Hi Steve,
I reread the ALM board manual:
I guess I missed the second part :)
So to keep it simple, maybe a relay powered by the oil pressure
switch?
Or what input do you use for that for your CoPilot?

Hi Finn
Sounds like you use the same ALM board as me. All I recall is reading that you need a genuine Bosch, but not sure if that was simply sales talk.
I switch mine on manually a few moments after startup as per their instructions to avoid damaging the sensor.
I’m just in the process of building a micro I call CoPilot to manage a few things for me. One is the Wideband switch on after start.
Cheers

I now have about 100 engine hours on my Bosch LSU 4.9 wide band oxygen sensor with the Ecotron ALM-Board (0-5V output).
Recently I've seen the output intermittently drop to 0 volts. So I replaced the sensor with one I bought on eBay a couple if years ago. (0258017025 WideBand O2 Oxygen Lambda Sensor LSU 4.9 for PLX UEGO AEM 30-2004 New).
Well, that doesn't work at all. The ALM-Board outputs zero volts all the time.
Anyone have experience with the Bosch LSU 4.9 oxygen sensor?
Are there versions with different pin-outs but same part number (0258017025)?
