FAST Fuel Injection System

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.
