MoTeC’s LTCD (Lambda to CAN Dual) modules monitor, control and diagnose Bosch LSU 4.9 Lambda sensors, transmitting readings on a CAN bus. When multiple LTCDs are used, up to 32 Lambda sensors can be configured on a single CAN bus, allowing an ECU or logging device to simultaneously monitor numerous Lambda sensors.
