The motherland, LOL. I'm not in the USA but the ECM I am looking at is from the US.
Now I see what you are referring to with the cal info, that number is manually entered, it is not pulled from the file so don't rely on what is in there as gospel.

Funny thing is we can't win on that field, if we have all the service numbers people read that as 'this file will work in all those service numbers shown' or on the flip side like you've just seen with one number missing it's confusing as well.
