FAST ECU FAST With Internal Data

FAST is known for creating advanced engine management systems, and their XFI 2.0 ECU is a prime example of that expertise. This unit is built for serious performance tuning, offering expanded functions and adjustability for power adders like turbochargers and superchargers. It's designed to give you precise control over both fuel and spark, helping to eliminate flat spots in your power curve and achieve optimal performance.

The XFI 2.0 includes advanced features for racing, such as two separate, programmable sequential rev limiters with multiple activation options and modes for staging or boost building. It also has a time-based boost controller and options for fixed VE or timing during boost building, which helps with staging repeatability. For power adders, you get expanded progressive controls for both wet and dry systems, including a dry power adder fuel delay to correct rich spikes when the system activates. The system also offers a self-learning auto-tuning VE table that can quickly create a base fuel map, which you can then turn off for manual fine-tuning if you prefer.

This ECU also includes user-adjustable solenoid pulse frequency for better control of power adder solenoids and offers a choice between fixed target air/fuel or standard air/fuel tables for correction. Keep in mind that this system is not CARB approved and cannot be shipped to California. It's a powerful tool for anyone looking to fine-tune their engine's performance with advanced EFI capabilities.
