LCU Lambda Controllers series

LCU Series

The Lambda controllers smaller, lighter and faster.

LCU Series is proposed in two version, AiM Expansion or Open version to be connected to every device.

LCU Lambda Controller series,
precision and reliability

LCU Lambda Controller Series allows you to perfectly tune your engine’s carburetion, keeping it at its best and improving performance.

The controllers 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, the controllers points out a possible oxygen excess/lack in the carburetion and provide essential information for 2 strokes and 4 strokes engines.
The configuration of Stoichiometric ratio allows LCU Series to be used on petrol, diesel and also alternative fuel powered engines.

The LCU2 versions featuring two sensors are ideal for V-type and inline engine with dual exhaust manifold configurations.

LCU series allow precise monitoring of air-fuel ratios through wideband Bosch LSU 4.9 sensors, providing accurate combustion data to optimize the power curve and improve engine tuning. Reliable Lambda data help prevent engine damage and ensure optimal performance under all operating conditions.

In fact, Bosch LSU 4.9 probe has been designed to last for more than 100,000 km on a stock car.

OPEN VERSION

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

LCU Open versions can also be used as an AiM Expansion, without any issues or limitations.

CAN OUTPUT

LCU Open versions allows to build a CAN Output on RaceStudio 3 to communicate with external devices. You can set bit rate protocol, field messages and CAN payload details.

With the Lambda Multiplier Manager it is possible to customize the stoichiometric air fuel-ratio or choose to use the pre-defined default value.
