Features
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.

The FAST XFI Sportsman roots blower dual quad EFI systems are a custom-tunable throttle body EFI that fills the gap between FAST EZ-EFI and XFI 2.0 systems. Designed specifically for roots blowers on muscle car, late model street, race and sportsman drag racing engines, the XFI Sportsman system is a fully software-tunable EFI setup. It requires a laptop for tuning and uses proven FAST C-Com software, which comes packaged along with the necessary USB connectivity cable. The system offers both load-indexed speed density or Alpha-N tuning strategies; most users will use speed density strategy which is self tuning, but the Alpha-N option is specifically added to serve Sportsman drag racers looking for absolute consistency.
The FAST XFI Sportsman roots blower dual quad EFI system features full tables to monitor fueling, acceleration fuel, timing and air/fuel targets. A user-configurable auxiliary input channel and full-function data logging are also included. Built-in CAN network support for the EZ-TCU, EZ-LS, XIM, and eDash means users can easily plug-and-play those components with the included CAN network wire. XFI Sportsman also features a Bosch wide-band oxygen sensor, utilizes built-in diagnostic LEDs, a waterproof ECU enclosure, and includes a premium, mesh-type wire loom multi-port harness. Plug-and-play with FAST distributors, EZ-LS or XIM for electronic timing control--or it can be used with an EFI distributor of your choice and a FAST crank trigger. The system can be used to control fuel only and be used with a standard carb-type distributor where timing is set manually.
The dual quad throttle bodies feature commonly available late model OEM sensors for accuracy and durability--and support from stock to 1,000 hp engines. It flows more air than the first generation EZ-EFI throttle bodies due to an improved inlet, while a new secondary shaft throttle stop adjustment provides even more precise idle airflow adjustment and balance. Meanwhile, an industry exclusive and unique-to-FAST integrated fuel pulse damper creates ultra-precise fuel control and allows return or return-less style fuel systems to be used. This throttle body also incorporates needle-bearing supported shafts instead of bushings and an integrated fuel rail design with crossover for tighter packaging. Setup includes the market's fewest connection wires.
FAST XFI Sportsman roots blower dual quad EFI systems are designed to be one of the most flexible systems available. It does matter if you are a weekend cruiser or the most demanding Sportsman class racer: FAST has you covered.
