FAQs

What is the primary function of this kit?

The kit provides accurate wideband air-fuel ratio (AFR) readings for engine tuning and monitoring.

Can I connect multiple O2 sensors with this single controller?

This is a single-channel controller. To monitor multiple O2 sensors, you would need additional single-channel controllers, which can be daisy-chained using the DTM-4 connectors.

What is the length of the included sensor cable?

The kit includes a 1200mm (approximately 47 inches) long pre-terminated sensor cable.

Do I need special software to use this controller?

You need the Haltech ESP software to program the controller designation if you plan to use multiple controllers or require specific identification on your CAN network.

Is the O2 sensor included?

Yes, the kit includes a Bosch LSU 4.9 wideband oxygen sensor.

Where is the best place to mount the controller?

Due to its waterproof and compact design, it is ideal for mounting directly in the engine bay, close to the O2 sensor bung.

What is the warranty period for this product?

Please refer to the official Haltech warranty documentation for specific details on the warranty period, as it may vary by region and retailer.

Troubleshooting

Unit not powering on

Verify the 12V power supply connection is secure and the power source is functioning. Check the power supply cable for damage.

No AFR readings or erratic readings

Ensure the Bosch LSU 4.9 sensor is correctly installed and tightened. Check the sensor cable connection for both the sensor and the controller. Verify the controller designation is correctly set in ESP software if applicable. Ensure the sensor is properly heated by the ECU.

CAN communication errors

Confirm the CAN wiring is correct and terminated properly if required by your system. Check for short circuits or open circuits in the CAN bus wiring. Ensure the controller designation is unique on the CAN network.

  3. Connect the 1200mm pre-terminated sensor cable to the sensor and one of the DTM-4 connectors on the controller.
  4. Connect the 150mm power supply cable to the other DTM-4 connector on the controller and to a suitable 12V power source.
  5. If using multiple controllers, connect them in a daisy-chain fashion using the DTM-4 connectors.
  6. Connect the controller to your engine management system or data logger via CAN.
  7. Use the Haltech ESP software to program the controller designation if needed.
