This is how I was told it was, I'm not sure who is doing the reflash (As in if its someone from Nengun or some tech firm in Japan doing it) but they wont release the data to update it to the power FC for yourself (For obvious reasons) which is the main reason i was put off
Other then that the kit comes with map sensor IAT sensor and everything you need to plug it in and go
Having said that though, I cant find it on the Nengun site anymore.....
