2003-2009 Zt-2 Wideband has a Non Linear Wideband
Output (white wire). See graph below
2006-2009 Zt-2 Wideband has two wideband outputs. The Linear
Wideband Output and the Nonlinear Wideband Output, which follows a natural
output curve of Bosch LSU wideband O2 sensor.
The Zt-2 Linear Wideband Output is shared
with the Narrowband Output (the Zt-2 purple wire). Typically the engine
management systems use only a narrowband or a wideband O2 feedback.
2010 Zt-2 Wideband has one Linear Wideband Output (white wire)
2010 Zt-3 Wideband has one Linear Wideband Output (white wire) which is a
configurable output. The default output matches the Zt-2 2010 output and
the Zeitronix Data Logger software may be used to configure the output AFR
voltages to match 3rd party engine management systems or gauges.
Zt-2 Linear Wideband Output transfer function
is: AFR= 2 * V + 9.6
For Use with 3rd party systems enter values as follows: 0 Volts = 9.6 AFR, 5.0
volts = 19.6 AFR
Dual Wideband AFR is possible using
the linear wideband output. Two Zeitronix wideband units can be
together by connecting the linear wideband output of a second wideband
controller to the "User2" input of a Zt-2. The dual bank air/fuel ratio can be
displayed on an LCD, Gauge or software and logged on a Black Box Data Logger.
channel air/fuel ratio configurations are available.
2006-2009 Zt-2 Wideband
The Zt-2s purchased after September 1 2006
are equipped with the Linear Wideband Output. To set up the Linear Wideband
Output please open the ZDL software V 2.0.8 or later and chose the 0-5V Linear
Wideband Output from the Settings/Narrowband Output Pin menu. The Zt-2 purple
wire becomes the Linear Wideband Output.
2003-2009 Zt-2 Wideband
These Zt-2 Widebands are equipped with the
Nonlinear Wideband Output (the Zt-2 white wire). This output follows a natural
curve of Bosch LSU wideband O2 sensor.
