When I bought my car it also had an atmo bov and never stalled once on me, never ran boggy, never had issues.

How many tanks of fuel have you run? Moisture/ shitty fuel will cause your problems

[Travis32]

i havent ran any full tanks bout half a tank plus atm

[75coupe]

do you really need the sard fuel reg?

do you have a std one as a tester?

is it an authentic sard?

[c210rick]

First thing i would do is change the fuel pressure reg back to a standard one and see how it runs then.

[SargeRX8]

Get that regulator off it seems like its causing you more issues if anything and probably unnecessary. Ive got good horse at the wheels and the standard is perfectly fine. Ive got a Nismo FPR just incase.

[GTRsean]

Yep, you may as well get a stock rail and fpr, and then check fuel pressure again.

The sard was genuine by the way...

[The Mafia]

You can bandwagon all you like, but I can see the retardness all the time when I have the wideband in. Whether you think the car is running right or not.

But if you guys want to think or continue to think that adding an air leak to a AFMetered system is a wise idea, then complain about any kind of stalling, good for you. Just shows you do not understand at all. Just want noise.

Maybe buy a MAP sensored ECU so you can blow off your load all you want.

It all physics, and in plain black and white - ATMO BOV + AFM = Wrong, never meant to happen.

[75coupe]

yep I agree ^^^ but other tuners have said you can tune around it if the bov is decent (doesnt leak when its not suppose too) and consistent.

[The Mafia]

There is nothing to tune around, other than "fudging a few figures". But it can never be fixed. - And, I hope you do realize that a BOV that doesn't leak, is one that is welded shut, or recirculating back?

The second the BOV opens to make the big "whhhooosshh" its leaking? Can you not see that? How can that be not obvious?????

Also, when your BOV is tight, its not doing anything, other than creating reversion... you know... tututututut.......

All these problems... for a noise.... amazing

[75coupe]

Yes I realise when its open the system is leaking, yes yes...

Im not into the sound, its just the fact that I dont want a crap rubber hose going from side of the engine bay to the other (forward facing plenum)

and I cant yet justify getting a nice metal pipe fab'ed up just yet... yet

seriously though cars can run fine with an atmo, I have hardly any knock, Im not too worried about reversion as its only on low pressures this happens with mine, otherwise its a straight release no tut sound.

Just everytime someone says atmo you immediately jump down their neck about it, its definitely your 'pet hate', get over it...

you have good knowledge, why not help out the OP and then 'IF' everything points to the problem being the atmo sure suggest they remove it...

verbally abusing people for it aint the way too go...

[The Mafia]

I have already helped the OP by stating that the SARD is junk. He even answered his own question.

I've seen so many of them exhibit this exact symptoms, and make the car useless to tune.

Hence now, if I pop the bonnet and see a sard or malpassi, I tell them not to come back until I see a nismo or factory one attached.

You've made 2 changes, and now the engine doesn't run right. Well then, the obvious thing to do is go back to the point where the engine ran without any problems, and change just one. If the engine still runs fine, then it has to be the second change that is causing the current problem. Otherwise its the first change that is causing the current problem.

It's not rocket science.

Mr Mafia you seem adament that an atmo BOV on a GTR will 100%, without doubt, put ya house on it cause a rich condition on decel because you are so Knowledgable and a specialist "tuner" but do even know that a GTR shuts the injectors OFF on decel? So your entire thesis/theory on OEM GTR BOVs is how does one say ..... Horse shit!!!!! Hmmmmmm....... And as for SARD fpr's the only times ive ever seen them give trouble is when 1 has been fitted incorrectly or was 1 of the chinese copies that have diaphram issues.... What is your background? ie: where did you learn to tune? Do you have a workshop or do you work as a tuner for a shop? Now to the orig poster i had this excact same issue with my R33 GTR and it turned out to be 1 of the AFMs was shagged. Replaced them both and problem went away. If you can borrow a pair of known good AFMs to try do it asap and save your hair. PS make sure you have the fuel lines going into the correct ports of the fpr, they cannot go either way. Erratic fuel pressure is a major cause of concern imo. Cheers. N if i was you id just ignore Mafia seems like he got a laptop for xmas and now with a few cables he's a "tuner" ...I dont know why he gets so jacked up over something so trivial but im guessing it was because he knew something that nobody else did!!!!

i been thinkin fuel reg since it started thing is i thought id rule everything out b4 i had to start spending money.

i dont have the standard reg or rail anymore so cant really go back

mafia says fuel reg so im gonna try a mates one tonight see how it goes n to make him happy im gonna take the bov off.He knows his shit but just the way he talks to ppl i dunno how he has any customers.

also thanks to those who dont talk to ppl like theyre a peice of shit
