is it the same as engaging, 5700rpm, or different?

 

5400?

 

 

Anyone know why honda decided to turn it off at a lower RPM?

 

I thought it was 5500...Does your vafc say 5400 neomugen?

 

To keep emissions down is my guess.

 

If it switches down to the primary lobes later, it's not for emissions. You want to switch back down to the primaries earlier for emissions. It's probably to keep the car within it's powerband between shifts.

 

The GSR could benefit from a little lower disengagement for sure.

 

who fucked up the title?? =/

 

I saw that too..

 

I don't know who changed the title in the first place, but I changed it back since it was making my head hurt.

 

Yeah what the hell who did that.

 

Well you can't have it disengage at the same rpm because what is the car gonna do when it hits X Rpm? Disengage and engage at the same time? If you disengage it higher than the engagement point, you have more of a chance to fall out of the power band. Either way, i don't think +/- 100 rpm is going to make a difference that is noticeable.

 

That's how my VAFC reads at stock settings.

I only know a rule of not setting the disengage more than 400 rpm than engagment. The car will act real tard.

the vtec light on my vtec controller shows mine doesnt dis-engage to near on 4000-4100rpm

 

its 5600 stock ecu setting.

 

So VTEC engage at 5700 and disengage at 5600? That doesn't sound right. The rule of thumb is 300 rpm in-between the the low-hi, high-low.

 

i would figure that the point of it being lower is that once you hit it, if you are just erratically blipping the throttle around that point, it doesn't constantly go in and out of VTEC

 

I think this is right. I'm pretty sure it's 5400, if I remember correctly.

 

.... not quite.

5600 - off

5900 - on.

 

FWIW, when I installed my VAFC on my GS-R last year (when I had it), the factory settings were 4400 engagement, 4300 disengage. When I upped the crossover to 4900, I set the disengagement to 4800. So I am assuming the R disengages at 5600 (100 rpm under the engagement).
