LCU-ONE CAN connected to MyChron4 660 User Manual introduces the LCU-ONE features and its connection to MyChron4 660. It also describes how to view data on MyChron4 660.
The LCU-ONE CAN is a lambda controller unit designed for BOSCH LSU 4.9 wide‑band probes, supporting petrol, diesel, methane and alcohol‑based engines. It provides lambda (air‑fuel ratio) values to the MyChron4 660 gauge via the CAN bus and manages probe heating to keep the sensor within its optimal temperature range.
The manual covers mounting the controller, wiring, probe installation, connection to the MyChron4 660 (directly or via a data hub), visualization of lambda values on the gauge, and includes part numbers and technical drawings. Safety precautions, fuse recommendations, and diagnostic messages are also described.
| Lambda detection range | 0.65 to 1.6 (free air) |
|---|---|
| Probe operating temperature | around 700‑800 °C (1292‑1472 °F) |
| Maximum probe temperature | 900 °C (1652 °F) |
| Recommended fuse | 10 A |
It should be installed in a flat location away from heat sources, using the supplied bracket, with wiring kept clear of heat and the probe mounted on the exhaust pipe using the provided adaptor.
Connect the controller directly to the MyChron4 660 back connector labelled EXP/PC, or via a Data Hub CAN multiplier; the system will automatically recognize the peripheral at startup.
