Zeitronix Wideband Air/Fuel Ratio Meter Systems

Yes, you can be fast without looking like a UFO just landed. The remote 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”, which is just 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.

Pushing the 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.

Fully digital, smallest wideband O2 controller and datalogging system in the world!

Zt-2 controller is about the size of 1" thick business card.
Extremely compact design for installation where space is a premium

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.

Win92/98/NT/2000/ME/XP/Vista 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.
