The Bosch LSM-11 sensor is no longer manufactured. Please see SNSR-01111 for a device capable of emulating the LSM-11 sensor output when paired with a Bosch LSU4.9.
Bosch LSM-11 four wire Wideband O2 Sensor ( UEGO ) for legacy and furnace systems.
About this sensor: This sensor is an older design that is actually a highly tolerant narrow band sensor. In the late 1990's, this was the sensor of choice for aftermarket tuning because no true wideband uego nernst type pump cell sensors were readily available at a reasonable cost.
For some applications this is an ideal sensor because it simply generates a voltage (as narrow-band sensors do) and does not require the advanced electronics of the Wideband O2 systems using more modern sensors. As such, this sensor is ideal for older or legacy applications where the tuner does not wish to use or cannot use a more modern wideband system as is the case for many ECUs made in the late 1990s and earlier. The LSM11 sensor is the wideband sensor used in most older Motec systems, many other ECUs, some boiler, gas, and oil furnace systems.
