Zeitronix Zt-3 Wideband Kits

The Zt-3 reads AFR and Lambda.

The Zeitronix Wideband Air/Fuel ratio meter and datalogging system is a high quality, stand-alone system for use with carbureted and electronic fuel injection engines.

The new Zt-3 has the same high quality, high precision air fuel ratio readings as our signature Zt-2 wideband. The Zt-3 supports wideband air fuel ratio and lambda readings, adjustable simulated narrowband output and a new configurable linear wideband output for ease of use with engine management systems and 3rd party gauges.

The new Zt-3's dimensions are only 3 by 2 by 1 inches. The case includes slots case for easy zip tie mounting in a tucked away location.

Installation Instructions
Zeitronix Data Logger Software
Configurable Simulated Narrowband Output
Replace the signal from your stock narrowband oxygen sensor for increased fuel savings or smoothed idle RPM.

Configurable Wideband Output
Match the Zt-3 Wideband output to your engine management system, data logger or a third party gauge.

Zt-3 System
No matter if you have a stand alone engine management system, a piggy back fuel control or a carbureted engine. The Zt-3 Wideband Air Fuel Ratio Meter is a must for serious tuners! Finally you can tune for more power, closer to the edge, precisely monitoring Air/Fuel ratio and datalogging up to 9 hours of data with a blazing rate of 70 samples per seconds per graph. The ZDL software can be utilized as a real time display when using a standard Zt-3 kit without the ZR-1 or DashDAQ displays.

Installation
Very simple installation - connect two wires to +12V and ground and place the O2 sensor in the exhaust stream and you are ready to read AFR! A simple LED indicator displays off, warm-up and running modes.

ZDL Datalogging Software
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.
You do not need P4, P3 or even P2 laptop. We understand that you want to leave your new laptop at home and dedicate the old one to car tuning. We give you well optimized software. If your laptop is capable of running Win95 and up it is good enough for the Zeitronix logging software.

The digital gauge screen option could be used when purchasing the Zt-3 without a display.
