I just read up on this on the FAST site...seems to allow self-tuning...The basic XFI has canned tables to choose from to help you get started. You will still need to do the basic set-up. I will be sending in my XFI in for the firmware upgrade. Mine is tuned, but I want to see if I can use it to improve my poor fuel economy a bit. You can revert back to your prior manual input settings if you don't want the self-tune program.
