So i have the dejon upper IC piping with the HKS BOV not recirculated cause i didnt get the part yet. DAMN EBAY!!! so sometimes after i rip it in third to about 5000 rpm throw it in 4th and just let it coast and it pops really really loud about 5 or 6 times and when i come to a stop the idle is rough and the vacuum is at about 15 or 16. is it running lean or rich? oor is this because im not recirculated yet? i also get a p013a code A/F reading sometimes. ANY IDEAS?? PLEASE HELP!!

 

wow.. Yet another guy running a bov having issues. Let the trend continue.....................

 

^Jumping to conclusions is how these BS rumors get started Ive personally tuned 3 cars with VTA BOV's on them without ANY issues at all! Shez is one of them... So stop spreading BS without knowing the facts.


Is this a stock tune car??

 

thanks BYT. you cant jump to conclusions especially with these cars. i searched up the code on the forums and found out that the trend is actually throwing the p013a code with the ZZPerformance downpipe. A few people said that it could be a bad sensor. One guy said that he unscrewed it and water poured out of the bung. I also removed the vacuum tank and ever since then, sometimes between shifts the revs drop really slow. im thinking about putting the vacuum tank back and see how it runs thens.

 

I have the ZZP DP and have never seen that code yet.

 

Dude... it's because of the BOV... seriously... you and I both know it's because of it... going stupid rich after a shift....

 

God I hope that is sarcasm...

 

It might be this

 

Dude no one is jumping to conclusions..

He obviously had no issues prior to his bov install (or he would have made a post about ongoing issues), and now poof, he suddenly had issues.. hmmm..

Obviously you know your **** bro, no one is taking that from you, but it doesn't look like bs to me

 

Do you have the stock tune or aftermarket tune. Also that vacuum tank mod has caused some issue for people so that could be suspicious too.....

 

this doesn't sound very funny to me at all.

 

Im just saying that just because he has a BOV doesnt mean that's the issue, let's hear the whole story And then I stated tuning a few to prove that they CAN work and work well.

 

yeah BRO LIKE OMG he dont know his **** Bro..

 

lol wow.. because I said the work bro suddenly I'm a valley girl.. I love it.. ******** have a tenancy twist and misconstrue things like that. Thanks BRO

 

Im not your Bro, Guy!!

 

lol... I love it.

note taken.. BYT is apparently not my bro but I am his Guy

 

ok so everything is fixed. so everybody doesnt go crazy and think nobody knows what they are talking about. its not actually the BOV that was making the car run bad. it was a bad EVAP purge solonoid. i got the code around the same time i put im IC piping and BOV. i got the solonoid changed a few days ago and the car runs fine now no CEL's no bogging no weird idle no nothing. the mechanic also found the o2 sensor code and he ordered me a new o2 sensor under warranty so ill see what happens with that. but in conclusion it was NOT the bov

 

whats up bro's, I have an HKS BOV on Dejon IC pipes and my ***** running mint. so

What it sounds to me, is you have a leak in your charge pipes or your BOV isnt closing all the way. I have a recirc fitting on my dejon intake and if i remove that fitting and let air in after the MAF the car starts to bog real bad, as expected. Im thinking after it blows off, the BOV isnt closing and letting air in after the MAF causing it to go into that bogging mode, then when it goes away maybe the BOV closes completely. If you think about it after it blows off at real high RPM's your car is requiring alot of vacuum pressure, and if your BOV isnt closing quickly and is left open for a second it would take in alot of post MAF air for a minute causing it to bog, then the BOV seals up and it goes away. Id take your BOV off, and look at it, see if you can oil it or something, or change the piston out on it. Could be a possible solution. Maybe check your charge pipes as well to see if theres an issue there. Do you have the rubber O-ring installed under your HKS? Is your HKS completely sealed in the flange?

I used to have a Greddy RS and the only problems I had with my car at the time, which i cant trace to the BOV or the tune, is my O2 sensors went bad, which seems to be a common problem with tuned cars. and my High pressure fuel pump failed, which i dont know what caused that, i think thats just a manufactures defect and a shitty pump. But i was running a BOV vented for a long time and thats what happened.

 

yea i see what your saying. i triple checked everything when i put it on. the only thing that was a pain in the ass was the c clip from HKS cause i didnt have the special tool but i got it in with the rubber seal. ive actually no lift shifted a few times and it didnt bog out which i was really surprised about but if im just cruised and shift and put it in the next gear and give it a little gas it kinda bogs but nothing crazy. im still waiting for my recirculation fitting to come in. stupid ebay lol. but the reason it was idling weird and stuff was cause of the evap purge solonoid but i got that fixed recently and no more CEL's and the car runs fine ever since then if i have anymore problems ill let you know you could probably step me through what you did.


it did

 

i 2 have hks bov welded on my dejon charge pipes. my car runs now 100% perfect now that vince tuned it. took a few tries to get perfect.

if your running your bov in the original place of the maf sensor you are going to have a rich spike everytime your bov opens. so ive heard.

i relocated my maf to the dejon chargepipes. car runs like stock.

 

I have a Tial Q, but vince is still working the kinks out of the tune. (I am in afghanistan so a friend is tuning it for me) Your Vac is low because you are running a low PSI spring in the BOV. Go for atleast a 10 PSI spring and the vac will be better off. This may help you out in the future.

 

I still stand by what I said, and NLS has nothing to do with the BOV, it has to do with timing and keeping the throttle body open I believe. Doesnt actually keep blow off valves closed or anything, as then the air would just go back through to the turbo and thats bad. I still say to check the piston, oil/grease as necessary. also check your vacuum source for your BOV, try giving it more vacuum by T'ing into your intake manifold line

 

You are correct, NLS controls the throttle position only, the BOV only reacts to changes in boost to stop a surge that can occurr without the BOV working.
