The NEW Zt-3 wideband AFR controller from Zeitronix is now in stock!

The Zeitronix Zt-3 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-3 has the same high quality, high precision air fuel ratio readings as our award winning signature Zt-2 wideband controller but without the additional inputs supported by the Zt-2.

The Zt-3 is the perfect choice if you require an accurate, low budget and reliable air:fuel ratio gauge, now using the new and improved version of the Bosch LSU 4.9 sensor.

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.

The 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. Installation is very simple – connect two wires to +12V and ground and place the O2 sensor in the exhaust stream (typically downpipe) and you are ready to read AFR!

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 70 samples per seconds per graph. The ZDL software can be utilized as a real time display when using a standard Zt-3 kit without the ZR-1 or DashDAQ displays.
