VTEC is ONLY supposed to turn on at times, not from when the engine is turned on. VTEC is actuated by oil pressure and RPM. Once a certain RPM and pressure is reached, VTEC engages.
DO NOT, I REPEAT, DO NOT CHANGE YOUR VTEC CROSSOVER POINT!

It's VTEC. VTEC doesn't "open", it is a process that is activated when your VTEC solenoid links the rockers in the head to increase duration and lift of the camshaft. If VTEC isn't working all the time it's probably because you have a jury-rigged shitbox mini-me instead of one that's properly done. Maybe you're trying to run hard when the engine is cold or otherwise lacking in certain vital areas...I'm not sure because I'm not you.

Yes, among idiots these days, it is. Unless the engine it is changed on has EXTEME internal modifications and is very well tuned. Changing the VTEC crossover point is pointless and harmful to the engine. It will actually (in some or most cases) cause a lose of power.

Re: (DOHC4life)
I'm gonna back him up here. Your engine was OPTIMISED at that RPM to change cam profiles (engage VTEC). So unless you change your cam, and/or change like piston rod length, AND your engine was upgraded to handle any possible added stress, Yeah, DON'T CHANGE YOUR VTEC ENGAGEMENT RPM. Thats advice that will save you a headache and money.

Correct. You can end up haveing a loss inpower or even a blown motor if you do not do this properly.
