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 be far from heat sources.
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), neither 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.
When the probe has been installed, do not let the cable pass close to heat sources (the
exhaust pipe for example).
BOSCH LSU 4.9 probe auto-calibrates: no calibration is then required.
Solvents or additives should not be used to clean the probe connector. We would thereby
suggest to remove it from the dragster when cleaning the vehicle, to avoid probe pollution
caused by detergents.
REMINDER
: 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.
Attention: BOSCH LSU 4.9 Lambda probe has been designed to be used with
unleaded or diesel engines. It can be used with other kinds of engine too, but its
duration needs to be verified by the user with specific tests.
