What RPM are you guys activating your vtec on a boosted b16. my accel gen 7 has an output wire for the vtec activation and was wondering where i should set it. thanks H-T

 

its best done on a dyno
to make a smooth transition and max power effect to HP and TQ

 

Co-sign
Also every motor is different so it's best to find out on a dyno

 

ok thanks guys

 

5250, itr cams/IM dyno proven

 

My Vtec engagement is lower than that

 

For a turbo car...

Best way to do it is dyno the car completely on the low cam then repeat with the high cam (set VTEC as low as it will engage) then wherever the two dynos overlap should be your engagement point.

 

whats your vtec set at? dyno proven? what cams?

 

What works for me isn't going to work for you bruh
My tuner did all the work

 

bruh lol

you act like im going to lower my vtec to match yours or something, i already tuned my car for optimal vtec xover why would i want to be slower by lowering my vtecxover

 

Lowering it doesn't mean your going to be slower. When I look at my Dyno graph, I can see that my tuner set it up where I begin to build boost

 

Maybe I'll just have VTEC all the time :p

 

k thanks for the advice guys.

 

He most likely does not even know where it is set.

OP - If you have a completely stock engine and do not have a way to truly test it, it is best to just go with the factory engagement set point. You can use things like data logging and fuel maps to see where about it needs to be. Adjust it up and down by at least 200-300 RPM to have some sort of measurable difference. You are looking for the smoothest transition. You should NEVER feel VTEC engage. The butt Dyno almost always lies to you.

 

I know where mine is set at, I just refuse to say where it is

 

 

Shhhhh it's a secret he doesn't want you to steal his secret vtec point....

 

co-sign

but it really doesnt matter until you hit the dyno and find the sweet spot

 

What is this "co-sign" crap I always see? Nobody is applying for a loan. Obviously your engagement is stupidly low and you don't want to be "stoned to death" over it. Engagement point doesn't even do much but shift the power band around. Your top WHP numbers will still come out to be the same either way. It absolutely does not have to be set on a Dyno, but is easiest to SEE on a Dyno.

 

An example. my older, urban slang-deprivedindividual

1. (In the positive) - to propound; to sanctify; to advocate the genuineness/veracity of another's character.

Example. "Who's the dude you came in with?"
"Oh, that's Dunny. Don't worry, man. I co-sign for him. He's cool."


2. (In the negative) - A.)To acknowledge and accept partial responsibility for the presence/actions of another person and the effects thereof, or
B.) To deny all responsibility and/or attachment to said individual and/or their actions and any effects thereof.
(positive scenario - your friend's party)

Example - (negative scenario - some random party)
"I think your buddy's about to get his *** beat."
"Who said he's my buddy? I just walked in next to him, I didn't co-sign for him."

 

Now that IS interesting. No matter how much I try to keep with the times, I always seem to fall behind. Thanks as usual "TheShodan".

 

Lol

Co-sign = agree

 

Weve tried that in our accord. It wasnt very happy after 5-10 minutes of running. lol my advice is to stay away from that. Haha

 

VTEC killers with ferrea rollers
Maybe... I still want to see what the GSC T1s can do with a gt30r

 

In the "urban" community its a little deeper than simply "I agree", but yes it means that too.

Example: At the 0:34 mark
