MoTeC Lambda to CAN (LTC-NTK)

$395.00 – $650.00

$395.00
SKU: LTC-NTK
Description

MoTeC’s LTC NTK (Lambda to CAN) modules monitor, control and diagnose NTK Lambda sensors, transmitting readings on a CAN bus. When multiple LTC NTKs 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

  • NTK, 5 wire sensor

BASIC SPECIFICATIONS

Inputs/Outputs

  • 1 x NTK Lambda sensor (MoTeC #57007)
  • 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 at 1 Mbit/sec

Connectors

  • 1 x 4 pin male DTM connector (power/CAN)
  • 1 x mating connector for NTK Lambda sensor

Physical

  • Dimensions 38 x 26 x 14 mm excluding wiring looms and connectors
  • Weight 62 grams
  • Maximum ambient temperature 100 °C

Sensor Basic Specifications 

  • Maximum continuous operating temperature is 850 °C 
  • Maximum temperature for short period is 930 °C (maximum 10 minutes) 
  • Mounting torque 45 Nm max 
  • Lifetime estimates: 
    Sensor lifetimes are highly dependent on application. Typically sensor lifetime for high performance engines is 500 hours in unleaded fuel and 50 hours in leaded fuel. 
  • Fuel: Unleaded gasoline, ethanol gasoline blends, methanol, diesel, LNG, CNG, LPG 

The NTK UEGO (Universal Exhaust Gas Oxygen) sensor is a 5 wire wideband Lambda sensor. It is used to control fuel and ignition systems to optimize a car's performance in the areas of emissions and fuel economy. The Lambda sensors can be connected directly to any MoTeC ‘hundred series’ ECU with a Lambda upgrade enabled. It can also be connected via the PLM to any ECU or Dash Logger. Lambda gives a measure of the Air to Fuel Ratio (AFR) that is independent of the type of fuel being used.  

MoTeC ECUs allow for a Lambda aim table based on load and RPM. Referencing the measured Lambda, the Quick Lambda function in the software adjusts the values in the fuel control table at the specified load and RPM site to achieve the aim Lambda. Similarly, the Lambda Was function adjusts the values in the fuel control table using recorded Lambda measurements from a data log.
