Deadtime affects idle more than anything...
ecmlink101datalogging [ECMTuning - wiki]Well to be honest I'm not sure how to log my wideband. I dont see it in the list so i guess I'll need to do some more reading and see if I can figure it out.
The reason my switch point is set to 2.45 is because according to the ECM WIKI for an LC1 WB the switch point should be 2.44... Either way i guess its wrong. Which is correct 2.49 or 2.44?
http://ecmlink.com/wiki/v3narrowbandsim said:The best way to determine your own switch point is to datalog the wideband kit while running closed loop off a stock narrowband sensor and then simply take an average of the raw wideband voltage (available in the datalog as a Raw value) while the narrowband sensor is cycling normally.
Ok I may have found a giant issue here...
I'll do as you suggest and get another log posted tomorrow.
It looks okay to me, although I'd bump the switch point to 2.47v (based on log 3)...The o2 is cycling but it looks kind of strange based on what I have seen on other logs.

Well, I think it's safe to say that your o2 is cycling now...perhaps mark as resolved?

I also noticed my BOV is venting a small amount of air at idle.
You should be logging more values:
