|FAST™ engineers designed the revolutionary XFI 2.0™ with improved and expanded functions, capabilities and adjustability. In addition, they upgraded the user interface for power adders, including advanced forced induction, progressive controllability and other advanced racing specific strategies and features. Faster processing means no more flat spots in the power curve or settling for “close enough.” With a revolutionary new self tuning option, this is the one EFI system with the easy-to-use features and completely configurable capabilities that accurately balance fuel and spark, allowing you to fine tune and precisely control like never before.|
Advanced Forced Induction, Power Adder & Race Controls
The Advanced Forced Induction, Power Adder and Race Controls include two separate, fully programmable sequential rev limiters for staging or boost building with six options for activation, four priority assignments and a user selectable sequential or random mode for rev limiting. The Advanced Forced Induction Controls include a time based boost controller, user selectable fixed VE and/or fixed timing for boost building and staging repeatability. Newly expanded Progressive Power Adder Controls include configurations for both wet or dry applications; separate tables for power adder solenoid control and fuel control for perfect dry power adder tuning; user adjustable solenoid pulse frequency for optimum solenoid controllability; choice of fixed target air/fuel or standard air/fuel table for correction; and a dry power adder fuel delay in milliseconds for correcting rich spikes on activation. No other system matches the power and adjustability of XFI 2.0™.
Self Learning Auto Tuning VE Table
The Self Learning Auto Tuning VE Table is a new automated process option that makes for quick and easy fuel mapping with the XFI 2.0™. However, this option can be turned off should the user prefer to do the tuning manually. The self learning mode can also be used to speedily and accurately populate a base tune and then turned off for more fine tuning or custom control by the user – it’s all up to you when and how you want to use it. The C-Com® software features enable conditions to turn it on/off automatically and also has an overall enable/disable feature. Requires suitable PC for use.
The XFI 2.0™ uses the latest in flash microprocessor technology to deliver a significantly faster processing speed. It processes, analyzes and adjusts four times faster than previous EFI systems. In addition, a surface mount component circuit board and billet ECU enclosure give the XFI 2.0™ superior durability. And to simplify installation, FAST™ offers engine-specific wiring harnesses with clearly labeled connections.
The C-Com® XFI™ Windows-based software is easy to navigate and incorporates field flashable capabilities that enable you to download the latest software updates via email or directly from the FAST™ website. Your system will stay current without ever needing to remove the XFI 2.0™ from your vehicle.
The XFI 2.0™ features Qwik Tune™ Technology that allows ECU programming without a laptop. Preprogram up to four different EFI MAPs. You can optimize one setting for everyday driving, others for racing conditions and still another for improved fuel economy. Simply select the tune-up you need with the flip of an in-car switch. Other features include on-board diagnostics, EZ Test™ Indicator Lights, five bar MAP sensing and controls for your power adder and torque converter.
