PLX Devices offers a complete line of Accurate, Wide band 02 Air/Fuel Ratio devices / gauges.
Wideband 02 Air Fuel
All M-Series Controllers come with two analog outputs, linear wideband and narrowband.
Their linear wideband output gives you the freedom to interface with a number of tuning devices,
piggy back fuel systems and stand alone engine management systems. With the narrowband output you
are able to completely replace your stock narrowband sensor and "feed" our analog signal directly
into your ECU. This eliminates the hassle of welding a second sensor bung on your down pipe.
Your ECU will "think" that your narrowband sensor is still there while you're measuring wideband
information at the same time!
The M-Series Wideband Oxygen Sensor Controllers are extremely simple to use and to setup. Simply,
connect the power wires to a 12V source, snap the sensor wire harness with the oxygen sensor and
you're ready to start measuring your automobile's air/fuel ratio within minutes!
The M-400/M-500 features a built-in 6 input(2 speed, 4 analog) data logger. The 2 speed inputs
can be connected to any signal which gives a pulse (Freq Range: 0Hz-10KHz) and the 4 analog inputs
can be connected to any signal which gives a voltage between 0-5V. Analog voltages between 5V-25V
will be capped at 5V and will not damage the data logger. Here are a few examples of signals that
can be logged by the M-400/M-500.
With PLX Devices you can tap into the signal, and datlog with your own device, such as the GReddy e-manage, Hondata or AEM EMS
Or you can purchase a PLX kit that includes software, to datalog on your laptop
