[QUOTE="Graybeard, post: 1704727, member: 49070"] I used a software tool called Accessport Manager to manage the tune files on your physical device via a computer and USB cable. This tool is really easy to use. I was pleasantly surprised that they have both Windows and OSX versions of their app. The OSX version installed and worked without issue. You can then drag and drop tune files into the Accessport just like it was a USB drive. When I plugged in the Accessport to the computer the first time, it backed up the factory tune to the computer. Nice touch. At the end of my tuning process I chose to do some file cleanup. I removed all datalogs to free up space on the device and then removed my test revisions of the tunes. I wanted to make it easy on myself in the future, so I retained only the FINAL versions of my tunes and even removed the original COBB engine tunes from the tool. I was worried that some day someone may accidentally flash a file for the old turbos and fueling system. That may be problematic. So, I backed these up on a computer and removed them from the mobile tool for safety. [B]So, how do I like it?[/B] I really like the exhaust sound.
