XFI Sportsman

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.

For cars with an identity crisis (they don't know if they're a street car or a race car), XFI Sportsman electronic fuel injection systems fill a hole in the middle of the FAST lineup. They're designed to satisfy the enthusiast who does spend some time racing, but also spends time cruising. These EFI engine control systems will serve to simplify the tuning process and give you the capability to control the engine with greater control and precision than currently exists. When we say simple, we mean really simple--installation is a snap, and if you've ever worked with tuning software in the past, XFI's C-Com software will be familiar to you. If not, then you can use the self-tuning option and be off to the races as you learn the capabilities of your new system. The FAST systems ship with an ECU, wiring harnesses, wideband oxygen sensor, and electronic fuel pressure kit.
