It doesn't sound like your doing anything wrong. Maps do not usually come with the soft ware. Tune ecu has a page on their site with maps for various Triumphs. Or if someone has a map matching yours they can send it to you. Being its the first time you hooked up to the ecu I would ready the map that is in the bike so you have the original to go back to. any changes you want to do to it you will have to save the map so the changes take affect then load it into the ECU. Each time you save a map save it as a different name or like I do put the date in the name so you know which map is the most recent map.
I am not a android man but assume a lot of it is like using a laptop. I have heard that in order to do any mapping you will need to link up with the cable no wireless. I think you can monitor a lot of things wireless maybe even do some of the maintenance just not map changes.
Hopefully someone who uses the android will come along with some advice so I can learn and may get that also.
