    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.

    Hardware
    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.

    Technology
    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.

    Standard Features:
  • Built-in wide-band O2
  • Fully sequential or bank-to-bank capability
  • Individual cylinder correction
  • Fan and fuel pump control
  • Dynamic scaling of vectors in 2D & 3D tables

  • Automatic and manual TPS calibration modes
  • Additional transbrake control features
  • Improved on-board diagnostics

  • Can I use this on a chevy 350 engine if I change the intake manifold?

    Asked by: Areapolice
    This could be something you use. There's much more than just this needed.

    Can this be installed on a 1987 V10 with a stock 350 in it? What will I need to make a simple installation?

    Asked by: areapolice
    No that throttle body will not fit that engine.

    Can this item be used with any other manifolds?

    Asked by: Getdown
    This can be used on any manifold that will accept a 4150 style carb flange.
