Not trying to hijack or change course here...
We have multiple cars and each has a bung installed for the WB sensor. I use an Innovate LM2 for the stuff. I like that I can plug it onto my carbed cars as well as the later lear cars. Does all kinds of data logging, etc. I picked up a cheap TPS and put it on a little bracket to measure TP on the old carby cars just for a data point. Kinda geeky but adds fun and info.
Just another device for you consideration if you own multiple cars.
