I drive a 2005 accord, it's smooooooooooth as can benow to yr question, this stands for vraible timing electronic combustion, what used to be is that the ignition is tied up mechanically to the cranck shaft so that it takes place while the engine is at a certain stage of the combustion cycle. By controlling it electronically, engineers are able to alter that by a few milliiseconds to start or delay the process of ignition in order to deliver better performance fm the engine....hope that helps, have a nice day;-)

VTEC itself has very little to do with actual electronic ignition timing. It has a lot to due with the mechanical valve timing. On my 2001 Accord, only 1 of the valves reach full stroke below 3500 rpm. This allows the engine to produce better low end torque. Above 3500 rpm the VTEC solenoid engages some dohicky via the oil pressure and both valves run 1:1 full/max stroke. It's a little bit different on other cars; not all VTEC is the same.

(V)arible valve (T)iming & (E)lectronic lift (C)ontrol. there is no such animal as electronic cumbustion in car engines! when valve actuation is set for low rpm, timing and lift, low rpm torque is better than in standard engine. when valve actuaction is then switched for high rpm timing and lift, output improves to the level given by a racing engine! until honda few varible valve timing systems have been comercialized. hondas system is the first in the world in which both valve timing and the degree of valve lift can be changed as needed.
