Building upon the success of the original FAST XFI, the new XFI 2.0 utilizes the latest in flash microprocessor technology and adds several features designed to provide users with more control over electronic fuel injection.

I've compiled a list of frequently asked questions:

1. What changes were made in the XFI 2.0?
XFI 2.0 adds several features to give users more control over their system. Along with a new self tuning option, the XFI 2.0 also includes advanced forced induction, progressive power adder and new race controls. For street customers, the biggest addition is the self learning feature.

2. What is the Self Learning Auto Tuning VE Table?
The Self Learning Auto Tuning VE Table has two components. The first is closed loop control using feedback from an oxygen sensor which has always been part of the XFI system.  Closed loop constantly makes fueling adjustments to compensate for different engine conditions. But this approach assumes a well tuned base VE/fuel table. The new Adaptive Learning aspect of the XFI 2.0 system actually changes the base VE table. This significantly reduces the amount of hand tuning that is required. After learning this process can be turned off.

3. What has been improved for racers?
XFI 2.0 boasts forced induction controls that include a time-based boost controller, user selectable fixed VE and/or fixed timing for boost building and staging repeatability. The progressive power adder controls include configurations for both wet and dry applications; separate tables for power adder solenoid control and fuel control; user adjustable solenoid pulse frequency; choice of fixed target air/fuel or standard air/fuel table; and a dry power adder fuel delay. All of these features offer racers more control than ever before for precision tuning.

4. Can the XFI 2.0 be preprogrammed?
All programming methods of the earlier XFI are still in effect

5. What original XFI features are included?
All of them.

6. How does the EZ-EFI and XFI differ?
The EZ EFI system is also self tuning but it does not require a laptop.  The EZ system does not control timing, is bank-to-bank only (no cam sensor means bank-to-bank), will not handle alternate fuels or a boosted engine.  Most street engines run very well with the EZ system.  All you need is a good tach signal.

The XFI is the high end solution that give you control over virtually all engine parameters. The XFI 2.0 can be made to work with virtually any engine combination. 2.0 is designed to handle more complex race applications such as boost, radically upgraded and nitrous equipped engines, and flex fuels, just to name a few. No matter what you have under the hood, the XFI can handle it.  It does require the use of a laptop.

7. How do I choose which components are part of my XFI 2.0 system?
Call or email me and I'll call you back to discuss your application.  From that I can make the correct suggestion on which way you should go.

8. What is the cost of the XFI 2.0?
FAST did not raise the price of the XFI 2.0 over the original. Even with all of the new features that were added to the platform, the cost has stayed the same. All XFI units now include XFI 2.0 software. However, upgrading an existing XFI unit to the XFI 2.0 software will cost $50.

10. Are there any options available for XFI 2.0?
* Internal Data Logging (IDL) allows datalogging without using a laptop.  This is important to racers. IDL allows recording of up to 24 input channels and sensors to create a comprehensive picture of what is happening.

* Intelligent Traction Control (ITC) solves the problem of lost traction resulting from trying to put too much engine power to the ground with too little tire. 

* The 16 injector option allows the injector drivers to operate up to 16 injectors and includes the injector Y adapter.

11. Where should I turn if I have more questions or need help?
Do you really have to ask?
