Show original supplier description
The Link ECU CAN Lambda Kit (CANLAM) is an easy-to-use CAN module that provides digital wideband sensor control via CAN bus, making it compatible with leading aftermarket ECUs. This system is essential for accurately tuning fuel mixtures by measuring the proportion of oxygen in exhaust gases, and it allows your ECU to make real-time tuning adjustments. The module features a powerful Bosch LSU 4.9 sensor and its fully digital design eliminates the signal loss, risks, delays, and errors associated with analog alternatives. Additionally, the CAN Lambda never requires free air calibration. This kit includes the CAN Lambda device, a Bosch LSU 4.9 sensor, a Deutsch 4-Way Connector Kit, an O2 Bung and Plug, and stickers. The enclosure dimensions are 60 x 26 x 15mm with a lead length of 170mm. The controller requires an input voltage of 7.5 - 20 V and draws 100 mA, while the sensor operates between 10.8 - 16.5 V and its heater draws 8 A. The operating temperature range is -20 to 100 degrees Celsius, with a sensing range of 0.67 to 10 lambda. The CAN frequency can be set to 1Mb/s, 500kb/s, 250kb/s, or 125kb/s. For users employing the CAN Lambda with a G4+/G4X PlugIn ECU, a Link CANPCB cable is required to access the CAN port on the PlugIn PCB, along with a Link CANF field insertable CAN plug. It is important to note that the Bosch LSU 4.9 sensor included in this unit is sold exclusively for aftermarket use. As Bosch's warranty specifically excludes aftermarket applications, no warranty is provided on the LSU 4.9 Sensor itself. The manufacturer recommends following proper CAN protocol and provides a QuickStart Guide and a full manual for detailed instructions.
