The some ME ECU models features inbuilt Bosch Wideband control, meaning you can directly connect an LSU4.9 sensor to the ECU and it will give high speed, high accuracy lambda readings.


For the plug-in models, we offer a direct fit 2.5 meter cable along with genuine Bosch LSU sensor available from the web-store LOOM_PI_LSUKIT. The cable directly plugs into the Core at one end, and then into the LSU sensor at the other allowing a fast install time.


For the Wire-In variants you will need to hook up the 6-way wires to the ECU according to the ME442/ME360 wiring diagrams.


These ECU models feature an on-board BOSCH wideband controller. You can therefore directly connect an LSU 4.9 sensor to the ECU and have live, accurate fuel AFR readings.


It will also follow the guideline BOSCH heating strategies such that the sensors life is extended.


The below default tab shows the typical layout of the wideband settings. These should be left as default unless you are requiring different PID settings (which is rare).


Once configured, and warmed the status will report it is operating as normal. Int. WB AFR will then be reporting correctly. You can use this wideband signal as a reference for lambda control by selecting it under "sensor type" of the lambda settings (set it to Internal WB).


For best sensor longevity, the PID settings should be:


For Wire-Ins :

P=75

I=4000


For Plug-In ECUs

P=25

I=4000
