AiM LCU2 Lambda Controller — Wix Product Description
Precision Air/Fuel Ratio Monitoring for Maximum Engine Performance
The AiM LCU2 Lambda Controller is a professional motorsport air/fuel ratio monitoring system designed to provide accurate lambda readings for engine tuning, performance optimisation and reliability monitoring. Developed for racers, tuners and performance enthusiasts, the LCU2 delivers fast, precise data to help achieve optimal combustion and maximum engine efficiency.
 
Using advanced Bosch LSU 4.9 wideband sensor technology, the LCU2 continuously measures exhaust oxygen content to identify rich or lean fuel mixtures, allowing precise fuel mapping and engine calibration across a wide range of applications.
 
Dual Wideband Sensor Capability
A major advancement of the LCU2 is its ability to support two Bosch LSU 4.9 lambda sensors simultaneously. This makes it ideal for V-engine configurations, dual exhaust systems and applications where monitoring individual cylinder banks is critical.
 
Benefits include:
Dual-bank air/fuel monitoring
Improved engine balancing
Enhanced tuning accuracy
Better diagnostics and fault detection
Increased engine protection under load
 
Accurate Lambda Measurement
The LCU2 measures lambda values with exceptional precision and rapid response times, making it suitable for both dyno tuning and live vehicle monitoring. It supports a wide range of fuel types through configurable stoichiometric ratios, including:
Petrol
Diesel
Ethanol blends
Methanol
Alternative performance fuels
 
This flexibility makes the LCU2 suitable for road cars, race cars, motorcycles, karting and specialist motorsport applications.
 
Seamless AiM Integration
The LCU2 integrates directly with AiM dash displays, loggers and data acquisition systems via CAN bus communication. Lambda data can be viewed live on compatible displays, recorded during sessions and analysed afterwards using Race Studio software.
 
This allows detailed analysis of:
Air/fuel ratio trends
RPM and throttle position correlation
Gear-specific fuelling behaviour
Temperature and pressure relationships
Overall engine performance and reliability
