and the ZEM comes with base maps in the app as well as a huge number of application specific configurations available for free.
ZCONTROL is not real-time.. Its just a .bin file editor. Its the first step in a seemingly endless number of steps to get to where you need to be in order to properly and safely tune your Z - that's where the ZEM comes into play and I have used it to tune simple stage3 cars all the way up to our heavyweight 700+ RWHP beasts... I've tuned ~50 cars with it in the course of the last year and a half and the ZEMulator has continued to evolve as the experience carried on and it is the best of the best for the Z32 to date.
