FiTech Go EFI: The Ultimate Self-Learning Solution

FiTech's Go EFI 4 (600hp) system is the popular choice for most street and street/strip Pontiacs. This system is designed to mimic the dimensions and bolt pattern of a traditional 4-barrel carburetor, simplifying installation.

Key Features of FiTech EFI:

• Self-Tuning ECU: The Electronic Control Unit (ECU) is mounted directly onto the throttle body itself, drastically simplifying wiring. After inputting basic engine data (displacement, cam type) into the handheld controller, the system uses a wide-band oxygen sensor to automatically adjust the fuel map as the car is driven, eliminating the need for complex tuning.

   
   

• Built-in Pressure Regulation: The Go EFI system includes a built-in fuel pressure regulator, reducing the number of external components required and simplifying the fuel line plumbing.

   

• High Horsepower Capacity: The standard Go EFI 4 is rated to support up to $600\text{hp}$, making it ideal for the vast majority of performance-built Pontiac stroker motors on pump gas. FiTech also offers higher-capacity systems, including the Go EFI 8 for extreme builds over $1000\text{hp}$.
