TECH – FAST EFI Solution: XFI SPORTSMAN

0

FAST has unveiled their Custom tunable EFI to bridge the gap between EZ-EFI and XFI 2.0 for specific use in drag race application and those looking for the solution to a solvable problem. Designed for muscle car, late model street and sportsman drag racing engines, along with boosted and individual runner throttle body applications, 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 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 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.

Data Logging • Nitrous Timing Retard • Boost Capable

The FAST™ XFI Sportsman™ 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. 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™, XIM™ and eDash means users can easily plug-and-play those components with the included CAN network wire. The FAST™ XFI Sportsman™ Engine Control System also features a Bosch wide-band 02 sensor, utilizes built-in diagnostic LEDs, a water-resistant ECU enclosure and includes a premium, mesh-type wire loom multi-port harness.

Multi-Port EFI or Use EZ-EFI Throttle Body

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 for electronic timing control with FAST™ distributors and crank triggers, EZ-LS™ and XIM™, or timing can be set with a standard carb-type distributor and the included tach adapter. The RPM/tach signal from an aftermarket CD ignition box is also a timing control option.
