subaru map sensor

[emlclcy]

on my Subaru engine there is a DENSO 22627AA170 MAP sensor.
Does M/S need to know how this sensor is calibrated or is a relative thing and is calibrated as part of the tuning?
cheers

MS2 could probably be calibrated with a custom calibration curve, but you will need to know what kPa the sensor is reading at 0 and 5 volts.

ran into a brick wall on this one, can't track down a datasheet.
short of taking it of and measuring it under vacuum/pressure!
