Zeitronix (MAP) Boost Sensors Zeitronix Gauge Pressure Sensor
These absolute pressure sensors come in 50 PSI (3.5 Bar) and 75 PSI (5 Bar) sensors.  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.  These sensors can be used with the Zt-2 as a boost sensor or with your own engine management system (EMS) or datalogger. Our 150 PSI (10 Bar) gauge pressure sensors measure  positive pressure only and are not for use as boost sensors with the Zt-2.  Instead their ruggedness and range provides a perfect too for monitoring fuel or other automotive fluid pressures.  Connect to the Zt-2 "User Input" and monitor in the Zeitronix datalogger as a  0 to 150 PSI or a 0 to 10 Bar signal, or connect to your own engine management system (EMS) or datalogger.

Zeitronix MAP (Boost) Sensor Installation Tips
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 flavors, 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.

These rugged stainless steel MAP sensors come with weather sealed.  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.  For full race application you can also weld our 1/8 NPT aluminum bung  and  thread the MAP directly into the intake manifold.

Connect three MAP Sensor wires to the Zt-2 as follows:

Zt-2 Wire Color MAP Sensor Wire Color
YELLOW (+5V Supply) RED

ORANGE (Boost Input) GREEN
