FAST 304003 EFI Kits

The XFI Street Upgrade Kit contains everything needed to take your EZ-EFI Fuel to the next level. Including a new ECU, C-Com software and a communication cable, this kit is the most cost-effective way to make your EZ-EFI laptop tunable.. See 304001 for XFI Street Engine Management System with 4150-Flange EZ-EFI Fuel Throttle Body.

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.
