  • Designed for muscle car, late model street and sportsman drag racing engines, along with boosted and individual runner throttle bodyapplications, the FAST XFI Sportsman Engine Control 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 the necessary USB connectivity cable. A version of the system is now available that includes a 4150-style, eight-injector, 1200-horsepower-capable throttle body to provide easy installation when upgrading a previously carbureted setup. A user-configurable auxiliary input channel is included as well. The system offers both load-indexed Speed Density or Alpha-N fuel strategies
  • most users will use Speed Density but the Alpha-N option is specifically added to serve sportsman drag racers looking for absolute consistency. The FAST XFI Sportsman System features full tables to monitor fueling, acceleration fuel, timing and air/fuel targets, while full function data logging is also included. It 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 means users can easily plug-and-play those components with the included CAN wire. The FAST XFI Sportsman Engine Management System 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. 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 or either generation of the FAST EZ-EFI throttle body. XFI Sportsman is conveniently configurable to work with FAST distributors, FAST crank triggers, EZ-LS, XIM or the RPM/tach signal from an aftermarket CD ignition box, HEI big cap distributor or included tach adapter.
