WAS WONDERING IF IT IS WORTH IT AND WILL MESSING WITH THE VTEC POINT MESS WITH MY MOTOR WITH OUT GETTIN IT TUNED

 

Completely lame.

Changing your crossover without propper tuning and modifications makes you lose power, and the spoon vtec controll is:

A) way to expensive
B) has ZERO options
C) is only cool because it fits into the stock switch plate jack.
D) Please stop typing in all caps.

 

Not worth it.

He's right, escpecially on option "D'.

 

I'll sell you a VAFC-II for half the price.

 

actually just to be the devils advocate here changing the vtec crossover point is pretty important when tuning a vehicle that warrants it, such a built motor with boost, my vtec crossover point made most power at 4300 with a built and boost d16. But as for you needing it i doubt it highly

What isn't to understand. It's clear and to the point...

Exactly, hell in some cars the crossover point might even been moved higher up in the RPM band. It all depends on the motor, build, and where it benefits the most.

 

Yep, but the people that usually use a the VTEC Indiglo Clock II have stock sohc vtec motors lol.

 

well i wanted to kno cus i found one for a very good price and i want to put my vtec point to stcok as it kicks in at like 6000.

Yes you are correct. Changing the VTEC crossover point is very important. For example, when you change the intake manifold ona GSR from the stock type to a single plane design such as the ITR style, you better believe you need to change the VTEC crossover point. I raised mine about 1,200rpm, which was found to be the optimal point. HOWEVER, just changing the VTEC crossover point without changing fuel and ignition parameters isn't going to help the matter as you will still be running the stock maps.

Spoon Sports uses their tuned ECU in their endurance cars which are more aggressively fueled and timed then a stock ECU obviously. Their VTEC controller is strictly for use on different circuits as they are more concerned with changing VTEC limits based on speed and gearing, as opposed to fine tuning a smooth power band on a dyno.

Lets be honest, anyone who gets their car dyno tuned, once the optimal VTEC crossover point is found, why would you change it? Exactly.

Haha, yes.

At OP:
Depends, what's your setpu? Are you running, like Eran said, a stock motor (any kind...doesn't matter, if it's stock, don't touch the VTEC point)...or are you running a fully built ITR Turbo setup? Somehow I think the answer to that lies in the creation of this post.

Though if by some farout chance you're running some nice azz setup, then it might be worth changing the VTEC point (not just picking a number out of a hat...with proper dyno tuning). What kind of setup you running, and on what chipped ECU? Or are you running stock.

Like I said, if it's stock, leave it. (BTW: I/H/E/ are still stock in my book and won't change where you'd want to change the VTEC engagement..I'm talking like a full blown skunk 2 valve train upgrade or something)

go back to the stock ecu

Wait...now I'm confused.

Are you saying that somebody altered your VTEC engagement then took whatever they altered it with, out? Reason I ask is b/c the way you worded it:

What engine with what upgrades are you running?

 

Your ninja edit skills are superior. I was about to call you out on the other bolt-ons you had listed, as I have had personal experience needing to alter the VTEC engagement point when dyno tuning an old car with every bolt on possible, before I built the spare. Then it was changed again.

i have a b18 wit a skunk 2 im and with everything else stock and for some reason the vtec dosent cross over till like 6000 or 6500 what is the normal cross over point on a gsr

 

EDIT: I'm retarded and need more sleep

4,400RPM I believe.

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Eran &raquo;</TD></TR><TR><TD CLASS="quote">6400.</TD></TR></TABLE>

soo 6400 is the stock vtec cross over on a gsr i read some where it is 4800 but not sure

 

Oh yeah........ durh, I forgot how low it was on a GSR. &lt;-self

 

stock for a gsr is 4400. says so in the helms.

oka soo if it is 4800 will a skunk 2 im make the vtec crossover jump up 1200 rpm

I'm going to take Eran's word for it that that's the stock crossover point because I have no idea what it is on a GSR though that sounds about right.

Anyway. You have a skunk 2 IM, that matters in the VTEC crossover point world. But PLEASE don't buy a VAFC and start blindly changing crossover points. If you want your VTEC changed, you're going to have to buy a tuning program (such as chrome...I'm pretty sure all the market standards for honda chipping programs you can change the VTEC crossover with), chip your ECU. Then take it to a DYNO to have it changed for optimum performance. Do I think it's neccessary? Not at all. Do I think you should do it? Nope. Do I think you should definately NOT start randomly messing around with the VTEC crossover point? Definately.

You want it changed, get a chip and put it on your ECU, then get it tuned professionally on a dyno. I'd trust a dyno tune for VTEC crossover points more than a street tune.

Though if you're just running a GSR with a skunk 2 IM, it's obviously not a race car, so you'll be fine just leaving it the way it is. I wouldn't worry about it. You shouldn't either. If you want to get it changed, pay the $, get it done right.
