Relocating MAF
Does anyone have any experience with relocating the stock MAF? When I bought the car I didn't know anything about turbo cars, but I saw the CBV was broken, so I bought a turboxs. It doesn't recirculate, and I don't have the money right now to change to the GM MAF. Is it worth a try to relocate , or should I just live with it until I can change it?

Re: Relocating MAF
If by relocate you mean put after the turbo, its not possible on the stock MAS. One reason people go to the GM MAF, which is a different type altogether, is to do this.

Yes, I meant after the turbo. Not possible why? Won't hold boost? It was just an idea, and I couldn't find any info about it so I thought I'd ask.

OR, are you saying that they are two completely different sensors. Is that why it won't work? I am confused now, because I thought they worked the same.

Re: Relocating MAF
Yeah, there is very little info, since it just cant be done. Our MASs are of the Karmen Vortex type. You can plug that into google and find some animations and info on what a karmen vortex is though. Basically the MAF flows air over a strategically placed obstruction, that creates turbulence in a repeatable pattern. By counting these patterns, the MAS gets velocity. Combined with a know metering area to MAS area ratio it can determine volume flow. It sends that signal along with baro pressure and air temp so the ECU can calculate mass flow.
Under pressure, air wont react the same way inside the MAS, and it cant properly read airflow. The MAFt setup uses a GM "hotwire" MAF. A heated wire is suspended across the sensor. As moving air strikes it, heat is carried away by the air molecules. The sensor monitors the voltage/current required to maintain the temp of that wire. The more power needed to keep it heated, the more air is crossing it. Pressure and temp are accounted for, since its the number of molecules striking the wire that cools it down. Hence the reason they can be used in blow through mode, and dont have baro and temp sensors of their own. The MAF translator takes the signal from that hotwire MAF and "translates" it into something the ECU can understand and use. Hopefully that helps.
