The ECU decides when to engage vtec based on a number of things, and the point will not be the same every time.
things like temperature make a difference

mine is about 6000 .. +/- 200rpm
the cams are optimized for certain speed range, so even if you can set them to activate at a lower speed, it wont be as effective

lowering vtec is the one of the single best ways to improve you midrange power as well. with my vtec set at 5400 my whp from 5k-7k jump by 14rwhp!

can you change the vtec engagement point w/o adding fuel (via VAFC for example)? if you change the vtec point does the stock ecu add necessary fuel to take advantage of it?

[QUOTE=bruisedthumb,Feb 4 2007, 11:24 AM]I am all confused (duh and not uncommon) after reading way too many posts on this topic... Anyone know when the VTEC is supposed to kick in for the AP2?

I thought the iVTEC system was improved upon the original VTEC so that the power was more spread across the power band? Like different cam lobes are activated at different speeds/rpms to create more linear power?

ah ok...thanks for the clarification =)
any idea why they ddin't equip the S with iVTEC? especially in the ap2's they wanted to make it more streetable....iVTEC would have pushed more of the power towrads the low end...

I think ivtec was developed or at least implemented after the F22c was designed. They didn't want to mess with it much.. the head in the two engines (f20c/f22c) is virtually (or entirely?) identical so it would make sense financially to stick to the original design.
