FAST Upgrade Charge XFI 2.0 Firmware

This is a firmware update that brings your FAST XFI system up to version 2.0. It's designed to give you improved and expanded functions, capabilities, and adjustability over the previous version. The user interface has also been updated, making it easier to manage advanced features for power adders, forced induction, and racing strategies.

With faster processing, you can expect a more consistent power delivery without flat spots. The system includes a self-tuning option that helps accurately balance fuel and spark, allowing for precise control. You'll find advanced features like two programmable sequential rev limiters with multiple activation options and modes, a time-based boost controller, and user-selectable fixed VE or timing for boost building. It also offers expanded progressive power adder controls for wet or dry applications, including a dry power adder fuel delay to correct rich spikes.

The Self Learning Auto Tuning VE Table feature automates fuel mapping for quick setup, but you can turn it off if you prefer manual tuning. This self-learning mode can populate a base tune quickly and accurately, which you can then refine further. The system also includes separate tables for power adder solenoid and fuel control for precise dry power adder tuning, along with user-adjustable solenoid pulse frequency.
