AiM LCU-ONE Lambda Controller with Bosch LSU4.9 Wideband
Add Air/Fuel readings to your AiM dash/logger
Lambda "Controller" reads exhaust air:fuel ratios with a Bosch Motorsport LSU4.9 wideband O2 sensor (included). Integrate air:fuel readings into your data overlay easily and seamlessly. This is sold per sensor, so order two if you plan to read both engine banks.
The AiM Lambda setup will detect values from 0.65 to 1.6 (9.5-23.5 AFR). The Bosch LSU4.9 sensor is actually an OEM sensor used by many manufacturers for precise air:fuel monitoring. It's one of the most-advanced and reliable wideband sensors available on the market. Sensor and LCU module are connected via Bosch 6-pin plug and replacement sensors are readily available. A weld-in bung is not included and must be sourced separately (nearly any exhaust shop will have them on hand). The LCU requires a hardwired switched power source. The power cable is included with spade connectors.
Air:fuel data is transmitted to your AiM Data Hub, dash, or logger via a AiM CAN 5-pin cable (not included). CAN cables are sold by length so you can keep your wiring neat and organized.
The LCU has three output options:
AiM CAN: direct connection to an AiM dash, logger, or Data Hub with AiM 5-pin CAN cable (sold separately)
Analog: uses a 4-pin Binder connector with RS232 protocol to wire into an ECU or AFR gauge.
Combined CAN & Analog: both types are included on the same harness.
Also available without the Bosch LSU4.9 if you can source your own (inquire).
