These rugged stainless steel MAP and gauge
pressure sensors come with a weather sealed connecting harness.
barb connects the MAP to a vacuum line and the connecting harness links to the
Zt-2, EMS or datalogging system. The MAP sensor samples the pressure
reading at the same source point as a boost gauge. Typically it's a vacuum
line connected to the intake manifold.
Both MAP and gauge pressure sensors are suitable for use with as oil or fuel
pressure sensors. For full race application you can also weld our 1/8 NPT aluminum
bung and thread the MAP
directly into the intake manifold.
Setup for 3rd Party Systems|
Third party engine management systems may require pressure sensor values specified for 0 volts and 5 volts levels. Although the sensors read from 0.5 volt to 4.5 volts, values can still be specified to create correct pressure readings on a 3rd party system.
Please see the following table for 0 and 5 volt pressure reading values for the various sensor types:
Sensor pressure readings can also be expressed as an equation based on voltage:
sensor: pressure = 12.5 * voltage - 20.95
