OK, I'm with you now. You had two sepearate issues.
I have had the no start issue due to a weak battery. After some research I found the low voltage can cause it to go into flash mode, thus the no start. I actually was glad it did that so there would be no way to make a pass without proper voltage.
I can see where the ignition sequence was the likely culprit. Thanks for the info. Sorry this happened but I still don't see a real reason to bash XFI. It was some type of electronic malfunction which can or has happened to other boxes at some time or another, XFI, Bigstuff or like my buddies MSD. When you sit down and think about what gets our cars from a to b it should scare all of us into another hobby. Good luck.
I really don't see the problem putting this mishap to light and with a conclusive reason. If everybody kept these things quiet others may not realize the strange things this box does and learn from it.
I'm sorry if FAST doesn't like it, but I am the guy paying the bill here and if they don't like the truth told about the product they sell and profit from then I suggest start compensating the customer like most REAL businesses do.
