6.7 Cummins I6
I know this is 5 months late but I recently acquired a black maxx it was on another truck, so I cleared out all the files and got the Cummins folder.

I used the updater to get them. I picked the first option was the H:// or something to that extent there's also a C:// what is that? I of course then clicked I had just an h&s black maxx, cause I don't think mine is a black maxx street. How would you find out the difference? Then clicked 6.7 cummins and gave me the files.

No my question is I see these people talking about running mild tune timing 3 no ATT, I understand the mild tune that's your buttons on the right, timing I know is an option when doing the download but what's the no ATT, how can that be clicked or not clicked?

Thanks in advance
