The Bosch LSU 4.9 sensor is a 5 wire wideband Lambda sensor. It is used to control fuel and ignition systems to optimize a car's performance in the areas of emissions and fuel economy. The Lambda sensor can be connected directly to any MoTeC ‘hundred series’ ECU with a Lambda upgrade enabled. It can also be connected via the PLM to any ECU or Dash Logger. Lambda gives a measure of the Air to Fuel Ratio (AFR) that is independent of the type of fuel being used.
