Help! My Stagey stalls.

[burkey22]

Hello.

I just got my Stagea last week and I'm rapt with it. I've put a turbo back 3" exhaust on, an Apexi Power Intake and a GFB BOV. I just installed an RSM today.

I have a weird problem. It seems that when I put the foot down and then come to a complete stop the engine will die. It happened twice today when I pulled out of a carpark put the foot down to go up a hill then stop at the top for a roundabout. It's an auto. Has anyone else experienced this? Why is it so? My car has only done 34000ks.

Please help.

Thanks.

Zane.

Hi Zane, you can't have a open to atmosphere BOV. The ECU knows how much air goes into the engine via the AFM, so it squirts in the right amount of fuel for that air. But the BOV lets a whole pile of that air escape, so the ECU squirts in too much fuel when the BOV is open. Bingo, too rich a mixture and the engine stalls. Get a plumb back BOV and all will be well again. I have never found anything wrong with the standard BOV, so I have and will not be changing it on my Stagea.

Hope that helps:cheers:

I had a feeling that may have been what it was. If I buy an SAFC-2 that should fix my problems yeah?

Thanks for the help

My BOV is a Hybrid valve. If I turn it further towards plumb back this should fix it aswell?

Also the other day when it stalled I put it into P so I could start it again but my car was still rolling a bit. It started making this shocking noise. Kinda like when you do your diff. I stopped and put it back into D and it went O.K. Would I have done any major damage? Feckin' hope not.

Nope, the SAFC has no ability to adjust zero throttle richness.

Yep around 60% or more plumb back will help, assuming it is physically plumbed back of couse.

Oooops, auto gearboxes have a lock on the output shaft so that when you put them into Park the car doesn't roll. Hopefully you didn't break off the locking pin. Easy to check, just put it in Park on hill, when you are stopped of course, and make sure it doesn't roll.

When moving, Neutral is the place to restart the engine.

Thanks for your help mate. My mechanic just told me the same thing. I have just had a boost gauge installed. I noticed that boost is around 5psi then goes up to 10psi at around 4500 revs for a little while then it drops back to 5psi until redline. Is this normal?

I think the SAFC II model has the feature to adjust the fuelling mix as it returns to idle. This is to stop the overfueling that happens and stablize the idle. The earlier editions didn't have this feature. It must have been a feature added purely for the addition of externally venting BOV's.

The problem was the tension on my spring was wound as loose at it would go. I just tightened it up abit and hey presto. Fixed.
