The Bosch LSU 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, power or fuel economy. The Lambda sensor can be connected to M1 ECUs using an LTC - (Lambda to CAN) PLM - (Professional Lambda Meter) Dash/Enclosed Logger Hundered series ECUs with a Lambda upgrade enabled Lambda gives a measure of the Air to Fuel Ratio (AFR) that is independent of the type of fuel being used. MoTeC ECUs allow for a Lambda aim table based on load and RPM. Referencing the measured Lambda, the Quick Lambda function in the software adjusts the values in the fuel control table at the specified load and RPM site to achieve the aim Lambda. Similarly, the Lambda Was function adjusts the values in the fuel control table using recorded Lambda measurements from a data log. MoTeC SKU 57005
