Our classic silver aluminum clear anodized LCD enclosure. Includes the Zt-2 Wideband Air/Fuel Ratio Meter, Wideband Oxygen Sensor, Sensor Harness, Signal Harness, PC Serial Cable, Datalogging Software, Installation Instructions, 2 pin EGT connector to retrofit your EGT probe and Zeitronix LCD Display with peak and hold feature. High contrast LCD visible even in a direct sunlight.

Yes, you can be fast without the A-pillar gauges. 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" , 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.

No matter if you have a stand alone engine management system or a piggy back fuel control, 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.

Fully digital, smallest Wideband O2 controller in the world!

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

Datalogging Software
Datalogging Software
The Zt-2 communicates with the PC Laptop via the serial port. The 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.Win92/98/NT/2000/ME/XP 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.
