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 cutting edge self tuning option, this is the one EFI system with easy-to-use features and completely configurable capabilities that accurately balances fuel and spark, allowing you to fine tune and precisely control like never before. 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. 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.The Self Learning Auto Tuning VE Table is an 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.
