Stock Oxygen Sensor Question
I'm curious if anyone knows where to find a data sheet on the stock O2 sensor. I'm working to perfect my LM-1 emu of the stock sensor and need to make sure it is outputting the correct (or as close to correct as possible) values for the PCM as it's giving me on the display and in HPTuners.
I am assuming the following: 14.7 AFR is 450mV
Slightly rich, say 14.1 AFR is 900+mV
and lean, say 15.1 AFR is <200mV
Can anyone tell me for certain what the stock O2 output curve looks like? I found this on Google but I have no real way to compare the lambda/AFR values from the LM-1 to the mV output of the LM-1.

I really don't want to have to find a torch and use different flames to figure out the curve on the O2 sensor. Can someone please point me in the right direction?
