it kicks in all the time, all vtecs... but its a matter of hearing it or not

i can hear it all the time, but when i floor that beast, it screams louder, just like a girl hahaha....... if you go soft on it, regular scream, if you go hard on it, real loud, consider you have I/H/E haha

well if everything works as it should vtec will kick in every time.
With a gsr you should hear two changes in the tone of the engine, 1 when vtec kicks in around 4400 and another 1 when the IABs open up around 5800 or so.

ill tell you right now, my lil jap motor doesnt like the cold. v-tec doesnt work untill she is warm, and i mean warm. i always let my car warm up in the morning, just so v-tec works when i drive. this was mostly in the winter. my car warms up now twice as fast and it kicks all the time. it should work all the time cuz if your car is warm you shouldnt be near 4800 rpm!

yeah from my understanding the jdm motors wait until the motor is warm (and honestly, you shouldn't be revving that high unless your motor is warm)

it also won't work if you don't have a knock sensor.

please correct me if i am wrong, cus i want to know this as well.
