Aim LCU-ONE CAN User Manual

About this manual

The LCU-ONE CAN is a lambda controller unit designed for wide‑band BOSCH LSU 4.9 probes, supporting petrol, diesel, methane and alcohol‑based engines. It transmits air‑fuel ratio data to MyChron4 via the CAN bus and manages probe heating to keep the sensor in its optimal temperature range.

The manual provides step‑by‑step instructions for mounting the controller and probe, wiring, connecting to MyChron4, configuring temperature channels, visualising data, and includes part numbers and technical drawings for the harnesses.
