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.


Two variants for all your needs


Uses a CAN bus and is extremely easy to install.

The product configures Stoichiometric point and provides:

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

LCU-One Analog

Uses a serial line for programming and an analog output proportional to lambda value. To be even more user-friendly, LCU-One CAN and LCU-One Analog switch on/off together with the logger.

The product provides Lambda value and Air/Fuel ratio and - thanks to the dedicated Lambda Configurator software, LCU-One Analog allows to configure:

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