thought id post a solution seeing as the thread didnt end! when you plug in the box, you select which tune you want then turn on the ignition. the box will then start to flash, then flash 1,2,3,4 (might flash for a while depending which model you have, my BA tends to take a little while) now once its stops flashing 1,2,3,4, it will start blinking all at once. THIS DOESN'T MEAN ITS FINISHED, as of my understanding when its flashing 1,2,3,4 it's downloading your factory tune, then when it starts blinking, its actually uploading your tune. I found this out when I changed tunes and my car wouldnt start. I was then patient for a bit and waited til the box stopped all together. hope this helps anyone!
