Hey guys still trying to learn all this stuff on how to load tunes to my autocal from my tuner I get in my email. I just deleted my 14 Cummins. I have watched videos on how to put it to the autocal. Most are showing going to the efi explorer then going to the tune folder and drag it right into the window pane. I tried this and I got an error saying that the file was in the wrong format. My tuner sent the tune as a BBX file. I have seen some people going to the BBX tab and putting the tune in there somehow. I'm kinda lost, I would greatly appreciate the help. Thanks
