Hi Steve,

I reread the ALM board manual:
<dncbiflahgfcdcla.png>= ;
<ojbfbooeieolhjmj.png>= ;

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

I switch mine on manually a few moments after startup as per their =

I=E2=80=99m 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.

Anyone have experience with the Bosch LSU 4.9 oxygen sensor?

Are there versions with different pin-outs but same part number =
