Precision and reliability

LCU1S Open can detect accurate Lambda value from 0.65 to 1.6, offering an extremely precise measurement, very useful for engine tuning. Through the analysis of the remaining oxygen, LCU1S Open points out a possible oxygen excess/lack in the carburetion and provides essential information for 2 strokes and 4 strokes engines. The configuration of Stoichiometric ratio allows LCU1S Open to be used on petrol, diesel and also alternative fuel powered engines.

lt uses a wide band Bosch LSU 4.9 sensor that saves the original calibration for the duration of the sensor's life.
In fact, Bosch LSU 4.9 probe has been designed to last for more than 100,000 km on a stock car.

HOW IT WORKS

LCU1S Open allows you to transmit the data via CAN to every system: configuring the output is very flexible, by setting IDs, messages, baud rate and frequency.

Flexible Expansion

LCU1S Open can also be used as an AiM Expansion, without any issues or limitations thanks to the optional cable: CAN AIM for Open Products.
