MoTeC's LTCD (Lambda To CAN) is a dual sensor version of the LTC. It monitors, controls and diagnoses two Bosch LSU 4.9 Lambda sensors, transmitting Lambda readings on a CAN bus. When using Dual LTCs, or a mix of singular and Dual LTCs, up to 32 Lambda sensors can be configured on a single CAN bus for simultaneous monitoring by an ECU or logging device.

  • 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).
Inputs/Outputs
  • 2 x Bosch LSU 4.9 Lambda sensors
  • Power supply voltage for each sensor: 11 V - 16 V
  • Power supply current for each sensor: 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
