FAST XFI Street Engine Management System (Retrofit Kit)

The latest fuel delivery system from FAST is a tunable ECU based on EZ-EFI Fuel hardware and harnessing, but has learning capability similar to XFI Sportsman and XFI 2.0 options.

The engineers at FAST designed this 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 also 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 be used to tune an engine whose characteristics are not ideal for the self-tuning features EZ-EFI provides. The XFI Street Engine Management System has data logging capability when connected to a laptop. The unit is offered in kits with an EZ four-injector throttle body and with or without a multi-port harness. It is intended only for naturally aspirated engines.
