LCU-One Lambda controller range of products allow you to perfectly tune the carburetion of your engine as well as keep it at its best, appreciably improving your car performances. All LCU-One lambda controllers use a wide band Bosch LSU 4.9 probe either for its capacity of saving the original calibration for its all life and for its duration: Bosch LSU 4.9 probe, in fact, has been designed to last for more than 100,000 km on a stock car.

LCU-One's can detect punctual Lambda value from 0.65 to 1.6, offering you an extremely precise measurement, very useful for engine tuning. Through the analysis of the remaining oxygen, LCU-One points out possible oxygen excess/lack in the carburetion, providing an essential information for 4 strokes engines: configurability of Stoichiometric ratio allows LCU-One to be used on petrol powered engines as well as on diesel or on alternative fuel (bio fuel, ethanol) powered ones.

Interface Options

LCU-One CAN Interface

Using the CAN Bus connection the LCU-One is easy to install, whilst multiple units can be connected for better engine control, one probe for each engine bank or even one probe for each engine cylinder.

The LCU-One CAN uses a Can bus and is easy to install, it configures Stoichiometric point and provides Lambda value and air / dual ratio and Lambda probe temperature and diagnosis. The product configures Stoichiometric point and provides:

  • Lambda value and Air/Fuel ratio
  • Lambda probe temperature and diagnosis

LCU-One Analog Interface 

Uses a serial line for programming and an analog output proportional to lambda value. To be even more user-friendly, LCU-One CAN & LCU-One Analog switch on/off together with the logger. It provides Lambda value and air/fuel ratio and thanks to the dedicated Lambda configurator software, LCU-One Analog allows you to configure:

  • Stoichiometric point
  • Analog output (0-5 Volt)


    • Wide Band Bosch LSU 4.9 Lambda Probe
    • Thread Iron Ring for Installation
    • 90 cm CAN Connection
    • Race Studio 2 Software
    • Dimensions: 80 x 37 x 15 mm
    • Waterproof: IP67
