Dude, I have been advised to use DIS to calibrate my air suspension. I haven't personally used either software. With regards to the ipad capability, I doubt any of the software will work on ipad, I believe they only work on PC with windows XP OS. I stand corrected. do more research on this site or look at here: http://www.bimmerforums.com/forum/fo...ostic-Software

I hope i'm not violating forum rules by posting other bmw forum site.
