DTN, you don't need the MAP adapter or anything. LOL
just boost your MAF sensor. it is proven and tested!!!
i'm pushing 9psi with boosted MAF + venting to atmosphere!
Not a single problem at all! laugh.gif

^^ I've heard that was too hard on the MAF. Guess not.
Shim: Guess MAF relocation to after your BOV is in order. That is an easier soloution then a MAP sensor. But your problem is still that your MAF is reading alot more air then what's going into your engine. You're running rich.

Edit: Is it ok to put the maf after the turbo and iat?
Well I'm not sure to be honest with you. I'll have to look it up. Would you by chance know if the smt6 has that?
If nate's idea doesnt work out, I'll give this a shot!
Thanks for the input man.
What do you mean by "boost your maf sensor?"

Does your fuel computer or management device have anti stall function when you vent your BOV to atmosphere?
If you don't, it is the cause of all that stall problem.

You need to recirculate your air before your MAF. If the computer thinks you're getting 50 Gallons of air/minute, because that's the ammount passing your MAF, it will add that much fuel. The BOV should be recirculated in a manner so that the air that passes the turbo gets re-routed back into the input of the turbo so that new air is not passing the MAF to compensate for the blow off.
The computer is saying "we might be at closed throttle, but we're still getting 30 GPM, so we need a bunch more fuel". So the computer adds too much fuel until your turbo spins down to a level that dosn't activate the BOV.
The soloution to the problem is to get a MAP adapter for your MAF sensor. My buddy has an eclipse we're turboing and is currently looking at that soloution to get the cool "sssshhhHHHHH-T-hhhhhhhh" sound.

Yes, you can run the ACTUAL sensor, but it's difficult to run the housing with the sensor. If your boosting over 10-12psi it will continuously pop off...
Contact Denis, his shop makes MAF housings esp for turbo set ups. I've made a couple as well at my machine shop, but I won't sell them online because Denis has that side covered.

^^^ I'm currently only running 8psi, so I'll try it out first but if it pops off i'll talk to Denis.
Thanks alot guys! I'll try moving it on sunday when I don't have classes/work.
Oh, one last thing. Will I have to move the iat sensor to after the turbo and maf as well, or should it be alrite before the turbo still?

YES, DTN.
our car can have a non recirculated BOV easily.
Boosted MAF means that MAF sensor is located approximately 12 inches from TB.
Also, I am using SMT6, but you don't need any anti stall function (I don't think SMT6 even has that function) for my setup.
Also, my A/F ratio is at around between 14.5 and 15.0 when I am off boost which means I am not running rich due to the boosted MAF.

Nissan guys with upgraded Turbos got stalling problems after giving their cars a bootful due to air pressure waves caused by the turbo induction fooling the MAF into thinking strange things. It was easily fixed by placing the MAF in the charge piping.

You can get the full story on my topic, but yea, my problem is related to the MAF as well... essentially when I pull the clip for it and run without a MAF I'm better than with it on.
So yea, moving yours would fix yours, doubt it would mine but I might end up trying it eventually.
