is a mass air flow sensor the same as a map sensor
MAP sensor Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion (see stoichiometry) and influence the advance or retard of ignition timing. A fuel-injected engine may alternatively use a mass airflow sensor (MAF sensor) to detect the intake airflow. A typical naturally aspirated engine configuration employs one or the other, whereas forced induction engines typically use both; a MAF sensor on the intake tract pre-turbo and a MAP sensor on the charge pipe leading to the throttle body.
Apple Maps Speculation around Apple creating a mapping service of its own arose in 2009 after computer magazine Computerworld reported that Apple had acquired the company Placebase, an online mapping service, in July of that year.[10] Since then, the CEO of Placebase became a part of Apple's "Geo Team".[11][12] In the following two years, Apple acquired two more mapping related companies who specialized in 3D maps: Poly9 in 2010 and C3 Technologies in 2011.[13][14] C3 Technologies' imagery was later used for the Flyovers feature in Apple Maps.[15] Earlier in 2011, Apple indicated its plan for a mapping service when it stated on its website that it was collecting location data to create "an improved traffic service in the next couple of years" for iPhone users.[16] In September 2012, when Apple Maps was released, a source connected to both Google and Apple Maps claimed to technology website TechCrunch that Apple was recruiting Google employees that worked on Google Maps.[17]
