumps work harder. This, in turn, leads to a linear increase in fuel pressure.

The built-in fuel pressure regulator in the FiTech MeanStreet EFI 800 HP Fuel Injection System ensures that the fuel supply is appropriately adapted to the engine's fuel demand. This results in a simple and clean wiring setup, making the installation process more accessible and efficient.

With the MeanStreet EFI 800 HP Fuel Injection System, you can expect not only impressive performance but also a streamlined and straightforward installation process, thanks to its built-in fuel pressure regulator.
