Uh, it's not that hard. The EMU will hook right up to the 7M but you need to use a different car with the KV afm and 6 cylinders. I think it might be the Dodge/Mitsubishi 3000GT that uses this setup.
From there you load it up in your laptop and begin to tune.
The only thing that people are having problems with is setting up speed density because there is no base map. However, the Emanage Ultimate will work fine. I don't know why people keep saying that it wont, I bet they don't have one.
It mostly works, it will just take a lot of time and work with the map to get the speed density mode to work.
