Part No: #61300L

OVERVIEW

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.

FEATURES

Provides accurate Lambda measurement, even when exhaust gas temperature is changing rapidly (heating or cooling).
Calibrated by the user for a particular sensor using either the initial sensor factory calibration or the free air calibration.
Pre-configured to suit a single unit installation. If necessary, the configuration can be adjusted; see the Configuration section for more details.
Units marked with a 2 or higher under the barcode are able to transmit extended Lambda values (Rich Lambda).

COMPATIBILITY

MoTeC ECU: M1 Series, M84, M400, M600, M800, M880

MoTeC Display/Loggers: All C Series Display Loggers, ACL, CDL3 (and discontinued models: SDL, SDL3, ADL, ADL2, ADL3)

PC COMMUNICATIONS

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

SPECIFICATIONS

Inputs/Outputs

1 x Bosch LSU 4.9 Lambda sensor
Power supply voltage 11 V - 16 V
Power supply current 110 mA typical plus the sensor heater current. Heater current is typically 0.5 A - 1 A and up to 2 A on startup.

Communications

1 x CAN - using LTC Manager, configurable to:
125 Kbps, 250 Kbps, 500 Kbps or 1 Mbps

Physical

Dimensions: 38 x 26 x 14 mm, excluding wiring looms and connectors
Weight: 78 g
1 x 4 pin male DTM connector (power/CAN)
1 x mating connector for Bosch LSU 4.9 sensor
Maximum ambient temperature: 100 °C

SOFTWARE

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

CONFIGURATION

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.

DIMENSIONS AND MOUNTING

All dimensions in mm.
