Frequently Asked Questions<br />
What are the advantages and differences between the new XFI unit and my older style “classic” FAST system?<br />
The XFI computer processor is four times faster than the “classic” system, allowing it to control more features simultaneously. The new XFI system uses a 104<br />
pin wire harness versus a 60 pin wire harness on the “classic” system; again, these additional pins allow more features and devices to be controlled by the XFI .<br />
Additionally, performance features that had to be purchased separately with the “classic” FAST system are now included with XFI at no additional cost. Just<br />
click on the features you want to control in the included tuning software, i.e. four stage power adder control, boost control, traction control, etc. The XFI can also<br />
be run in either batch fire or sequential mode. If you choose sequential mode, you will automatically have individual cylinder control of both spark and fuel.<br />
Can my older “classic” FAST system be upgraded to an XFI ?<br />
Due to design differences, the “classic” FAST system cannot be upgraded to an XFI . You will be required to purchase both a new ECU and wiring harness.<br />
With the new XFI system, do I need a separate data logger?<br />
The XFI can be purchased with or without Internal Data Logging (See page 5). If purchased without the data logging feature, the XFI will record to a laptop when<br />
connected. FAST also offers an easy-to-use external data logger that simply plugs into the XFI . The external data logger will record up to one hour of data and<br />
does not require the use of a laptop (See page 9).<br />
I have an XFI but I would like to have some of the newer options such as Internal Data Logging and/or Intelligent Traction<br />
Control . Can I add these options to my existing XFI ECU?<br />
The answer is yes. Internal Data Logging can be added as a download via e-mail, or FAST can send a CD with the necessary option file. To upgrade an existing<br />
XFI to Intelligent Traction Control , you will need to send in the ECU, and FAST will upgrade it with the option file and a new billet enclosure that clearly identifies<br />
the ECU as having this option. You must call first and obtain a Return Authorization Number before sending an ECU in for this upgrade. For more information<br />
about either of these upgrade options, see pages 5 and 6 of this <strong>catalog</strong>, call us at 1-877-334-8355 or email us at tech@fuelairspark.com.<br />
Can I have my XFI upgraded to ITC (Intelligent Traction Control ) without changing the enclosure?<br />
Each and every XFI that has the ITC option must be in a black billet ITC enclosure. In addition to this, there is an ITC-specific LED sequence that appears at key<br />
on. This allows tech officials to identify an ECU with the Intelligent Traction Control option.<br />
Is Intelligent Traction Control legal in my class<br />
ITC is not legal in all sanctioning bodies/classes. It is the user’s responsibility to check with his or her sanctioning body to make sure that an electronic traction<br />
control device is legal in competition.<br />
What hardware is required to use the Intelligent Traction Control ?<br />
The only device required to take advantage of our ITC technology is a driveshaft speed sensor. See page 7 of this <strong>catalog</strong> for driveshaft speed sensor kits.<br />
What’s the difference between “batch firing” or “bank-to-bank” vs. “sequential” systems? Which do I need?<br />
Batch fire systems fire all the injectors simultaneously. Bank-to-bank systems fire the fuel injectors in “banks”; half of them fire on one engine revolution and<br />
the other half fire the next engine revolution. A sequential system fires the fuel injector for each individual cylinder in the firing order of the engine. In most cases,<br />
bank firing will be fine, but if you’re using an extremely radical camshaft, high boost, or over 600 horsepower, you might find sequential to be a slightly better fit.<br />
It will usually make marginally more power and help some radical engines idle better.<br />
