Gentlemen, what is the correct parameter to record in Techstream to get my Air/Fuel Ratio?

 

anyone know the answer to my question?

What parameter do I need to select to read my air fuel ratio?

 

Pretty sure it's in the engine data tables.

 

You probably want to look for O2 Feedback, WB (Wideband) if that is what we have, I'm not sure if it's narrow or wideband, but usually OEM cars come with Narrowband O2 sensors which are pretty stupid and have a much narrower range of ratio.

 

Correct^^^we need wideband sensor for proper feedback on tuning. I know Rafi said that if we (up here at altitude) had a wideband hooked up he could tune our cars more directly to our specific altitude. Maybe one of us will get one and have it welded in for logging purposes, but that's still to remain on who is going to do it first?

 

I'm definitely going to do this, but I am in Florida. Also, the car has a half wide band lol, it maxes out lean(idk at what value) or rich if it goes passed 12.0 afr.
