Full Control Of Your Engine

The brand-new Aim LCU2 Lambda Controller has been developed to give drivers, tuners, and race teams complete control over engine carburetion and air/fuel performance. Designed for precision tuning across motorsport and performance applications, the LCU2 delivers highly accurate Lambda readings while introducing dual sensor capability for even greater monitoring and control.

Whether you're optimising power, improving drivability, or protecting engine reliability, the LCU2 provides the data you need to keep your engine performing at its best.

Why Choose the Aim LCU2 Lambda Controller

The Aim LCU2 accurately measures Lambda values, offering the precision required for serious engine tuning and calibration.

By analysing residual oxygen levels in the exhaust gases, the LCU2 identifies rich or lean carburetion conditions, helping you fine-tune fuelling for maximum efficiency.

With dual Lambda sensor support, proven Bosch wideband technology, CAN integration, and motorsport-grade reliability, the Aim LCU2 is the next evolution in air/fuel monitoring and engine tuning.

New Dual Lambda Sensor Capability

A major upgrade for the new LCU2 is the ability to connect two Lambda probes simultaneously.

This allows:

Monitoring of dual-bank or V-engine exhaust systems
Comparison between left and right cylinder banks
Greater fuelling accuracy across multiple exhaust outlets
Enhanced diagnostics and engine balancing
More precise tuning for high-performance applications

For race engineers and tuners, dual-sensor support delivers a significant advantage in both setup accuracy and engine safety.

Bosch LSU 4.9 Wideband Sensor Technology

The LCU2 uses the trusted Bosch LSU 4.9 wideband sensor, selected for its long-term precision and stable calibration retention throughout the sensor’s service life.

Engineered for durability, the Bosch LSU 4.9 probe is designed to last for over 100,000 km under standard operating conditions, giving you dependable performance session after session.

Precision, Reliability & Fuel Flexibility

The configurable stoichiometric ratio allows the LCU2 to be used across a wide range of fuel types, including petrol, diesel, ethanol blends as well as alternative performance fuels.

This flexibility is what makes the LCU2 suitable for road, race, track day, karting, motorcycle, and specialist engine applications.

Seamless Aim Integration

The LCU2 integrates directly with Aim data logging and dashboard systems via CAN bus, allowing Lambda data to be viewed live, logged during sessions, and analysed afterwards alongside other critical engine parameters.

This enables deeper insight into:

Fuel mixture behaviour
RPM and throttle relationship
Gear-based fuelling trends
Temperature and pressure correlation
Performance consistency lap after lap
