The Zeitronix Wideband Air/Fuel ratio meter and data logging system is a high quality, stand-alone wideband lambda sensor system. Similar to the Innovate Motorsports MTX-L, the ZT-3 offers a serial data output which can be read directly by Adaptronic Select ECUs, as well as programmable analogue outputs.
The Zt-3 can also log lambda directly to the Zeitronix Black Box Logger, or by connecting the Adaptronic Select ECU using a daisy chain system, the Black Box Logger can log wideband lambda from the ZT-3 and engine parameters such as MAP, RPM, TPS and so on from the ECU.
The Zt-3 comes with an armored sensor cable to protect it from the harsh environment of the engine bay.

How to Install:
Installing Zt-3 is very simple. Just connect two wires to +12V and ground and place the O2 (oxygen) sensor in the exhaust stream and you are ready to read AFR.

Data Logging System:
The Zt-3 communicates with the PC Laptop via the serial port. The ZDL logging software records up to 9 hours of data per single file. Different screen options are available. It has a black background for easy night tuning. The logging start, stop and pause accessible from keyboard shortcuts. Excel and text data export. Win98/NT/2000/ME/XP/Vista/Windows 7 compatible.
The digital gage screen option could be used when purchasing the Zt-3 without a display.
