I have had one of these in my car for a while now and i have not touched it vtec came in really well at 6 i tryed it at 5200 and vtec did come in so hard it was kind of slow
Whats the best point for hi and low cam?
i tryed
low - 4700
High- 5200

It's not about how hard it 'kicks' or whatever. The right way to set it is to set it to like 7000 rpm and redline the car and then set it to like 2000 rpm and redline it, and then set it at where the two power curves intersect.

with those cams my car liked a 5500 crossover...The only REAL way to know is to throw it on a dyno and play with it...But you can try this method
1. set engagement at 7000
2. Notice where the power falls off
3. Set engagement 500 rpm before that

wtf are you talking about...the low cam profile is before VTEC and the high cam profile is upon VTEC engagement...you don't "engage" the low profiles, it's what the car runs on off VTEC

are you talking about when VTEC disengages...it is PHYSICALLY IMPOSSIBLE TO ENGAGE THE LOW CAM BECAUSE FROM THE MOMENT YOU TURN THAT KEY ITS RUNNING ON THE LOW CAM...Do you understand this?? More importantly, have you seen a set of cams?? If you have you will understand what youre saying (at least the way your wording it) is completely wrong and not feasible

No actually it is possible to engage the lower cam profile, by disengaging the higher cam profile. When vtec is engaged, the higher lobe is pushing on the rocker arms and the lower lobes do not touch the rocker arms, making them 'disengaged'. You set the low rpm point for when you want vtec to disengage as RPMs drop out of vtec... and this is coming from someone who's never owned a vtec car.

lmao wouldnt that just be then when VTEC disengages???...You arent engaging the lower cam..It's what the car runs on out of VTEC...A vtec disengagement RPM plays what exactly in making power???

It doesn't necessarily have to make power to have the ability to engage, plus it does make power... it helps with low-end power vs. vtec for high-end power. If it didn't, then Honda's engines would just run on the higher vtec lobes all the time and it wouldn't have been anything special.

= / you dont know what youre talking about...but ok...Where you set your vtec "disengagement" rpm has absolutely no bearing on the dyno readout...or the 1/4 mile slip....It's where it engages that dictates the power delivery...
And last I checked....this thread was about the optimal place for it to be in order to make the most power...

dude look on the apexi website in the tech part my controller was tuned by a honda challenge professional and a apexi/toda/ems tuner.im pretty sure they know what their talking about...

Well yea it won't show on a dyno obviously but driving around in real life, not on a paper, it does. I think you're the one that doesn't know what you're talking about. I know what the OP is asking and I answered his question in the 2nd or 3rd post. I'm just trying to show you that you're wrong.
