MoTeC LTCD - Lambda to CAN Dual

Description

MoTeC LTCD - Lambda to CAN Dual
OVERVIEW
MoTeC’s LTC (Lambda to CAN) modules monitor, control and diagnose Bosch LSU 4.9 Lambda sensors, transmitting readings on a CAN bus. When multiple LTCs 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.
Sensors compatibility
•Bosch LSU 4.9, 5 wire sensor

FEATURES
General 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 a free air calibration
•Install as a single unit or in multiples
•Pre-configured to suit a single LTC unit installation
•Cost effective
Measurement/Configuration

-gasoline/petrol-alcohol
-LPG
-diesel
-user defined 'blend' fuel
•Comprehensive diagnostic and status channels
•Calibration methods:
-automatic, using the sensor's built-in calibration resistor
-known oxygen environment
•Standard configuration tables
•Configurable to compensate for sensor aging and contamination
•Accuracy +/– 1.5%
•Operating range:
-Lambda 0.65 to 10

SOFTWARE
LTC Manager Software
For multiple LTC/LTCD installations, LTC Manager software allows all units to be simultaneously managed and diagnosed.
Note: MoTeC LTCs come pre-configured to suit a single LTC unit installation in which case the use of LTC Manager if not required.
•The software is used to:
-configure and calibrate all LTCs on the CAN bus
-display readings and diagnostics
-configure CAN transmission addresses
-control free air sensor calibration
-update LTC firmware
