Zeitronix ZT-4 Dual Wideband AFR Meter | V6/V8/V10/V12 Engines (ZT-4)

ZT-4 Dual Wideband AFR Meter for V6/V8/V10/V12 by Zeitronix

Zeitronix Zt-4 Dual Wideband Air/Fuel ratio meter is a simple to use high quality, stand-alone system for carbureted and electronic fuel injection engines. The new Zt-4 has the same high quality, high precision air fuel ratio readings as our signature Zt-2 wideband. The Zt-4 supports wideband air fuel ratio and lambda readings, adjustable simulated narrowband outputs and configurable linear wideband outputs 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-4 Wideband Air Fuel Ratio Meter is a must for serious tuners! Finally you can tune for more power, closer to the edge, precisely monitoring both banks of V engine Air/Fuel ratio. Optional 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-4 kit with or without the ZR-4 or DashDAQ displays.

The Zt-4 communicates with the PC Laptop via the serial port using optional serial cable. The Zeitronix Data Logger (ZDL) software records up to 9 hours of data per single file. Many different screen display options are available including plots, text and dashboard views and uses a black plot background for easy night tuning. Logging start, stop and pause are accessible from keyboard shortcuts. The ZDL software supports excel CSV and text data export.
