Now we know on the 5th gen on the supercharger kits the MAF sits on the intake piping NOT the charged/pressure pipe like it does on the 4th gens.

Now my question is with all the issues on 5th gens with the Blowoff valves. Since the MAF reads the air coming in and then the BOV dumps it, this is what is causing the stalling.

Would it be wrong if I put the MAF on the charged pipe right before the throttle body like in the 4th gens? Seems like the best spot, but dont want to run into MAF issues cause dont know if it is not designed for charged pipe application.

I dont see how it could hurt anything.

 

Thanks Matt. I will put it on the charged pipe to avoid BOV stalling issues.

Car is under the knife as we speak.

Is this a case where you would route the BOV back into the intake to prevent stalling? I'm not sure if this is only for applications that have a chip re-burn though. Boosting through your MAF will max out the signal and your A/F will be way off.

 

then that would make the 4th gen AF ratio off as well same concept not unless stillen knows something we dont know.

 

i think maxi-overdose has that setup (i think y2kevse installed it). The BOV is right before the TB on the charged pipe.

hope you don't mind maxi...

 

Yea all 5th gens put the BOV on the charged pipe since there is no MAF on the charged pipe. That was the point I was trying to make that If you put the MAF sensor between the BOV and Throttle Body, that would automatically elimate the stalling issues since the BOV can release all the air it wants, the MAF doesnt read that air.

The issue without doing that setup is that with the MAF on the intake side, it reads the air, assumes it went into the engine, and then the BOV releases it, that means the ECU puts extra fuel where the air never got there. This is what causes the stalling. Putting it after the BOV and before the Throttle Body solves that because MAF would register that air.
