WB MOUNTING

Mounting

The Haltech Wideband Controller can be mounted to a flat surface in the engine bay using the two mounting holes provided in the enclosure.

The controller should be located as far as possible from any extreme sources of heat (exhaust, turbocharger, etc.)

Although the Haltech WB1 / WB2 Controllers are sealed units, it is good practice to mount them in an orientation that prevents water from collecting on the connector(s).

WB MOUNTING WB WIRING / DAISY CHAIN SETUP

Wiring

Connect the controller to the Haltech CAN Bus on your ECU by the integrated DTM-4 connector on your device.

Connect the NTK or Bosch LSU 4.9 Sensor(s) via the available pre-terminated cables from the controller.

Note: Haltech Wideband Controllers draw up to 4A per sensor during cold startup.

When running multiple controllers in a “daisy chain”, they can require more power than the CAN Bus circuit delivers.

It is required to run a fused and switched 12V source (supplied by a relay) to power these controllers at Key On and Key Start positions.

NEXUS R5 WIRING

Wiring for NEXUS R5 ECU

The NEXUS R5 has two on-board wideband controllers already, but we give you the option to add additional sensors. In order to use this feature, users will have to purchase single or dual WB controllers and wire them into the Haltech CAN BUS that the user has selected (CAN 1, 2 or 3).

Users will have to configure which WB controller they are using in the NSP software, including determining which CAN BUS they are using to transfer information to the VCU.

Basic harnesses can supply up to 8A of power draw for the CAN BUS wiring. It is recommended to use power harness, HT-130043 when connecting multiple devices where peak draw exceeds output of standard HCO.

The NEXUS R5 includes three separate CAN buses, users must select ONE HALTECH CAN network for unit to work correctly. Follow the chart below to identify which CAN networks are available for use.

Connector A:
Port 1 – CAN H (A23 White)
CAN L (A24 Blue)

Connector B:
Port 3 – CAN H (B13 White)
CAN L (B19 Blue)

Connector C:
Port 2 – CAN H (C21 White)
CAN L (C22 Blue)

Nexus R5 Wiring

SENSOR INSTALLATION

Placement

The best location for the sensor is approximately 1 metre (3’) from the closest exhaust valve (measured along the central axis of the exhaust pipe) or 1 metre (3’) from the turbo outlet (for turbo charged vehicles).

Mounting

The sensor requires the included 303SS bung to be welded into the vehicles exhaust system. Weld the bung into the chosen position and install the sensor.
It is recommended that the sensor be orientated in such a way that minimizes any condensation entering the sensor during warm up and operation.

Wiring

Connect the wideband sensor to the pre-terminated 6 position connector on the Wideband Controller. Ensure all wiring is away from extreme heat sources and secured in place.

Enabling Multiple Wideband

If two or more Haltech WB devices are connected to an ECU, each device must be allocated a unique device ID to function correctly. Haltech CAN wideband controllers are shipped from factory as device ID “A”.

Up to 4 individual Haltech WB2 devices may be supported, depending our your ECU. Elite ECU’s can update the device ID’s through the Devices tab in ESP.

• Connect the Wideband to be updated and enable the device as previously noted.
• Select the “Options” tab and a menu will appear.
• Select “Change device ID to B”.
• Connect the next device and repeat the process until each device is allocated a unique ID.

Once each device has a unique ID, the ECU must be reset. The sensors may now be enabled and allocated aswideband O2 sensor 1, 2, 3, 4 etc in the Functions tab.

NOTE: Devices which share the same ID will show an error if both devices are connected at the same time. One of the devices in error will need to be disconnected from the ECU before re-programming.

SOFTWARE SETUP

ESP Software Setup

With the Haltech CAN Wideband Controller installed, it is now time to set it up in the software. When powered up and connected to ESP, your Haltech ECU will automatically recognize the new device which will be shown in the Devices tab.

To enable the device, click on the “Options” tab and select “Enable Device”. Alternatively, the device may be enabled by accessing the “Devices” page within the Main Setup menu.

The ECU must now be reset. Once the ECU is reset, the device tab should change from “Device Found” to “Online”. Once the device is online, the sensors may be enabled and allocated as Wideband O2 Sensor 1 or 2 in the Functions tab.

NSP Software Setup

Now that your Haltech CAN Wideband Controller is installed, let’s set it up in NSP software. With it powered and connected, your NEXUS will automatically recognize the new device.

To enable it, click on “Connections”, select the drop down “CAN” and choose the “Haltech CAN System” prompt. Here we can enable our various CAN based devices.

Once completed, reboot your NEXUS and select the new device menu item. Finish the setup by enabling your controller.

NOTE: To connect multiple WB2 devices, users will need to purchase pre- programmed units (Box B, C, & D) or speak with their dealer about reprogramming existing devices.
