Widebands that connect via serial->USB for logging are using the WB's serial output, not the WB's analog 0-5v output.
The EGR pin will read an analog 0-5v signal, like from a pressure transducer, directly, with no adapters connected to converters connected to some other thing that connects to something else.
Pins 2 and 5. The same two that are used for the WBO2 when you go from a serial to USB adapter.

I have never looked at the signal coming out of the USB cable from the WBO2, I assumed those like AEM were converting it to a 0-5v analog signal and then assumed a basic 3 wire transducer is already giving a 0-5v analog signal and therefore could feed it directly into the USB.
That's why I am asking for clarification and help understanding it.
