MoTeC's LTC (Lambda To CAN) monitors, controls and diagnoses a Bosch LSU 4.9 Lambda sensor, transmitting Lambda readings on a CAN bus. When using multiple LTCs, up to 32 Lambda sensors can be configured on a single CAN bus for simultaneous monitoring by an ECU or logging device.

A MoTeC gateway device is required to communicate with the LTC on CAN. Such devices include:

• M1 Series ECUs
• All C Series Display Loggers, ACL, ADL3, SDL3, CDL3
• UTC (USB to CAN) #61059

For multiple installations, LTC Manager software allows all units to be simultaneously managed and diagnosed.

The software is used to:

• Configure and calibrate all units on the CAN bus
• Display readings and diagnostics
• Configure CAN transmission addresses
• Control free air sensor calibration
• Update unit firmware

MoTeC LTCs come pre-configured to suit a single LTC unit installation. By default, the initial factory sensor calibration is used and the CAN address is 460.

It is only necessary to use LTC Manager if installing multiple LTC units, or if changes to the default settings are required.

All dimensions in mm.

To power the LTC, connect to either the ignition switch for fast sensor startup or the fuel pump relay to prevent accidental battery drainage.

Wiring example

For information on wiring a CAN bus with several LTCs and any number of other CAN devices (as per the example), refer to the relevant device manual.
