Zeitronix ZT-3 Wideband AFR Air Fuel Ratio Meter

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.

The new Zt-3 has the same high quality, high precision air fuel ratio readings as our signature Zt-2 wideband. The Zt-3 supports wideband air fuel ratio and lambda readings, adjustable simulated narrowband output and a new configurable linear wideband output for ease of use with engine management systems and 3rd party gauges.

No matter if you have a stand alone engine management system, a piggy back fuel control or a carbureted engine. The Zt-3 Wideband Air Fuel Ratio Meter is a must for serious tuners!  Finally you can tune for more power, closer to the edge, precisely monitoring Air/Fuel ratio and datalogging up to 9 hours of data with a blazing rate of 65 samples per second per graph. The Zeitronix Data Logger Software can be utilized as a real time display when using a standard Zt-3 kit with or without the ZR-1 or DashDAQ displays.

The new Zt-3's dimensions are only 3 by 2 by 1 inches.  The case includes slots case for easy zip tie mounting in a tucked away location.
