Where are the serial PIDs expressions?

Where can I find the serial PIDs expressions?
I looked in the sae_generic.txt and only found serial BENs.

Thinking about this....

The serial data is already in "lambda / AFR", so there is no need to actually "calculate" the values from an analogue voltage. the only thing needed is to "interpret" the serial data to extract the needed values. So there will be no "calculation" in sae_generic.txt. Instead, think of the serial WB controller as an additional "controller" that the V2 talks to. Much like "Engine RPM" or "Commanded AFR", the V1/V2/AC just reads the required data directly from the controller and interpreters the data directly as a value.

The BEN factors on the other hand need to be calculated as the first place that 'Commanded AFR" and "Serial WB AFR" are seen in the same place is the log file.

Looking at one of my logs 1Lambda = 14.7AFR+/-
I wanted to see if there was a way to change this to match {B3601} 14.6AFR
I guess it's easier to change 1EQ to 14.7AFR

Or look at the config in the WB controller. I know that the TechEdge allows you to set the expected stoich point in the firmware. Just hook it up to the laptop via a serial port and send the commands using the supplied software. You can set stoich as any value you want and the serial data is then referenced to that.
