Atmo BOVs on Skylines can be a bad mix. You can fix it up, DAFS.

lach 32 Posted July 27, 2007 Share Posted July 27, 2007 happens to most people who install the atmosphere venting bov's. After a while you will learn how to adjust your driving so it doesn't stall. All i do is blip the throtle when coming to a stop ect. Do a search on the forum about this, been covered alot of times, you may find some use full tips.

LatinR33 Posted July 28, 2007 Share Posted July 28, 2007 Unfortunately blow off valves and skylines as some other member explained are not a good mix. I even use to have a GFB stealth that you get to adjust how much air is vented and how much is kept and car still didnt feel the same and idle was terrible. I know its not what you want to hear but if you want to have a car that runs well then install your stock bov.

clkngezz Posted July 28, 2007 Share Posted July 28, 2007 i still have my stock plumback on my s1, no problems as in running, sometimes when letting clutch out a little to move forward in places like drive through with a little bit of throttle then go to put brakr on and clutch in cars idle does drop to close to a stall but then picks up again, only problem i have in regards to stalling hope this helps Link to comment https://www.sau.com.au/forums/topic/178380-problems-after-installing-a-bov/#findComment-3255122 Share on other sites More sharing options...
adam-__- Posted July 28, 2007 Share Posted July 28, 2007 Stalling when having a atmo bov installed is a really common thing. The reason it happens is because the afm detects the air going into the engine and puts more fuel in to burn the air, but the air is not getting into the combustion chamber, it's going out of the bov. I hope that made some sense. As far as I know, it's something you just have to deal with if you're got a bov installed.

Rob_C110GTR Posted July 28, 2007 Share Posted July 28, 2007 some people here adjust the idle just a little higher than stock, others just learn how to drive them like when you're about to stop change gear or clutch in when the idle is near idle speed. Or you rev it a little before you stop. Link to comment https://www.sau.com.au/forums/topic/178380-problems-after-installing-a-bov/#findComment-3255395 Share on other sites More sharing options...

FordyR31 Posted August 11, 2007 Share Posted August 11, 2007 (edited) The main issue with atmospheric BOV's is the AFM... Once air has gone past that it is accounted for by the computer, any difference an atmospheric BOV will cause means there is air accounted for, but not being used. With MAP sensor its a different story as it reads manifold pressures not airflow before the turbo. With the plumb back system the air goes back through the turbo or the afm keeping it all in the circuit of the airflow so the ecu can adjust according to the afm readings. Some cars just handle it better than others, my mates 32 used to be perfectly fine with big turbosmart BOV's but my mates 33 would stall all the time with a Blitz one and then the HKS one.

Green_s13 Posted August 13, 2007 Share Posted August 13, 2007 it is odd i have never had a problem with mine, it is possible that your BOV is not adjusted properly.

adam-__- Posted August 14, 2007 Share Posted August 14, 2007 it is odd i have never had a problem with mine, it is possible that your BOV is not adjusted properly. Maybe you have an aftermarket ecu to handle the loss of air from the bov?
