Hey I need my car running by tomorrow night since I'm leaving for school so all help would be great. I put my hardpipes on today that has the TB-IC (the longer pipe). I have a vacuum hose that is running from where it goes to the wastegate and I'm using what used to lead to the BPV which is now going to my BOV. No matter what the setting I try I still stall like crazy and it was a b**** getting my car home cause I couldn't drive well in anything but third gear at 3000rpm. Oh, I'm running an injen intake that has the valve that used to have the bpv hooked to it blocked and I also tried without it blocked. Whats going on? Do i need to run the dual setup or am I doing something wrong? I can post pics tomorrow morning if you think that would help.
Urgent Help Please...Hardpipes/BOV

run a seperate vacuum line for the Greddy, then adjust it until the stalling ends.
its a balance between sending enough air through the BPV (which the ECU looks for) and blowing enough air out the BOV to get rid of the turkey and improve performance.
test test test (but first get seperate vacuum lines)
do a search in this forum for BOV + BPV set ups.

this is probably a dumb question but what do you mean by seperate vacuum line. Should I 'T' off of a different line or not. I'd also prefer not having to run a dual setup so I don't have the have a flange welded on for the BPV again since right now I just have the BOV with no BPV
What type of hardpipes do you have? Run the dual setup. It is not necessary to run your BOV off a separate vacuum line than the wastegate, just better. You are stalling because you are blowing off air that the computer expects to be recirculated. You would almost have to have the BOV completely tight (very little sound) to get it not to stall and then you would have mad turkey. People have run without the dual setup, but it sounds like you can't so just try the dual.

pull the battery terminal off and reset the computer leave it off for about 3 - 5 min and then put it back on start the car and rev it till it starts to stall.. if it stalls try it again.. when you reset your computer the car has to learn everything again such as idling this should fix your issue..

let me know if this fixes it.. it should ..CChris704 said:
Our ECU is a "learning" ECU, so this may help. You have to remember that out car has an MAF, and the ECU will never "learn" to ignore the amount of air the MAF reads. The fact that the air is recirculated (uses a BPV) is programmed into the ECU. So, this will help but may not correct the problem. I hope it does though. It is a smart thing to do any time you make a major modification on your car.MazdaSpeedTurbo said:

not true i ran a non recirculating bov for 6 months and never stalled once.. so recirculating is not always the answer. taught my computer how to idle with it non-recirculting..1FASTMSP said:
saw i recirculate the bov...i got the recirc kit just no hose to go from the bov to the intake...but yeah definatley tried reseting the ecu tonight....disconnected the grounding wire and alarm went off when i put it back on....neighborhood probably isn't happy to say the least

Has to do with the amount of fuel dumped. If the MAF reads more air then is going to the TB, then it will obviously dump more fuel thus causing the stall. Our cars have been shown to run different A/F ratios from car to car so if he has one that runs leaner than others maybe that's why he doesn't stall. Who knows? I have to run the dual setup with mine.

Before you look at the pic...yes it is kinda a ghetto setup cause it was supposed to get me to streetstyle and back efficiently but not look pretty. this is the only picture i could take cause my camera died right after the pic and i don't feel like AAA battery searching and yes I do clean my engine bay but we were stalling on main roads trying to adjust the BOV while it was raining.... a VERY long story...
haha and yes the tape on the intake is very cheap but it seemed to stay on there enough to hold on tomorrow...lol
