FAST XFI Sportsman Throttle Body Engine Control System

The FAST XFI Sportsman Engine Management System is a simple, programmable and custom-tunable unit designed to fill the space between the EZ-EFI 2.0 Fuel + Ignition and XFI 2.0 segments. A new version of the system now also features a throttle body.

Designed for muscle car, late model street and sportsman drag racing engines, along with boosted applications, the FAST XFI Sportsman Engine Management System is a bank-to-bank, fully software-tunable EFI setup. It requires a laptop for tuning and uses FAST C-Com software, which comes packaged along with a necessary USB connectivity cable. A new version of the system also includes a 4150-style, eight-injector, 1200-horsepower-capable throttle body to provide easy installation when upgrading a previously carbureted setup.

The system offers either load-indexed Speed Density or Alpha-N fuel strategies. Most users will use Speed Density, but the Alpha-N option is added to serve sportsman drag racers looking for absolute consistency. FAST XFI Sportsman 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. The system supports both naturally aspirated and boosted applications up to 5 bar, is compatible with wet nitrous and has nitrous timing retard control. Built-in CAN network support for the EZ-TCU, EZ-LS and XIM also means users can easily plug and play those components with the included CAN wire. FAST XFI Sportsman features a Bosch wide-band 02 sensor, a waterproof ECU enclosure, utilizes built-in diagnostic LEDs and includes a premium, mesh-type wire-loom multi-port harness.

Compatible with return-style and returnless fuel systems, XFI Sportsman is designed for use with high-impedance injectors, and works with a variety of multi-port systems. It is conveniently configurable to work with FAST distributors or crank triggers, EZ-LS or XIM. The RPM/tach signal from a FAST or other aftermarket CD ignition box is also a timing control option.
