Ecoboost MAF or No MAF?

I know boost pressure is read right in front the throttle body and manifold contains the working Map. So UR Mod isn't 4/doesn't work so well with a 11 configuration ? Do U change it on the 11 to mod its turbo set up or just program/tune for the O2 frequency ?

The MAF/IAT are most often in an integrated module, both are ALWAYS included in modern day electronics engine controls. Oxygen sensor(s) to control the idle/cruise mode, 14.7 mixture ratio, and MAF/IAT otherwise.

In my mind I agree 100%. I think of a MAF and I think "Screen type" like what Mitsubishi uses. I haven't looked at the sensor itself in the intake, but I would assume it is just a IAT more than anything. That is why on the AFE Stage 2 intake they can split the intake tracks without causing a lean issue.
These days the IAT is simply a diode, and the MAF thermistor is enclosed in a glass bead much the same size/look as the IAT diode, an amplifier within the same module to boost the signal levels.

Thin been all thru this, Ford got the Patent for the part in 2012 to late for the 11. Question is about the 11. Does software/tune simply address the O2 frequency for fuel loop then or is a different maf/iat sensor necessary with the turbo/CAC/exhaust mods on the 11.

Patents can be used PRIOR to the granting of same but if used prior to patent application can be voided.

The patent thing isn't what I'm asking about.
