mivec automatically adjusts cam timing as well as the high/low cam profile, resulting in a smoother transition in power, whereas vtec only controls the cam profile... howeva the new i-vtec is very similar to the mivec system in that it adjusts both as well, only mitsubishi had it 10 years ago... why it doesn't work better is a mystery
Its also interesting to see the new EVO will boast a turbo mivec engine, sumthin that only the aftermarket cater for, for hondas...
