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, and Air/Fluid temperature 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!

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 Wideband Air Fuel Ratio Meter is a must for a serious tuner!  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 74 samples per seconds per graph. The ZDL software can be utilized as a real time display when using a basic Zt-2 kit without the hardware display.

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.

NEW!!!  Zeitronix Wideband LCD Display Features

- Display LCD top line as:  Lambda and AFR / User2 and AFR / Lambda and U2 (User2).
  (User2 can be setup as:   Oil/Air/Water Temperature, Oil/Fuel Pressure, and Boost!
- Display LCD bottom corner as Boost, Throttle Position, or User1 (0-5 volt sensor).
- Display in imperial or metric units.

LCD Setup Overview
 

Yes, you can be fast without the A-pillar gauges. The LCD display gives you a stealth look and important data in high contrast digital format.  The aluminum enclosure dimensions are 4.7" x 2" x 0.9" , slightly larger than the LCD display itself. The LCD fonts are bright white on a black background. High contrast LCD digits are visible even in a direct sunlight.  A push of a button located on the right side of the LCD shows peak and hold maximum AFR, Lambda, EGT and Boost values.  The LCD display communicates with the Zt-2 digitally through a serial interface. This allows for a clean display installation in the car, since all heavy wire connections are going to the Zt-2. The display serial cable is thin, black and easily blends with the dash.  The new overlay is made from hard coated, scratch resistant material.

We also offer new round gauges, AFR/Lambda ZR-1 and ZR-2 Multi Gauge.
Both gauges "read" the Zt-2 digital serial data stream. For super clean and easy installation, just like our LCD display, the gauges plug and power up directly into the Zt-2 data port. There are no extra wires for power connections!
