MoTeC Lambda to CAN Dual NTK

Details

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

NOTE: MoTeC’s LTCD NTK is also available in a singular version, LTC NTK

Frequently Asked Questions About the MoTeC Lambda to CAN Dual NTK

What is the main advantage of the MoTeC LTCD NTK?

The LTCD NTK allows you to connect two NTK Lambda sensors to your ECU or logger using a single CAN bus connection, simplifying wiring and improving accuracy.

Can I use Bosch sensors with this specific module?

No, this version is specifically designed and calibrated for NTK Lambda sensors. For Bosch LSU sensors, you would need the standard LTC Bosch version.

How many Lambda sensors can I monitor on a single CAN bus?

By daisy-chaining multiple LTC or LTCD units, you can configure and monitor up to 32 separate Lambda sensors on a single CAN bus.

What is the difference between the LTC and the LTCD?

The standard LTC is a singular version controlling one sensor, while the LTCD (Dual) is capable of controlling two sensors from one module.

Why is CAN bus transmission better for Lambda readings?

Transmitting digital data via CAN eliminates the signal degradation and electrical noise often found in long analog wiring, ensuring more precise tuning data.
