FAST XFI Sportsman EFI System (GM LS)

The FAST XFI Sportsman EFI System for GM LS Applications is a fully software-tunable EFI system designed for LS engines. Featuring the XFI Sportsman ECU, this kit provides total flexibility in tuning and monitoring engine fueling, acceleration fuel, timing and air/fuel targets. While offering PC based, on-the-fly tuning, the system also provides a self-tuning strategy that can be enabled or disabled. 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 and is also 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.

Incorporating the proven EZ-LS Ignition Control for spark duties, the kit installs easily and allows you to fully control your LS engine. Tuning with the FAST system is done conveniently in real time, unlike inferior factory EFI based kits that require constant ECU reflashing whenever you want to make changes. The system 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 the choice of the load-indexed Speed Density fuel strategy for most users but also includes the option of the Alpha-N strategy that was specifically added to serve drag racers looking for absolute consistency.
