XFI Sportsman EFI System for GM LS Engines
Fully software-tunable EFI system designed for LS engines which features 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. KIT INCLUDES: XFI Sportsman™ ECU, EZ-LS® Ignition Control, Wide-Band 02 Sensor, Wiring Harness, Communications Cable and C-COM® Software
