The Aim LCU ONE CAN Lambda Controller range of products allow you to perfectly tune the carburetion of your engine, 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.

Full Control of your engine

The LCU ONE CAN Lambda Controller 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.
