  • Regular price $890.95


The latest fuel delivery system from FAST is a tunable ECU based on EZ-EFI Fuel hardware and harnessing, but with learning capability similar to XFI Sportsman™ and XFI 2.0™ options. The XFI Street™ Engine Management System provides a cost-effective option for those customers who don’t need the most high-end system, but want complete control. Since XFI Street™ uses the same wiring as the EZ-EFI, it could easily be installed in place of an existing EZ-EFI ECU. Utilizing included C-Com software, XFI Street™ can easily deal with even the most challenging engine combinations. The XFI Street™ Engine Management System has data logging capability when connected to a laptop. It is intended only for naturally aspirated engines. In this kit, the unit comes with an EZ-EFI four-injector throttle body and harness. Also available with a multi-port harness or in a retrofit kit for adding an XFI Street™ ECU to an existing EZ-EFI installation.
