Lambda Sensor Bosch LSU4.9
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.
Maximum continuous operating temperature is 930 °C
Maximum temperature for short period is 1030 °C (maximum 10 minutes)
Mounting torque 60 Nm max
Lifetime estimates: Sensor lifetimes are highly dependent on application. Typically sensor lifetime for high performance engines is 500 hours in unleaded fuel and 50 hours in leaded fuel. See also Sensor lifetime page 4
Fuel: Unleaded gasoline, ethanol gasoline blends, methanol, diesel, LNG, CNG, LPG
