To be honest, I dont have a clue what flash is in the box. How do I re-flash it? I read up a little on this and it seems like I have to flash it before I connect it? What is the correct process to do this and how do I know it is the correct flash?
I have windos Vista, which I have heard may be a problem?
I have the USB adapter from Fast and I downloaded the disc that came with it.
Per the "help" section in the XFI software... which I feel is an excellent source of info... they did a good job on it...
26.0 Flashing Updates into your XFI™
26.1 Overview
Your new FAST XFI™ is “in field flash-able”. That means that as we come up with ways to make your XFI™ work smarter, faster or do things we haven’t even thought of yet, you’ll be able to simply download the updates from our website and “flash” them into your XFI™’s ECU from your computer. You never have to remove the ECU from your vehicle. It’s just that simple! Below we’ll walk you through the steps to a successful “flash”.
26.2 Downloading a Flash update
First start by going to our website,
FUEL AIR SPARK TECHNOLOGY, and check for the latest update. It will look like “flash_update_1A.xfi”. Save the flash update file to C:\CComWP XFI. NOTE - If a message pops up stating that the file already exists and asking if you’d like to replace the existing file, you can click on Cancel since you already have the latest flash update file. You are now done downloading the Flash update.
26.3 Flashing the update into your ECU
To “flash” the update file into your XFI™ ECU, please follow these simple steps:
Connect your computer to the ECU with the supplied Communication cable
With the ignition switch in the off position, ground the blue wire found in pin A of the DIAG connector in your XFI harness or pin A21 of the ECU main connector.
Turn the ignition switch to on but do not start the engine. The CRANK LED on the face of your ECU should start flashing.
In the C-Com WP XFI™ software, click on FILE/Flash XFI ECU…
In the lower left hand corner you will see a message stating “Flashing ECU” and the progress bar in the right hand corner will show that it’s loading also. This will usually happen very quickly so you may not have time to see them.
You will then see a “Verifying Flash” message in the same place in the lower left hand corner along with the progress bar in the right hand corner as in step 5.
You will now see a message asking you to “Restart the ECU”.
Turn the ignition switch to off.
Unground the blue wire from step number 2.
The ECU can now be restarted. You are now done updating the ECU.
