Hey all,

need help. Tried installing a HKS SSQV to the rb20 in an AUTO where the mount for the stock BOV is located. Blocked off the return hose and connected all lthe necessary hoses. But when it came to driving (read:crusing) it jsut stalled when ever the revs were changed below 3,000rpm. You could jsut hear the BOV releasing then the engine jsut shuts off.

The seller off SAU tried resetting the ECU via Disconneting the battery and all but the stalling continued. ALl means were considered but need more info and help.

Any tips be great cheers all!!

Err I'm not sure how a BOV is suppose to work on an auto but with a manaul it lets off when you let off the gas, i.e when throttle body is closing.

So hows it suppose to let off if you just keep your foot on the accelerator? Maybe that has something to do with it.

You might want to try and adjust the spring tension on the valve so it opens easier under low rpm, BOV's on autos can regularly cause stalling if not adjusted properly

Just keep adjusting it and rev it to 3000rpm and if it goes back to idle without stalling or struggling it should be fine

What boost you running?

Sorry to hijack thread but.. when you switch from a plumb back to atmo blow off valve, does it not play havoc with the air flow meter taking into account having the plumb back, with the a/f mixtures? Like mine, when i disconnect the plumb back hose the idle is really rough... stalling occasionally..

Makes sense..

What I meant was the afm has inbuilt compensations for the air coming back through the plumback, when you take the plumback away the mixtures aren't right because of those compensations..

So yeh - the electronic means to fix that would probably have something to do with that... right?

Tnanks for the helpful advice, reckon gettin the HKS EIDS is teh way. But my mate is running an atmo BOV on his auto, retaining the stock BOV, and using the cooling pipe near the Air Box. Is this a simple soluyion or will it have a future effect?!?!

cheers all

      I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.

      Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.

      Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them?

      I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.

      Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
