hello all, now i admit i am new to cars and turbos and stuff and probably dont know wat im on about, but i havea hks ssbov and everywhere i go people seem to be bad mouthing it becuase it apparently makes ur car stall and shit like that.

now i went through those problems as well, but i later found that wen having a hks ssbov u are also required to have a hks idle stabaliser, and wen i got that in, everything worked like a charm!!!!!!!!!!!!!!!!!!!!!!!

Flutter is not from the BOV it is from the air flowing back through the turbo. It's not good for the turbo at all. Obviously by over-tightening the BOV you're gonna end up with the air going thru the turbo as it can't vent, hence the flutter.

One of the things about Jap BOV's is that unlike ones from Oz they aren't all simply products of the metal laythe....A lot of Jap ones are actually cast items, this is why they are far more expensive. From memory the HKS Sequencial BOV is not adjustable, I had one a long time ago on my starlet. The Super Sequencial is though.....then of course there is the Super Racing BOV from HKS, now that's expensive :)

As I said I don't think you can adjust the older one. If yours has adjustment then what it does is put more pre-load on the actualto spring insied the bov and makes it hard to force open, you do this if you run higher boost (set it soft for low boost cars and hard for cars with much higher boost) The basic rule of thumb is set it hard so you hear the flutter then back it off till you can't here it any more ..... that should be the right setting.

because the SSQV as 2 valves, the smaller purple pointy thingy and the bigger valve with the HKS wordings...the screw only adjusts the tightness of the big valve.

i've yet to solve the damn fluttering problem because of this...no matter how loose i turn it.....it only affects the bigger valve...

    • Have you done the Ignition Sync Wizard in the AEM software?
    • Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...
    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
