Thanks a lot for the tutorial. The difficult part is the one you linked to in part 2. The first one is pretty much the same for setting up Facebook ads for Heyzap for example. Will take a look at it. The idea is that once you have set it up properly you can track the installs made with the ads in facebook. Carter showed that they can be as low as $0.06 wich would be amazing if we can replicate this. Nonetheless, it seems this is not what you have set up since you weren't able to track installs, right?
