FAST 301021 XFI to XFI 2.0 Firmware & Case/Enclosure Upgrade Kit

The FAST 301021 is the official upgrade package for existing XFI fuel injection system users who want to step up to the more powerful XFI 2.0 platform. This kit includes the XFI 2.0 firmware flash along with a replacement case and enclosure, allowing you to retain your current hardware investment while gaining all the advanced features of FAST's next-generation EFI control system.

XFI 2.0 Upgrade Features:

• Upgraded firmware transforms your existing XFI unit into a full XFI 2.0 system
• Includes replacement case and enclosure for updated XFI 2.0 form factor
• Self-Learning Auto Tuning VE Table — automated fuel mapping process for fast and accurate initial calibration
• Self-learning mode can be disabled for full manual tuning control or used to build a base tune before fine-tuning
• Dry power adder fuel delay (in milliseconds) to correct rich spikes on nitrous or supercharger activation
• Enhanced adjustability and tuning control over the original XFI platform
• Supports advanced boost, timing, and fuel control strategies available exclusively in XFI 2.0

The Self-Learning Auto Tuning VE Table is an automated process that makes initial fuel mapping quick and straightforward. Users can allow the system to populate a base tune automatically, then switch to manual control for fine-tuning and custom calibration — offering the best of both worlds for experienced and novice tuners alike.

No other aftermarket EFI upgrade matches the power, flexibility, and adjustability of the FAST XFI 2.0 platform. This upgrade kit is the ideal solution for racers and performance enthusiasts already running the original FAST XFI system who want to unlock the full capabilities of XFI 2.0 without purchasing an entirely new unit.
