i just got a vtec controller (not vafc) but havent hooked it up yet. im tuned on crome and have my vtec at 5300 and i shift at 8300. i wanna take my car to the track on wednesday. how low should i go to get the quikest et? everyones sayin 4500 but dont you want your vtec to just engage each time you shift instead of already bein in vtec?

 

It depends on your engine (mods) and tune. It should engage where it benefits performance most. Get some dyno time.

 

Ditch the vtec controller!

 

 

VTEC engagement points should have been set by a good tuner to smooth out the power curve. Faster ETs is dependent on many other factors such as traction, transmission gearing, and how good the driver is. Power is nothing if the car and/or driver fails to harness it.

 

well i got it for free and i like how it says my exact rpms and has a shift light plus id like to set my vtec up when im on the highway cuz my car is at 4500 rpms goin 80mph in 5th gear. its not a afc.

 

it was set at 5300 by my tuner but im up for a fresh tune anyways since ive done a few mods since then.

 

But it doesn't benefit anything. If your Vtec is at 5300rpm then there is no need to worry cruising at 4500rpm. I myself have a b16 tranny cruising at 4500rpm going 80mph. I however just choose to cross off low load vtec engagement on NepTune. So even if I hit 5500rpm at light loads Vtec does not activate.


I myself had a Vtec controller when I first bought my car. After taking it out, my car ran alot smoother.

 

well i wanna set my vtec to 4500. is that too low? can i cross off low load vtec engagement on crome?

 

Why do you want to set vtec at 4500rpm? It's not like your going to feel any difference being in vtec on the freeway at low load anyways. I don't know if it is featured on Crome or Crome pro. I just know NepTune features it.

Again to indicate the best vtec engagement, you need to strap it to a dyno.

 

I can almost guarantee that amy movement of the VTEC engagement higher or lower than the optimal setting(set by the tuner) would yield slower ETs.

 

i had mine set at 5300 tuned on chrome&dynoed..not to bad..I/H/E
