Identifying maps in WinOLS

From what I have watched from the WinOLS courses, I have now understood how WinOLS works and how to find maps which we know the looks of, but my question is how do I find maps which I don't even know the look of or the address of. For instance, I currently am trying to make a mappack for my Dodge Journey 2.0 crd which has a bosch edc16u31 ecu and I cannot find absolutely any info on it online.

I'm only giving that as an example, but what would you guys do in such a situation?

Hopefully I just missed something in the course, but at the moment I'm completely in the blind on how to do this, if anyone can help I'll be very grateful!

Hi, the maps will all be in there, If you get stuck, email the original file with all the relevant information to support and we can arrange a mappack to be created for purchase on the HPA OLS reseller database.
