After I got my BOV fitted, the car stalls.

Now I've heard of this happening before, and people saying to tighten up the BOV.

But I have a GFB Mach 1, and I don't know how to tighten it?

Does anyone else have one??

JIMIH..

With a external venting bov like the one that you got, it will stall no matter what you do.

If you tighten it a bit, it might stall less, but it will still stall or almost stall after it blows off due to the whole air flow meter issue.

To Tighten the GFB Mach 1, there is a screw on top. If you turn it clockwise, it will tighten it and push the piston a little lower so that it is completely closed during idle.

But your car will probably still stall in a situation like slowing down to a set of traffic lights or something.

If you are in sydney, and you want help then let me know..

I can help tighten it or whatever...

I've got a plumb back GFB bov on my car. It's briliant. No stalling, heaps better response when accelerating.. and a nice muffled khhhhhhh type sound through the pod filter during gear changes.

If you can still return it, and you want the psshhhtt sound, then see if you can excahange (with money on top) for a Hybrid BOV..

this way you will get the sound and no stalling.

cheers for that :)

i'm in Perth but I tightened it and it doesnt do it as much now ... I can sort of keep the revs up a little as I'm slowing down to the lights to keep it from stalling.

It's not as bad as it sounds, but it's just a little annoying sometimes ie. if you stall it in front of a group of people :)

My car used to stall too... It may be the BOV or bad tuning(e.g. air/fuel ratio,do u have a SAFC??)..

Anyway my POINT is it is REALLY DANGEROUS.... My car stalled once when it was raining and my car spinned 180 and skidded some distance and nearly hit another car...Imagine if it hit a passerby.... Lucky me!!!

I suggest u either solve the prob or change the BOV..... :cool:

I've heard that 'lines are very sensitive to externally venting BOV's so I got one of those GFB hybrids that plumbs back some air and vents the rest. Works awesome even with light spring pressure and it has never stalled, plus it's not too ricey. In fact the car runs better than with the factory valve, I think it must've been leaking or something

From memory I think one of the features of the SAFC is to allow for an atmo venting BOV.

Yeah here is the quote from the Apexi USA website:

" On hot-wire vehicles, the Deceleration Air Flow Correction function is capable of curing the erratic idle and stall problems associated with open-atmosphere blow-off valves on hot-wire air-flow meter systems."

Taken from here:

So don't keep stalling, invest in a SAFC today. I'd also assume the PowerFC can do this as well but I've never looked into it....

I tried setting that but it does nothing!

i used to have problems with my car stalling... however it was due to the afm. Its rather "exciting" when the car stalls infront of incoming traffic in an 80 zone...especially when you needed a new battery as well and when you tried to restart the car it would not crank over!!////:dump:

and that would achieve?????

when i set mine it seemed to work, the the problem is when u start the car cold the next day the idle gets all screwed up!

      You could try some less aggressive pads on the rear. I found (a long time ago when all my brakes were stock 32) that using the same (Bendix Ultimate) pads at both ends made the rear bias excessive. I strongly suspect that the stock Nissan pads probably use a different material, but aftermarket pads will usually be the same material regardless of what pad they are put onto. That bias situation did get better when I put R33 calipers on the front AND used the same pads - just transferred them from old to new calipers. So you should feel the difference with the change you're making. But certainly do not forget the option to change the rear pads down a grade or two.

      Misfire/stalling issues

      Ha ha, sorry dose, I wasn't meaning to argue the point on "it'll do f**k all". I was only shining a bit of a light in the flawed logic you used with it mate.   I 100% agree that there is zero point changing stock manifold with a stock turbo, unless the manifold is f**ked. And only reason I'd ponder aftermarket manifold on a stock turbo would be that I'm too scared too look at the potential ludicrous prices people are asking for a stock manifold! Ha ha ha

      Can someone tell me what this part is for? Someone duct taped it.

      Shhh... Muricans don't understand the idea of metric so can't find half the stuff we have for modifying JDM cars 😛

      Your response is extremely similar to what someone on the Haltech tuning tips Facebook page answered me. I take it you're also on there haha. Dyno is booked for June 27th and that's exactly what I'll be doing. I also realized I never setup a pulse width adder table so I went and did that last night. Made a fair bit of fueling difference in low load areas.  I sorted out my power steering belt woes. It was an alignment issue and it has now survived multiple instances of abuse that would have killed it prior. I also changed my fuel pump hose. The hose I replaced looks nothing like the legit gates hose I received. Real hose is actually 5/16" and is labelled properly. Amazon refunded me but has been giving me grief about my nasty review I'm trying to leave... I keep having to modify it for acceptance. I want to make sure the point gets across to others.  Last issue I want to deal with soon is the slight vibration I get in my steering wheel with my GKTech Spacers in front. My annoyance has grown and I'm at a point where I want it resolved. I've tried everything I can come up with like clean spacers thoroughly, tighten in star pattern, retorque, have wheels rebalanced 4-5x with a variety of machines (2x with a Hunter elite). I've also taken the spacers off and remounted multiple times just in case.  I'm starting to think my GKtech spacers are at fault. I'll pop a wheel off and toss a dial indicator on tomorrow to verify runout and parallelism.
