Customizable Throttle Body EFI Bridging the Gap Between EZ-EFI and XFI 2.0
\n\nCrafted for muscle car enthusiasts, late-model street cruisers, racers, and sportsman drag racing aficionados, the FAST™ XFI Sportsman™ Engine Control System is a fully customizable EFI solution. Tuning requires a laptop, utilizing the reliable FAST™ C-Com® software bundled with the essential USB connectivity cable. Offering both load-indexed speed density and Alpha-N tuning strategies, with most users favoring speed density, the Alpha-N option caters specifically to Sportsman drag racers seeking unwavering consistency.

- Data Logging Capability \n
- Nitrous and Boost Compatibility \n
- Fuel and Timing Control or Fuel-Only Option \n
The FAST™ XFI Sportsman™ System includes comprehensive tables for monitoring fueling, acceleration fuel, timing, and air/fuel targets. A user-configurable auxiliary input channel and full-function data logging are part of the package. It supports both naturally aspirated and boosted applications up to 5 bar, is compatible with wet nitrous, and features nitrous timing retard control. The built-in CAN network support for EZ-TCU™, EZ-LS™, XIM™, and eDash allows seamless plug-and-play integration with these components using the included CAN network wire. The FAST™ XFI Sportsman™ Engine Control System incorporates a Bosch wide-band O2 sensor, waterproof ECU enclosure, built-in diagnostic LEDs, and includes a premium mesh-type wire loom multi-port harness. It is compatible 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. Alternatively, it can control fuel only, working with a standard carb-type distributor (e.g., HEI) where timing is manually set.
\n\nStock-to-1200HP Throttle Body with Integral Pulse Damper Supporting Return or Returnless Fueling
\n\nThe eight-injector, die-cast throttle body (similar to the one available with EZ-EFI 2.0®) uses commonly available late-model OEM sensors for accuracy and durability, accommodating engines from stock to 1200 horsepower, the highest in the market. Improved inlet design enhances airflow compared to the first-generation EZ-EFI® throttle body, and a new secondary shaft throttle stop adjustment allows more precise idle airflow adjustment and balance. The exclusive-to-FAST™ integrated fuel pulse damper ensures ultra-precise fuel control and supports both return and returnless style fuel systems. This throttle body features needle-bearing supported shafts, an integrated fuel rail design with crossover for compact packaging, and includes the market's fewest connection wires.
