Description

The Zietronix 5 Bar (75psi) absolute pressure sensors measure both negative pressure (vacuum) and positive pressures.

These Manifold Absolute Pressure (MAP) sensors provide a very useful engine load measurement, these rugged sensors can withstand use monitoring fuel or other automotive fluid pressures.

The sensors can be used with the Zt-2 as a boost sensor or with your own engine management system (EMS) or datalogger.

To make an educated tuning decision you need at least RPM and engine load reference alongside the AFR number.

We offer very accurate and temperature compensated MAP sensors in two flavours, 50 PSI (3.5 BAR) and 75 PSI (5 BAR), those absolute values translate to 35.3 PSI (2.5 BAR) and 60.3 PSI (4 BAR) gauge pressure.

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:

75 PSI Sensor

0 volts

-24.075 psi

5 volts

69.675 psi

Sensor pressure readings can also be expressed as an equation based on voltage:

  • 75 psi sensor: pressure = 18.75 x voltage - 24.075

Installation Tips:

  • These rugged stainless steel MAP and gauge pressure sensors come with a weather sealed connecting harness.

  • A hose 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 on a 1/8 NPT aluminium bung and thread the MAP directly into the intake manifold.
