1. Uvod
This manual provides comprehensive instructions for the installation, operation, and maintenance of the Haltech WB1 Single Channel CAN O2 Wideband Controller Kit. The WB1 controller is designed to accurately measure and report exhaust gas oxygen content (Air/Fuel Ratio) to a compatible Engine Control Unit (ECU) or data logger via a CAN (Controller Area Network) interface. This kit includes a Bosch LSU 4.9 sensor, ensuring precise and reliable AFR data for optimal engine tuning and monitoring.

3. Nastavitev in namestitev
3.1. O2 Sensor Installation
- Izbira lokacije: Choose a suitable location in the exhaust system, typically after the turbocharger (if applicable) and before the catalytic converter. The sensor should be positioned at least 18 inches (45 cm) from the exhaust port to avoid excessive heat, which can damage the sensor.
- Bung Welding: Use the provided weld-on bung. Ensure the bung is welded securely to the exhaust pipe, creating a gas-tight seal. The sensor should be installed at an angle (at least 10 degrees from horizontal) to prevent condensation from collecting in the sensor element.
- Namestitev senzorja: Carefully thread the Bosch LSU 4.9 sensor into the welded bung. Tighten it firmly, but do not overtighten.
3.2. Controller Mounting
Mount the Haltech WB1 controller in a secure location away from direct heat, moisture, and excessive vibration. Ensure adequate airflow around the unit for cooling. The controller is not waterproof and should be installed inside the vehicle cabin or a sealed enclosure.
3.3. Povezave ožičenja
- Povezava senzorja: Connect the Bosch LSU 4.9 sensor harness to the designated port on the WB1 controller. Ensure the connection is fully seated and locked.
- Napajanje: Connect the provided power supply cable to the WB1 controller. The red wire should be connected to a switched 12V power source (e.g., ignition switched power), and the black wire to a reliable chassis ground. Ensure proper fusing for the 12V supply.
- Povezava CAN: Connect the CAN cable from the WB1 controller to your Haltech ECU or other compatible CAN device. Refer to your ECU's wiring diagram for specific CAN input connections. Ensure the CAN bus is properly terminated if the WB1 is at an end of the bus.
4. Navodila za uporabo
Once installed and wired correctly, the Haltech WB1 controller will automatically begin to heat the O2 sensor upon receiving power. The controller will then transmit real-time Air/Fuel Ratio (AFR) data via the CAN bus to your connected ECU or data logger. No user configuration is typically required on the WB1 unit itself, as it is pre-calibrated for the Bosch LSU 4.9 sensor.
- Obdobje ogrevanja: Allow a brief warm-up period (typically 30-60 seconds) after power-up for the sensor to reach its operating temperature and provide accurate readings.
- Spremljanje podatkov: Monitor AFR data through your Haltech ECU's software (e.g., ESP software) or your connected data logging device.
- Normalno delovanje: The WB1 continuously measures and outputs AFR. Fluctuations in AFR are normal during engine operation, especially under varying load and throttle conditions.
5. Vzdrževanje
- Življenjska doba senzorja: The Bosch LSU 4.9 O2 sensor is a consumable item. Its lifespan can vary significantly depending on fuel type, engine condition, and operating environment. Typical lifespan ranges from 30,000 to 60,000 miles (50,000 to 100,000 km) for street use, but can be much shorter in high-performance or race applications. Replace the sensor if readings become erratic, slow to respond, or consistently inaccurate.
- Preverjanje povezave: Periodically inspect all wiring connections for corrosion, fraying, or looseness. Ensure the sensor is securely threaded into the bung.
- Controller Inspection: Ensure the WB1 controller remains free from debris, moisture, and excessive heat.
6. Odpravljanje težav
| Simptom | Možen vzrok | rešitev |
|---|---|---|
| No AFR reading / Sensor not heating | No power to WB1 controller; faulty wiring; faulty sensor. | Check power and ground connections. Verify 12V supply. Inspect wiring for damage. Test with a known good sensor if available. |
| Erratic or inconsistent AFR readings | Exhaust leak near sensor; sensor contamination; aging sensor; electrical interference. | Check for exhaust leaks. Inspect sensor tip for deposits. Replace sensor if old. Ensure power/CAN wiring is away from ignition components. |
| Incorrect AFR values (offset) | Incorrect CAN configuration in ECU; sensor calibration issue (rare for LSU 4.9). | Verify CAN settings in your ECU software match Haltech's recommendations for the WB1. |
| Napaka v komunikaciji CAN | Faulty CAN cable; incorrect CAN bus termination; incompatible CAN settings. | Check CAN cable for damage. Ensure CAN bus termination is correct (typically 120 Ohm resistors at each end of the bus). Verify CAN baud rate and ID settings. |
If troubleshooting steps do not resolve the issue, contact Haltech technical support for further assistance.
