nice picture
it is true that you would need a sensor with much greater "range" on a turbo car since it compresses the air and therefore it will reach much higher temperatures, also it would need to be placed in the intake manifold.. after the air has been compressed, and after intercooler, thats why it has the external IAT.
(if you know the flow and the IAT, your ecu can calculate the density of the air entering the engine)
..but the integrated sensor is great for NA cars since u dont have to use another iat sensor in that setup.. id imagine this same sensor could be used in a blow thru maf turbo setup.. if the maf were to be placed after the ic..
