Nothing against your banana....I like bananas too.
Toyota also uses VVTi, though. They change valve timing and fuel mapping, similar to VTEC, but it also maps out how you drive and adjusts the A/F for power or efficiency depending on what it
thinks you want.
I'm not sure how much of an effect it really has on power, but then again I don't know how much VTEC influences power either. Well, ok, I know that Toyota's VVTi can actually give you less power than your car is capable of if it thinks you want efficiency.......hmmm, I don't like that system.
