    Manufacturer's Part Number:

    FAST XFI 2.0 Electronic Fuel Injection Kits are bolt on fully sequential EFI on Small and Big Block Chevy and Small Block Ford engines from mild street rods to 1,000 HP all-out race cars. XFI Fuel Injection Kits include carefully matched components, including the XFI, Dual-Sync Distributor, a single plane aluminum intake manifold, 4 barrel throttle body, proper size Precision-Flow Fuel Injectors, aluminum fuel rails, fuel pump kit, all necessary sensors, professional quality wiring harnesses with labeled connectors and the FAST EFI Installation & Tuning DVD.


    The XFI 2.0 uses the latest in flash microprocessor technology to deliver a significant increase in processing speed. This means the XFI can process, analyze and adjust four times faster than previous EFI systems. In addition, a surface mount component circuit board and billet ECU enclosure give the XFI superior durability. And to simplify installation, FAST offers engine-specific XFI 2.0 Wiring Harnesses featuring clearly labeled connections.

    Software Advances:

    The C-Com XFI Windows-based software is easy to navigate and incorporates several previously unavailable features, such as field flashable capabilities that enable you to download the latest software updates via email or directly from the FAST website. Stay current without ever removing the XFI 2.0 from your vehicle.


    The XFI 2.0 features Qwik Tune Technology, which allows ECU programming without a laptop. Preprogram up to four different EFI MAPs, and select the tune-up you need with the flick of an in-car switch. Optimize one setting for everyday driving, others for racing conditions and still another for improved fuel economy. Other features include on-board diagnostics, EZ Test Indicator Lights, five bar MAP sensing and controls for your power adder and torque converter. The XFI 2.0 also offers enhanced data logging capabilities and memory for analyzing up to 8 additional monitored inputs.
