I don't know man the h22 gives a pretty significant kick when vtec kicks in.
only felt b16 and h22 but yes. I belive.
pgclee,
some people believe that a linear power curve is much better, especially for track work.
When your vtec comes in, it does not necessarily mean that you will feel a surge as you do when boost kicks in for a turbo car.
When your vtec should kick in depends on your mods also. Furthermore, if your are using toda c, I think your low end might feel sluggish. That's nothing to do with your tuning but thats the characteristics of the cams, its meant for high end.
Don't think there is one set point that all vtec engines should use. Stock vtec engagement point is the best for STOCK cars. Once you have mods, it really depends on your setup.
Kool....
this is clear enough for me now..
thank you guyz...
The secondary runners are built into the stock GSR manifold. They are vacuum operated. The ECU has no clue whether the secondaries are there or not. The one caveat is that the stock program dumps in a bunch of fuel at the RPM when the secondaries are supposed to open. Hondata or a VAFC properly tuned should be able to fix any flatspots.Quote:

dont think there is much tuning that can be had from a honda that has limited mods such as IHE..... Sure u can get a few odd kw here and there, but no means is an ecu worth its money until to start tuning beyond IHE.
Some people claim that they can tune an almost stock b series to get massive power gains.. This cannot be done unless your willing to sacrifice honda's progressive linear power to a perky one...
Oh and another thing i realise....... By getting an exhuast and maybe (doubt it) air filter you are able to feel the vtec alot better.. Not sure if it because the change over point is crazy [booooooobbaaaaaaaaaa] loud, but the high exhuast flow would work much better with the more agressive cam profile when on vtec lobes.
Just my 2 cents of BS
i once thought it odd after i started using spoon ecu that vtec suddenyl disappeared... but in fact as sp0017 said this is just because power curve is more linear... which in fact is much better... stock vtec kicks... hehehe... modded vtec screams!!!!
Does anyone drives an auto VTEC car?
How can you tell when the VTEC kicks in?
Scenario: if i am driving at 100km/h, full throttle the gas and i'll feel a kick, but not sure if the vehicle is dropping a gear or vtec kicking in.
when an auto changes gear at High speed the revs will drop, its noticeable. when vtec kicks in the engine will sound a little throatier all of the sudden, vtec change point in 4 gear is noticable eg 1000 rpmvrvrvrvrvrvvrvr5500rpmVRVRVRVRVRVRVredline.
sometimes on autos you can notice when the torque converter locks in , revs slightly drop, engine note changes. makes poeple think they got a 5 speed auto :)
I would agree totally, my mate owns a "92 jap spec Prelude and yeah you really do feel it :DQuote:

I know this might be in the wrong thread (or answered already?) but is there much difference between i-Vtec and Vtec in terms of engagement? On my Civic 06, it feels as if there's a sudden surge/kick at around 2000-3000rpm?
