I have been comparing my first AB data to the most recent. That stuff is weird. I think when I tried to fix the lost radio tuner and out the original AB from July I was almost able to apply the 1.7.1 APIM usb from FDRS. It at least saw the data on the drive. Then I screwed up everything.
I did have more issues in forscan with nano than with super cheap off brand elm device. I might need someone to tell me how many modules I updated so I can apply older as built data. I only did a two day licence.
Any one care to share a decent forscan config? I now have a fancy AM radio that can do HD FM but I am not smart enough to get a good config done and have it stick.
