I’ve been wondering about the location of the MAF sensor in or GN’s, I have the cold air kit that puts the filter under the driverside bumper. The MAF sensor is located in the tubing BEFORE the turbo. I think this is a stock location. So I am thinking that, due to boost, the air coming into the filter is very different than the air going into the intake. So why isn’t the MAF sensor located just outside the intake (maybe before the alcohol spray?) I had always thought that the MAP info went to the ecm which somehow adjusted for boost but I recently found out that the original MAP sensor just fed the dashboard gauge. Maybe somehow all the ecm needs to know is the volume and temp of air entering the system? Is it that even though compressed, the VOLUME of oxygen is unchanged? But after compression and then intercooling the temperature of the incoming air must be very different too? How does this work?
