Chapter 2 – LCU-ONE and Lambda probe mounting
LCU-ONE controller should be installed in a flat location and far from heat sources; it
should be mounted steady using the suited bracket.
The wiring has to be arranged so to avoid it passing near to heat sources.
LCU-ONE is to be powered by the engine master switch.
BOSCH LSU 4.9 Lambda probe should be installed on the vehicle exhaust pipe using a
specific adaptor that comes with the kit and should be welded on the same pipe. The
probe should be sufficiently near to the engine.
Probe working temperature should not exceed 900°C (1652°F) and it should not be
exposed to the free flame coming from the exhaust system.
Probe installation angle should be of at least 10° to avoid liquid condensation stuff to
come in contact with the probe, polluting it.
Once the probe is installed, pay attention not to let the cable pass near to excessive
heat sources (the exhaust pipe for example).
Bosch LSU 4.9 probe auto-calibrates: no calibration is then required by the user.
Solvents or additives should not be used to clean the probe connector. To protect
the probe we would suggest to remove it from the vehicle when cleaning the
vehicle to avoid polluting the probe with detergents.
It is reminded to never switch the vehicle on with Lambda probe installed and not
connected to a correctly working LCU-ONE controller: a probe not heated and exposed
to exhaust gas would be irremediably damaged.
N.B. BOSCH LSU 4.9 Lambda probe has been designed to be used with unleaded
or diesel engine: it can be used with other kind of engines too but its duration
needs to be tested by the user.
