That's not really how it all works unless something has changed. The maps are locked to a specific account where they are created. Unless they are uploaded to the map share, you will not be able to open anything emailed to you and use it. Someone would have to provide you with the data out of each individual map and then you could hand edit them into yours if you felt the need. But getting something emailed to you will be useless.
Yes, the map I referred to is uploaded on mapshare, from where I applied it. The TPS map on it is a tuned one, while the IAP and fuel trim maps are stock.
