A contracted acronym for Variable Valve Timing and Lift Electronic Control (as VVTLEC is a bit of a mouthful), the system basically works like this: the engine has two different cam profiles, and hydraulically shifts between them – the relatively economical profile is in operation up to 5,750rpm, at which point the manic, silly profile kicks in for higher lift and longer duration. In essence, this means that when you reach the point on the rev counter where in other cars you might be thinking about shifting up a gear, a VTEC motor suddenly provides you with oodles more screaming, rampaging horses.
The ECU minutely monitors oil pressure, engine temperature, vehicle speed, engine speed, and throttle position to allow an efficient shift between lobes at the point at which it…
