If I run an AEM gauge can it input into the ECU to help with tuning etc?
If you plan to use as analog input, i can share how to modify the board. If it is can connection then it just config.For board mods i need the board revision.
Maybe this will also help you

Thanks for the input lads, I think I will get myself an AEM gauge and hook it up rather than sending the board away etc.

Ooooops that's my mistake 
We need to either ship you the chip or ship your board for modification. I believe you are in Ireland? I would need Alex to help he is in EU as well.
Yes, i can help, but we need feedback how should we do it, i send it out or i can rework the board.We need to either ship you the chip or ship your board for modification. I believe you are in Ireland? I would need Alex to help he is in EU as well.

Next to the wbo connector there should be a mosfet bts3028 that would enable sensor heater circuit.

You are responsible for the green wire from ECU to female plug. Until I see a picture of your green wire between ECU and female plug there would be nothing else for me to do here.
Calibration resistor is inside the male plug on the sensor assembly. Because calibration resistor is inside the male plug there are only five wires between male plug and actual sensor.

Feel free to not provide requested info. Feel free not to post picture of how you wired things. Feel free not to clarify how you dealt with sensor male plug and harness plug.
Originally I did cut plug off and wired my own male and female plug but was advised I needed the original Bosch connector so I wired it back on. I purchased a female connector for the Bosch plug and then wired it exactly as per the diagram above from the wiki. Only wire I don't have is the green one.Statistics: Posted by ML190E — Thu Mar 17, 2022 1:48 pm

I've followed the wiring diagram on the wiki to wire the sensor to the wideband output on the board, with Jimmys guidance I have enabled the rusEFI can Broadcast and I have also enabled can wideband under EGO sensor. The only wire I don't have is the RCal as my sensor only has 5 wires and not 6 but Jimmy feels I do not need this
The air/fuel ratio gauge is still not giving me a reading so that I can start to tune
Is there something else I need to do? Or is that 6th wire the missing piece that i do need
