I know some of you guys have had toda Bs so maybe you could help me. Just got my B's installed yesterday and got my car back today. My problem is that when i'm at a stop light my car idles REALLY low....First it will be 900, then it will drop to 500, then sometimes at 250, then it goes back up to like 350 and stays there. When it does that it requires me to step on the gas more before i can get going...

Some changes i have made this weekend to my GSR: Spoon JDM ITR pistons, Mugen 2ly Head Gasket, Toda Spec B, portflow inners/itr outers, skunk2 cam gears, skunk2 ti-retainers.

Low-end feels better...Is my mind playing tricks on me? Haven't tried to hit vtec yet but i know its gonna suck. Is there anyway to raise my idle? Its scaring me!

Well my installer didn't know how to install the vafc so he didn't want to try and mess something up. If anyone could help me install it that'd be cool.

Also another thing, when starting up the car and not moving anywhere, the idle is crazy! It jumps all over the place and my exhaust is vibrating like crazy.

Any help would be appreciated. I know i gotta tune this, but i gotta make some payments first before i can.

 

Do you already have a V-AFC? If not... uh oh.

 

Yeah i got a VAFC, but its just sitting in my room right now. I don't know how to install it

 

lumpy idle ownz....


hit the dyno and get that sucker tuned, i'm sure some more tech knowledgable people will chime in

 

tunning is a most with spec B

 

Its not even lumpy after i pull out of my drive way though...Its a tad bit different then stock, but i don't think anyone who rides my car will notice except me.

 

That's definitely gotta do on before anything else. Kenji (user name= kenji) sells a "plug-n-play" adaptor harness for Apex'i V-AFC... if you're not good with splicing and etc. Also, be prepare to pay ~$100 for one hour of tuning to get A:F ratio good and get your lumpy idle corrected.

IM Black R... his car was stopping in traffic too before he tuned his cams w/ V-AFC unit.

 

Hell yeah!

 

Thanks for the info, i'll im kenji right after i'm done writing this post. Will my car be ok if i just drive it around like this? I know i'm not getting the "potential" out of my cams, but i'm fully aware that i have to tune my car and get a few things before i can tune it. I need a FPR, gauge, what else do i need?

Before i do any sort of tuning, i want to fully break-in my motor. Still only put 100 miles on my new pistons.

Edit: Does anyone know how to adjust the idle? Idling at 250 makes me feel a bit uneasy, what you think?

the Vafc will fix the idle issue, install it asap.


the idle will change greatly once you dyno tune her (cams gear adj.)

 

The VAFC sure fixed my idle problem. I just lean it out by 35% at 1000rpm. My Spec B idle perfectly at 800rpm now.

 

Wow.. that much. (Or maybe that little?)

 

Now i really want to get my VAFC in.

I have a question, is it normal for my exhaust to start shaking like an earthquake when my rpm dips to 100? Cause it does and my bumper vibrates like i have the "bumps" ya know? My license plate is all going wack and stuff. When i make a complete stop my rpm dips really low, then jumps back up, why is that?

Thanks for the advice guys

 

My JUN 3's sure idle nice

To adjust you idle you need to do a couple of things. First let your engine warm up, then cross a wire to your chck plug, then unplug the iacv and then turn the screw on the top of the throttle body (atleast that is how I think you do it, dont have my manual in front of me)

 

I just turned up the fuel pressure by 2psi tonight to see how it will run. And my setting is now at -38% at 1000rpm.

 

JUN 3 = PERFECT IDLE

 

Someone told me that i'm stalling at idle because i'm not running enough fuel? Is that true? He said that since my compression is high, i need more fuel. So would a fuel pressure regulator and gauge fix this problem?

 

Not true.

You're stalling at idle b/c you have TOO MUCH fuel - you're flooding the motor with fuel and it's dying. That's why we lean out by -35% at 1k rpms - to compensate.

Basically, the cams let in more air than stockers, so the ecu adds more fuel seeing more air... well it's adding too much so it kills the motor. Listen to us. lean out by -35% at 1k on the VAFC and play with the idle screw so when you rev it up it won't die. It's easy. I call it tuning the idle.

 

Hehe...don't start that debate.

Black R: Thanks! That sorta makes sense to me. I can understand why the car would just stop if it didn't have enough fuel, but how come it would stall if it had too much fuel ya know? I mean if theres an excess amount of fuel can't it just put it aside?

Can i bring in an example and you tell me if i'm getting the right idea? So we go to a buffet for dinner, i stuff myself with food and i just fall to the ground cause i ate too much? Since the car doesn't have a mind of its own and can't control how much it "eats", it'll just die?

 

.....ok, you want an analogy?

How about normally you fart and it lights... well with spec b's the fart is stronger - so strong it blows out the fire. Get it?

Since you have higher compression, try -10 on the vafc and see how it likes it, then -20 and so on till you get to -50... if it still dies, something's wrong and you should start going +... I doubt that'll happen though... You'll prolly end up around -25 at 1k for the idle and it'll be perfect. Then you'll start on yourself for not listening to us who have BEEN THERE, DONE THAT.

I don't care what your friend says unless he's got some experience with these things. No offense, but misinformation/ disinformation is prevalent everywhere.....

IM me if you need step by step help.

 

your drowning your motor... Get the afc installed right away. you could hurt your motor.

 

Anybody in socal can help me out with this install? Or maybe i can try to install it myself but i honestly don't feel comfortable with it. I don't have a soldering gun, but i was told i could get connectors from radio shack. Is there a site or something that has a step by step installation guide for this?

 

Alright baby, after 2 hours of removing, splicing and connecting, i finally got my apexi vafc installed! I am mighty proud of myself! Anyways thats not why i'm posting.

Some of you guys said lean out my idle 35%? Does each negative point on the vafc represent a percent? And how come this thingy only goes up to 65? I set my vtec at 6500, i haven't touched my Wide throttle settings. Any help would be appreciated.

Wahoo no more vtec at 4400 *does his dance*.
