So this question has probably been asked a lot and I couldn't seem to find anything on it so here goes...
I have the forge bpv for my 09 ss and it's throwing a code because the sensor is reading it going to the atmosphere.
Not sure how to fix it, only need to drop the code for emissions.
Someone suggested deleting the code right before emissions and just not using any boost until after I pass emissions and the code should stay off.
Does anyone know of a better solution to this, maybe a permanent one to drop this code.
Can't remember the code off the top of my head.

 

What the exact code your getting? Also what forge bpv do you have the recirculate or atmospheric?

 

I believe it's the atmospheric because the code is for going to atmosphere.
I'll have to use a buddy's code reader can't remember code number.

 

atmospheric bpv is pretty much a bov so a code would be common since you're not tuned for the unmetered air

 

You can't tune for that without a maf relocate. You can make a best guess to keep it from popping a code.

 

Yar as everyone said.

BPV works great. If all you want is the sound, the forge bpv does wonderful.
THe atmosphere stuff is **** until you relocate and tune for it. This is well documented and if you care about the car, either get the bpv or fix the car for bov.

 

Yup thats what i was getting at by asking my questions if its the atmospheric forge bpv then yeah you need to relocate the maf to the lower chargepipe and get tuned

 

Well here's the deal I've been in contact with my tuner can't get it done for a few weeks but I also have a cat code but that's just because I'm running no cats. Now he can delete both those codes with the tune but my friend told me you can't pass emissions if 2 codes are deleted one will still pop up when they scan it at the emissions testing. Could you explain how this relocating goes? I don't know a whole lot about the bpv, was on when I had bought the car.

 

relocate is kind of a pita.


get the bpv,
buy and install this.

no more worries and you still get a **** load of noise. I have it on mine.

 

But if you want to relocate the maf you will need a zzp lower charge pipe if you dont have it, the relocate harness like 30 bucks i think, and a block off plate to block the port in the intake ( should come with the charge pipe). If not what northvibe said is correct and im running that same set up with a forge bpv recirculate

 

So with that bpv there should be no codes?

 

That all depends. If the code is unrelated to the unmetered air, then yes that code will still happen.If the code was caused by venting then it would correct that. It vents the extra to the intake pipe as it was already read by the ecu. I don't think you listed your cel in the thread...unless I missed it. But it is common to throw a code venting to atmosphere without the proper setup.

 

I will get a code reader and put the code on here as soon as I get it.

 

usually auto parts stores have them for free to pull in parking lot...but ya post it up!
