Installation
Requires Zeitronix Zt-2 for operation. The ZR-2 Multi Gauge works with all versions of the Zeitronix Zt-2 Wideband AFR meter and Datalogging System. The ZR-2 Multi Gauge plugs into the Zt-2 DATA port. Power and serial data is supplied directly through the single connector. No additional +12V or ground  wires required. The ZR-2 Multi Gauge cable length is 5 ft (1.5m).

Made in USA

Fail-Safe Operation
Add robust failsafe gauge 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.

Fail-safe setup

Dual Channel Wideband AFR
Dual channel AFR readings are available with two AFR readings being displayed on one ZR-2 gauge. The outer edge of LEDs supply one AFR reading while the inner digital readout shows the second air/fuel ratio. Multiple display and datalogging options are available running a dual bank setup.

 

Multiple Widebands with Black Box Data Logger and Optional Display

Multiple Gauges Supported
3 Gauges Connected to one Zt-2

A splitter is included with each display allowing up to 3 displays to be linked to single Zt-2. Details.

Mounting
The ZR-2 gauge is only 3/4" (19mm) thick. The back of the gauge is completely flat with cable hidden in a cavity and can be surface mounted almost anywhere inside the car cabin using a piece of Velcro or double sided tape. The ZR-2 base allows the gauge to be mounted in a standard 2 1/16 (52mm) gauge pod. For additional mounting options the package includes 2 set screws and 2 nuts (4-40 screw size).  Check out the gallery for gauge installation pictures.
