I have never personally tried it, but I am under the impression that the loss of resolution at lower airflow can make it difficult to tune low-load areas of the map. Where that comes into play, I am...

Well the VPC just replaced the MAF all-together and didnt offer that option. Someone would have to design and build an all new electronic tuning product for that. At least, I have never heard of...

This is basically what the oldschool HKS VPC did. MAP piggyback that outputs a simulated MAF signal to emulate the original sensor.

This will not work on the 370z. Unless you locked the VVEL...

Same part number as what? As the Z? if so, that would be no good

But they are using them pull-through, right? If they are using them pull-through and getting HP that would be high for a 370z, then they might work out really well for us in a blow-through...

Ah ya youre right, "brain-fart", changing the temperature of the air after the MAF doesnt change its volume it just changes its density.

I am very aware of the air temp sensor in the MAF! You are correct, it is required for the MAF to properly function.

What I am talking about is how the MAF sensor in a pull-through configuration...

Exactly. Tuning with a blow-through MAF configuration is sort of a middle-ground between MAP tuning and MAF tuning. With a pull-through MAF configuration, we would get the results we want to expect...

The discrepancy I believe you are missing is that a MAF sensor is not "boost-smart". Once you are using the MAF sensor in a blow-through application, while you will maintain repeat-ability in the...

Airflow and pressure are not directly relative anywhere you take reading or measure. Different turbo systems on the same engine will achieve different airflow mass at the same pressures. Which is why...

For reference, with my Greddy kit that uses 2.75" MAF tubes, my MAF voltages are ALMOST maxed out in the 9psi area. I hit 4.9's in voltage. But boost pressure is not exactly an indication of airflow.
