Use Post Cat o2 channels for WBo2 and MAP

I am planning to use the rear lambda channels to bring WBo2 and MAP into the datalog for seamless tuning/no additional hardware. I forget if we can see raw lambda voltage through ds2 datalog or is it a calculated value. I will play with it tonight.

Has anyone used their rear o2 sensor channels to bring accessory information into their RR datalogs with the ms42 yet?

Did you ever get anywhere with this?

I haven't. I have been logging WBO2 through serial into RR. It works great but is cumbersome to plug in 2 usbs.

However I am running 1 Pre-cat o2 and no post cat o2 configuration now so perhaps I can use a primary o2 channel for faster logging of a MAP sensor. Though I am thinking it might throw a code because it seems even if you change the configuration, you must disconnect the sensor so MS42 will ignore it.

What config setting are you using?

(0) One pre-cat lambda sensor or cat preparation

It should only learn pre-cat bank 1 sensor is equipped or not.
