Includes the Zt-2 Wideband Air/Fuel Ratio Meter, Wideband Oxygen Sensor, Sensor Harness, Signal Harness, PC Serial Cable, Datalogging Software, Installation Instructions and 2-Pin EGT Connector to retrofit your EGT probe. Data splitter included for simultaneous display and datalogging use. Made in the USA.

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. The Zeitronix system provides the accuracy of a Dyno Air/Fuel reading right in your vehicle as well as multiple engine parameters. 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!

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. IMPORTANT: Warranty does not cover oxygen sensor, as these are wear items.  Each oxygen sensor is tested to be fully functional by Zeitronix before shipping.
