FAST Harness EZ-EFI Gen2 Main

The FAST EZ-EFI 2.0 Fuel + Ignition works with either generation of EZ-EFI throttle body, multi-port systems and Inglese throttle bodies and is compatible with multiple fuel pump options including in-tank, inline, high horsepower inline, return style and returnless style. Electronic fuel pressure measurement is standard on all kits, and each one works with a wet nitrous system, providing built-in nitrous timing retard and special nitrous AFR targeting. The EZ-Ignition can work with most common ignition systems, while precision control requires a FAST distributor or crank trigger.

Additional Information

This is the main harness that comes with all EZ Fuel + Ignition kits. This can be adapted to either our throttle body injection or multiport harnesses.

Vehicle Compatibility and Return Conditions.

This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.

Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.

Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.
