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 for specifically for roots blowers on muscle car, late model street, race and sportsman drag racing engines, the FAST XFI Sportsman EFI 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. The FAST XFI Sportsman also features a Bosch wide-band 02 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 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 features commonly available late model OEM sensors for accuracy and durability and supports from stock to 1000 horsepower 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 returnless 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. The 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.
