" You can look at about 100 billion different things with the BT cable/software. Most are not helpful but for some science project troubleshooting things I've been doing.... immensely helpful. Very powerful stuff. I normally only use about 3% of its capability. "
" I understand what you're saying but my point is that back in 2012 and even the beginning of last year there were guys all over claiming to have this "hookup" at the dealer who would turn their car into a beast because it was the press tune. And then people started figuring out some M5s were making a ton more power than BMW said it was...and then we realized they all are because that's just what it does. I understand what you're saying completely...I guess my point is some people don't. There was a big, misinformed group of people that thought BMW was sending 750 hp M5s to the press and that if you had the right friends you could get this tune as well. No argument with you...I'm just kind of making a different point.
The small gains by that recent flash tune seem to look very much like the difference in the S63tu comp. tune, I could totally see that being the case here too. "
Yeah. Bavarian Tech is a different cable and does vin lock.
Burger Tuning (forum sponsor, pretty sure it's ok to link) sells a single-vin cable here: http://www.burgertuning.com/scanner.html. Of note, the BBFlash utility does not consume a VIN, but using the Bavarian Technic application will. "
