sorry so late but I just became a member. i was talking to some tech guy at Nismo and he told me that unichip (Dastek) was coming out with one. so I called them to ask and they said "it is not in nexy 50 cars but we will be doing one in the future"
this 50 cars will last for approx. 6 months so hopefully we will be in the next 50
if my calculations are correct around april or May
I'm waiting also If they e-mail me back with more info I'll let you know.
