Show original supplier description
The FiTech Go EFI 4 Matte Black Self-Tuning Fuel Injection system is designed to enhance performance for a wide range of vehicles, from daily drivers to street machines and bracket racers. Rated for up to 600 horsepower, it is suitable for engines producing between 200hp and 600hp. This self-contained unit features the fastest self-learning technology available, integrated timing control, and wet flow annular discharge injectors. Installation is streamlined as the ECU is mounted directly onto the throttle body, negating the need for firewall penetration or complex engine bay wiring. This design also uniquely provides spark control without requiring an external spark box or specialized distributor, and includes a built-in fuel pressure regulator. The system utilizes a speed-density (Map-N) metering style and a 4-barrel square bore throttle body mounting flange, with four 43mm venturi openings and an 850 cfm airflow rate. The throttle body is constructed from cast aluminum and finished in matte black. A included handheld controller with a touchscreen interface simplifies the initial setup process. The kit comes complete with the die-cast throttle body, O2 bung kit, handheld controller and cable, CTS sensor and adapter, windshield mount, mini USB cable, a 4+2-pin connector, return plug, O2 sensor, and gasket kit. It is compatible with various fuel types including alcohol, gasoline, methanol, and flex fuels. This system is intended for retrofit into vehicles that do not require emission controls and is not legal for use on pollution-controlled vehicles.
