MAP sensor = manifold absolute pressure sensor. As the name implies, it measures absolute pressure in the intake manifold (or where ever you have the sensor located). What that does for me............it allows me to wire the sensor into DSMLink with a 0-5v analog signal in order to log this variable and to double check the "calculated" numbers I'm seeing inside a log with "real" numbers for a more precise tune.

I don't know the application that HAHN is using it for, so I can't say.
