HINT-LAMBDA

There are three factors to consider when choosing Lambda measurement equipment:

  • Purpose

    • Narrowband Lambda measurement for emission control

    • Wideband Lambda measurement for accurate tuning

  • Lambda Sensor

    • Narrowband—Ford
    • 5 wire wideband—Bosch LSU
    • 5 wire wideband—NTK UEGO

The Bosch LSU 4.9 Wideband Lambda sensors can be connected to an LTC or LTCD unit to transmit the values on CAN. The LTC is the singular version that connects to one Lambda sensor, while the LTCD, the dual version, connects to two Lambda sensors.

Up to 32 Lambda sensors can be connected on the one CAN bus using numerous LTCs, LTCDs or a combination of both. They are compatible with any current MoTeC Dash, Logger, 'hundred series' or M1 ECU.  The can also be used (in conjunction with a UTC) as a standalone solution with a PC, for example on a dyno.

Wideband Lambda sensors can be connected to the PLM—a stand-alone Lambda meter with integrated display—which transmits the data via an analogue voltage output or via CAN communications. The PLM uses the 5 wire sensor technology.

The PLM can be used to connect a 5 wire technology sensor into an ADL3, SDL3, ACL using the CAN Bus.  or earlier generation ECU through an AV input.

On the data loggers, 'hundred series' and M1 ECUs the number of Lambda measurement inputs can be extended by connecting multiple PLMs to the CAN bus.

Wideband Lambda sensors can be directly connected to an ECU omitting the need for an external Lambda amplifier. This requires the wideband Lambda upgrade to be enabled in the device.

    • the 'hundred series' ECUs are capable of using 5 wire sensor technology
    • the earlier generation ECUs use the 4 wire sensor technology
