Description
The Link Wideband O2 Sensor (LSU4.9) is designed to accurately measure exhaust oxygen content across a wide air-fuel ratio range. When used with a compatible Link ECU or external wideband controller, it provides fast and accurate lambda feedback for precise fuel tuning, closed loop fuel control and engine protection.
Models Supported |
Link ECUs with onboard wideband lambda control. Link CAN Lambda module (PN 125-1000). Other aftermarket ECUs and lambda controllers supporting Bosch LSU 4.9 sensors. |
Warnings |
This sensor is sold solely for aftermarket use. As Bosch's warranty excludes aftermarket applications, no warranty is provided on the LSU 4.9 Sensor. LinkECU have prepared some information about how to increase sensor lifespan below. Install where the sensor is exposed to a representative exhaust gas sample. Install as close to vertical as practical with the wiring facing upwards. Do not install near the end of the exhaust where fresh air may affect readings. Protect the sensor from condensation and excessive exhaust temperatures. |
