Default loss of Rpm is this possible?

Lately since I have been out driving I can do roughly 60 to 80 kph in second gear but lately When I try to go into v-tec my engine sounds like it is going to explode because of the high rpm which is needed in order to get into v-tec. Loosely it's like this. Normally I can hit v-tec in second no problem. Now in order to hit v-tec which should be in second I hve to shift into third to compensate for the rpm. Does this make sense??? and if so can anybody help me with this problem??? Thankyou

No, it doesn't really make any sense, sorry.

VTEC transition happens at 6000rpm. Doesn't matter what gear you're in, or what speed you're traveling at.

(The only things I've heard of effecting the VTEC engagement point are high altitude and low oil level.)

Do you mean in high rpm, the rpm goes up harder? bcoz the vtec kicks in 6000 no matter the speed or gear like Elistan said!

Sorry I wasn't quite sure how to word it so I will try it this way. When I get up to around 4000rpm in any gear it sounds like I am actually at 6000rpm, so when I try to get into v-tec I have to shift gears because my car sounds like it is at 8000rpm before it even hits 6000rpm I hope that is worded better.

My guess is that the problem is with your ears, not the car. Try some earplugs, perhaps? Shift at 9000rpm and you'll be fine.

You should learn to drive by "tach" before you try to drive by "ear".

I'm not sure if I fully agree with you on that one. My first car was an '00 Civic without a tachometre. Listening to the engine was the best way for me to be able to tell when I should be changing gears.

To be fair though, we do have a tach. in this car, and if you aren't familiar with what the engine sounds like at different rev ranges, then you should definitely rely on the tach reading.

^ My reply was based on the fact that he is in an S2000. Obviously, if you don't have a tach, you can't drive by it.

I have been driving my car for three years and i am pretty sure I know what my engine is suppost to and not suppost to sound like and I know there is a problem. I didn't post this so there could be arguments about it. I posted it because i need some help andI thought this was the place to get it but it looks like I am wrong so I am sorry to waste everybody's time. Thanks for the help. Chow!
