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. FAST engineers have designed an all-new laptop-tunable ECU to appeal to customers and dealers with simple EFI needs, but who prefer the greater flexibility afforded by laptop tuning. 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. The unit is offered in kit form with a multi-port harness or with an EZ-EFI four-injector throttle body and harness. A retrofit kit is also available for adding an XFI Street ECU to an existing EZ-EFI installation.
