i know,i know, except the vafc overrides the ecu and the vafc has a set vtec crossover preset which doesn't match the stock vtec crossover on my ecu,get what I am saying?
anyways i have a p30,n1 crank pulley,and i/h/e

when I dynoed my car, there was no reason to change the v-tec engagement. lets say you lower the v-tec to engage at 4,500 rpm's, but you safc may not be able to compensate fuel and you actually LOOSE power. I think a question you should be asking is "why WOULD you chande it?" like someone else allready said, if it's a stock motor the v-tec was set there for a reason.

My PYR chip changed it to like 5800 (with a 9800 redline) so I AFC-ed back down to 5500 seems to be just fine. Just remember it is a HIGH rpm cam so never go lower than stock. Unless you have a different cam and a valve train you can rev to 10 grand leave it in that area of 5200-5500.

I would stick with the stock. If you want to change it though then set it at whatever your dyno shows is best

THE INSTALLATION OF A VAFC CHANGES THE VTEC CROSSOVER AUTOMATICALLY, now i need an engagement point to set the vafc to that goes well with my ecu and engine

Re: (jwn7)
On stock cams, b16as typically like vtec anywhere from 4800 to 5500. People don't realise that everyones engines are a little different. They react differently to similar things, not dramatically different, but somewhat.
Now to figure out what point is needed for YOUR engine, you need to take the car to the dyno. Set VTEC at 3000rpm, then 7000rpm. Where the tq curves cross is where your point needs to be for the smoothest power band. Play with fuel after that.
EDIT:
I have a "mugen" p28 with vtec at 5700 and it's definitely got a little kick to it and could be dropped down a bit. Mine seems to fall on its face from about 5k up to high cam.
