I think I did a post back along about mapping stuff, which I said about the Potential Maps function.
Don't even bother with WinOLS recognising maps - a lot of the time they're unrelated maps, from memory it doesn't pick up half of the useful ones and half of the 'Statistical 16' maps are selected wrong. If you absolutely know what you're doing, it makes things easier to quickly select from the look of them and change the title - but none of the factors, offsets etc are there anyway which are needed to be able to interpret the maps.
There is no way of making it know what's related to what - that's the difficult part. You need to look at the shape of them, what the values are to maybe give yourself an idea of what they do - there's some brilliant PDFs out there all about EDC15 which explain most of the useful maps needed for a stage one, past there, you are on your own. Remember, not all maps have an axis defined in the normal way - they're often shared
As Poodle says, sign up to ecuedit, ecuconnections, chiptuners and there's a whole host of others which have loads and loads of information - more than you can ever imagine. A lot of the time you won't understand what stuff is about until you read the thread again and stuff starts to make sense.
The "number" next to the predicted maps is the map location - 0x4CA36 is a hexadecimal identifier for where the map starts in memory. Take a look at what Hexadecimal is and what that number is relating to
