cuscostrutbrace,
so far, i think microtech and others stand alone ecu can control VVT ( silver top and black top ) but not VVt-I ( like Vios )
The technology for VVT-I just like ignition map or fuel map, it need a map or table to tune on it, its quit complex.
and i Motec ( high range, like M400,m600,M800 ) can do on this job but you have to add extra money, anyway, cuscostrutbrace, i think you can tune the Motec, right ?
Good Luck.
