Question for you guys and gals.

I just got my AP1 the other night, and i ran it to redline today on the way to work ( temp gauge had 3 lights). I didn't really feel the vtec kick in like I did with my civic.

So when is it suppose to change over on an AP1 (7k?) and does it hit hard? Would it throw a code if it doesn't switch over? My SOTP meter could be off seeing as how I have drive muscle for 3yrs.

Just wondering.

Thanks!

 

vtec engagement in each car varies. the ecu is very sensative to the enviorment.

some may kick in as early as 5,200rpm and others may kick in later around the 7's.

 

Mine kicks in 6k RPM.

I know what your talking about though. I realiized that on stock Ap1's, you can't really hear the VTEC cross over, but you can feel it pull you back though to the seat.

On my B16 power Del Sol Eg2 and my girls Si, The VTEC cross over is amazingly loud! Damn I miss that fwd

 

@ 6,000 rpm the s2 v-tech kicks in

mine goes up to 2.8Ghz with the antenna booster

 

VTEC isn't some like afterburner turning on. Did you feel the car going faster? If so, then it turned on.

 

I just doesn't seem to hit as hard as my civic did. It may be changing over and my SOTP meter is busted because of driving the 'stang for so long.

Maybe at lunch I will go for a ride and try it again.

Would it throw a code or miss if it doesn't switch over?

 

If you were not engaging VTEC your car would struggle to pull to into redline.

 

an s2k is a very differnt car then a civic... just becuase you did this or that or felt this and that with a civic doesn't mean you'll get the same in the S....

It may not hit as hard as your Civic did. The S will get louder at VTEC, but not some insane amount.

Like someone posted, the S will struggle to get to 9k without VTEC engaging.

Vtec Engages smoothly on the S2K not like some of the other B/H series engines

The A/F is a big reason, When tuning a Map you can make Vtec engage harder by what the A/F is at that moment

 

Sounds good. It certainly doesn't struggle to get to 9k.

Thanks for the replies.

It has nothing to do with the air fuel ratio. The cam profiles on the primary and vtec lobes determine vtec transition.

yes sir that is soooooo true.....

if u want it to "kick in" take off the top cover to your air box.. then run it you'll hear it for sure!

 

I just drove a stock S2k today for the first time in a while. Yeah, there is no audible VTEC crossover.

Vtec kicks in at 6K on the AP1. If your running the stock air box then you won't really hear, or even feel it that much. Throw an aftermarket intake on her and you'll definately know when your in vtec

 

I tried it again and I notice it kicked in about 6k. Just wasn't as aggressive as my civic (atleast it seems so) but then again my civic had quite of bit of work done to it and this car is stock

Thanks again for the help.

 

I know I'm stealin this from somebody but it's too good not to use with that Post.

 

VTEC should kick in at 6200 rpms. don't really think climate has much to do with it...

my VTAK blows off...whatchu know about dat?

 

I just wanted to put my two cent in, On stock honda you should not feel Vtec "kick" in it should be nice change over if the car is tuned right, the S2000 is one of Honda Top tuned cars and your not going to feel it kick in Hard. Unless you start mods but even then you want it to be a nice change over with good tuning.

 

She doesn't kick, be she sure does jump.
