Okay, so we hear all the time about the wonders of VTEC... Which is a system in Honda petrol engines where the valves lift higher when the engine exceeds a set RPM level ((4750?) to let more air/fuel mix in and more exhaust gases out... But how do people get it going? Let's say you're at traffic lights... Do you just take the needle up to the start of the red zone in first, then change up and take it up to the start of the red zone in the other gears? Or is there more to it than that?
