FAST ECU FAST W/Int Data Log

The FAST XFI 2.0 ECU is an advanced engine control unit designed for high-performance applications, especially those involving forced induction and racing strategies. It offers significantly improved and expanded functions, capabilities, and adjustability over previous models, with a user interface that's been updated for power adders. This system aims to eliminate flat spots in the power curve by providing faster processing and more precise control over fuel and spark.

One of the standout features is the self-tuning option, which automates the process of fuel mapping, making it easier to get a solid base tune. This automated process can be turned off if you prefer to manually fine-tune the system. For those running advanced setups, the XFI 2.0 includes specific controls for forced induction, like a time-based boost controller and user-selectable fixed VE or timing for staging. It also offers advanced features for progressive power adders, supporting both wet and dry applications with adjustable fuel delays for dry systems to prevent rich spikes upon activation. The system also includes separate tables for power adder solenoid and fuel control, and allows for user-adjustable solenoid pulse frequency for better controllability.

Beyond engine tuning, the XFI 2.0 includes features like Qwik Tune Technology and even Trans Brake Controls, positioning it at the forefront of aftermarket EFI systems. It's important to note that this system is not CARB approved and cannot be shipped to California.
