NOTE: The above is a start. The actual data base given via their link is missing a few bits of data. The original instruction stated to: 1- Select "Quick Guides"; 2- Open "Latest Calibration Informaton" with a side note of scrolling down and opening the x-cell page. Utilizing that data in the x-cell you can find out if you have the latest "Flash". Well the document does not show an x-cell page but the link as given above. Not sure if this is because the engine is fairly new or what so I copied it from another site for the actual x-cell document. You have to down load and save it. ( http://www.motorcraftservice.com/vdi...alibration.xls ). The problem with that document is that it only goes up to 2009 on the Super Duty. SO I am at a impass currently. Does anyone have better working knowledge of this matter?
