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.  Zt-2 Wideband Kits provide the best bang for your buck delivering unmatched quality, features and capabilities for very reasonable prices.  Our system provides the accuracy of a Dyno Air/Fuel reading right in your vehicle as well as multiple engine parameters.  Our base system is very easy to install and retails at $279 USD which includes the wideband oxygen sensor, controller, wiring hardware, and the software required to start datalogging and tuning immediately.

Supports Air/Fuel ratio as AFR/Lambda, plus RPM, Vacuum, Boost, Exhaust Gas Temperature, Throttle Position, 0-5 volt sensors, Air/Fluid temperature sensors and Oil/Fuel pressure sensors.  Tune fuel injected and carbureted engines.

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.

Cut your tuning time in half!

No matter if you have a stand alone engine management system, a piggy back fuel control or a carbureted engine. The ZT-2 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 Boost, EGT, RPM and throttle position datalogging up to 9 hours of data with a blazing rate of 65 samples per second per input. The ZDL software can be utilized as a real time display when using the standard Zt-2 kit with or without an LCD, ZR-2 Multi-Gauge or DashDAQ display.

On Board Diagnostics (OBDII) is not required but may be monitored through use of the DashDAQ II XL display which reads and clears engine error codes, log Zt-2 Wideband System and OBDII data and has many additional performance features.

Fully digital, smallest wideband O2 controller and datalogging system in the world!
Zt-2 is about the size of 1" thick business card.  Extremely compact design for installation where space is a premium.

PURCHASE

ZDL Datalogging Software
The Zt-2 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-2 without the LCD display.

Zeitronix Displays

Zeitronix offers both LCD and gauge style displays such as the ZR-1 AFR/Lambda Gauge and ZR-2 Multi Gauge, a Hacker/Tweaker AFR display and the DashDAQ touch screen display.

All displays offer clean and easy installation with power and data through a single wire connecting directly from the Zt-2 data port. No extra wires for power connections!
All displays allow for simultaneous data logging.

        
Multiple displays supported!

Exhaust Gas Temperature (EGT) Sensor
Zt-2 reads exhaust gas temperature through a standard K thermocouple, the same as used by most aftermarket EGT gauges. You can retrofit your EGT probe with supplied Zt-2 style 2-pin connector or purchase a new probe from us. Moreover, we offer 8' chromel-alumel extension wire with the Zt-2 style connector in case you need to extend your EGT probe.

NOTES:
The LCD, ZR-2 and various other displays are option and not needed to read the wideband air fuel ratio from the Zt-2. Additional sensors such as the EGT, Boost/Vacuum MAP, Oil/Fuel pressure, and Air/Fluid temperature sensors are optional and also not required for reading AFR/Lambda.
