Total Control of Your Engine The LCU-One S controller allows you to perfectly tune the carburetion of your engine to keep it at its best and improve the engine's performance. Why Choose the LCU-One S The LCU-One S can detect an accurate Lambda value from 0.65 to 1.6, offering an extremely precise measurement, which is useful for engine tuning. Through the analysis of the remaining oxygen, LCU-One S points out a possible oxygen excess/lack in the carburetion and provides essential information for 2-stroke and 4-stroke engines. It uses a wide-band Bosch LSU 4.9 sensor, which is used for its capacity to save the original calibration for the duration of the sensor's life. In fact, the Bosch LSU 4.9 probe has been designed to last for more than 100,000 km on a stock car. LCU-One S Compatibility The Aim LCU-One S is designed to be compatible with a variety of vehicle types and motorsport applications — including race cars, motorcycles, motocross and kart racing — due to its compact, waterproof design (up to IP67) and its ability to integrate with Aim data systems via CAN bus. The configuration of the Stoichiometric ratio allows the LCU-One S to be used on petrol, diesel and alternative fuel-powered engines, making it adaptable to various engine configurations.
