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 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, Air/Fluid temperature sensors and Oil/Fuel pressure 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! A simple LED indicator displays off, warm-up and running modes. Side LED Image

The Best Wideband for your Tuning Setup
 No matter if you have a stand alone engine management system, a piggy back fuel control or a carbureted engine, the ZT-2 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 Boost, EGT, RPM, throttle position and more. The Zeitronix Data Logger (ZDL) software can be utilized as a real-time display alongside the LCD Display, ZR-2 Multi-Gauge or the DashDAQ display with datalogging for up to 9 hours at a blazing rate of 65 samples per second per input.

On Board Diagnostics (OBDII) is not required but may be monitored through use of the DashDAQ II XL display which reads and clears engine error codes, logs Zt-2 Wideband data and OBDII data and has many additional performance features.

Multiple Widebands with Black Box Data Logger and Optional Display
Dual channel AFR readings are available with multiple display and datalogging options supporting the ZR-2 Multi Gauge, LCD display, Black Box Data Logger and more.

Fail-Safe Operation
Add robust failsafe features using the ZAVT-1 Warning/Trigger Box and optional relay. The Zt-2 Wideband controller will monitor user set levels triggering the ZAVT-1 Warning/Trigger box and optional relay if one or a combination of values exceeds limits. Trigger a failsafe condition on any Zt-2 input including AFR, Boost, RPM, TPS, EGT, Oil/Fuel Pressure, Air/Water temperatures and more. Create a failsafe gauge with the Zt-2 controller watching both displayed values and any other connected sensors or inputs. This simple failsafe safeguard is a great way to protect your engine, hardware and time investment.

ZDL Datalogging Software
The Zt-2 communicates with a PC Laptop via the serial port (USB to Serial adapters may be used). The ZDL logging software records up to 9 hours of data per log file. May screen layout options are available including Dashboard, overlapped or non-overlapping plots with markers and text. The Zeitronix Data Logger software uses a black background for low profile easy to read night tuning. Logging start, stop and pause are accessible from easy keyboard shortcuts. Excel and text file data export available.

Win98/NT/2000/ME/XP/Vista/Windows 7 compatible.
You do not need P4, P3 or even P2 laptop. Leave your new laptop at home and dedicate the old one to car tuning. We give you well optimized software that will run quickly on any hardware capable of running Win95 and up. Download

Multiple ZR-2 Gauge Setup
Up to 3 ZR-2 Multi Gauge Displays Supported!

Exhaust Gas Temperature (EGT) Sensor
Zt-2 reads exhaust gas temperature through a standard K thermocouple, the same as used by most aftermarket EGT gauges. You can retrofit your EGT probe with supplied Zt-2 style 2-pin connector or purchase a new probe from us. Moreover, we offer 8' chromel-alumel extension wire with the Zt-2 style connector in case you need to extend your EGT probe.

Why do I need an Exhaust Temperature Sensor?
Leaner mixture burns hotter giving you more power. Too much heat and things begin to melt. This is when your car is the fastest!. The Zt-2 is equipped with the EGT probe input. The LCD and logging software display the EGT information so take an advantage of it. We offer very economic, high quality, low mass, fast responsive EGT probe which plugs right into the Zt-2. This is a must if you are tuning the car for maximum power. You will be surprised how close to the edge you are running
You will need to tap the headers with 1/8 NPT tap.

Boost MAP Sensor
Absolute pressure MAP sensors read from full vacuum so a 50 PSI range MAP sensor will read from -14.7 PSI to 35.3 PSI gauge pressure at sea level (a 50 PSI pressure range). Vacuum is displayed using the units inHg or mmHg.

The Zt-2's high resolution boost input in conjunction with a Zeitronix Boost Sensor is more accurate than most boost gauges.
3.5 Bar (50 PSI) MAP, 5.0 Bar (75 PSI) MAP, and 10 Bar (150 PSI) gauge pressure sensors are all supported on the Zt-2 Wideband boost input. See our web page for Zeitronix pressure sensors for additional sensor details.

NOTES:
The LCD Display, ZR-2 Multi Gauge and various other displays are option and not required for Zt-2 operation. Additional sensors such as the EGT probe, Boost/Vacuum (MAP) sensor, Oil/Fuel pressure, and Air/Fluid temperature sensors are optional and are also not required for Zt-2 operation. A minimal Zt-2 setup may be used with only an oxygen sensor connected for AFR/Lambda output, for instance to 3rd party engine management systems. For such application consider using the Zt-3 Wideband, which supports only AFR/Lambda sensor readings.
