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.
