who knows but just because vtec isnt making noise doesnt mean its not occuring. and butt dyno doesnt apply here.
n order for the ECU to initiate the VTEC system, 5 engine conditions must be met.
Temperature: The engine must have reached normal operating temperature.
Throttle Position: The throttle must be open far enough to allow for increased airflow in VTEC.
Vehicle Speed: The car must be in motion (wheels spinning).
RPM: Engine must spin to it's target value. The GS-R will send it's "GO" signal for VTEC at 4400 RPM while the Type R sends it's signal at 5700 RPM.
Oil Pressure: The engine must be operating with normal and safe levels of oil pressure determined by the VTEC pressure switch.
The ECU will send a signal for a spool valve to open. When this valve opens, oil is allowed into the pivot shaft inside the valve rockers and directed into the center rocker. Inside the center rocker, a set of pins are forced outward by the oil pressure and lock inside the rockers to both sides. This entire process occurs in 1/10 of a second.

are you sure your car is warmed up all the way? is your check engine light on? maybe you are just imagining a problem
- how the hell are we supposed to tell from that damn video when or not you are trying to engage vtec or not

i was on the highway for about 20min so i know my car was warmed up no check engine light or anything like that and i think i know the y way my car sounds from one day to the other i have a SRI so Vtec is very noticable. Im sorry if i offended you with my "Stupid post /thread" but if your just trying to make me look dumb saying how the hell your supposed to know if im trying to engage vtec then i would rather you not post and id rather you not offer your advice i rather wait for people like tegsox or somebody a little more familiar with the situation to help. Thanks anyway though :thumbs up
