logging question

[streetsoldier60]

okay so i don't know if this has been asked or not...done a lot of reading on here but still haven't seen what i'm quite looking for. so please don't rip my head off just curious! . so when you are logging with palm n stein...i'm using the rom for laptops but anyways the o2 readings give your your a/f ratio at least upstream one does im aware of that but is that real time like a wideband shows you or no? is it still narrow band? thanks for the help.

on 2gs i log the STFT and LTFT fuel trims you want to keep them as close to zero as possible the 02 voltage should be right around 93 at WOT if i remember correctly its been a while since i used palm and the o2 still reads narrow band if that helps you any

Yes it's still narrow band, unless of course you have a wide band o2 sensor. If by "real time" you mean what is happening when the logger sent the request for the data, then yes. It does log real time A/F ratio's. The thing with the narrow band is that they aren't accurate enough to be worth the time to try and tune with. Your talking about a 1 volt sweep. I do not recommend using the factory, or any other narrow band o2 sensor for tuning. When I tune cars on pump gas and take my WB back out, the factory narrow band usually see's around 0.87 to 0.91 volts on WOT pulls. Again I do not recommend using the narrow band o2 sensor for any tuning.

hey that is exactly what i needed to know. thank you guys much. and yes I will be looking into buying a wideband 02 and guage here in the near future so between the logging the wideband and the safc i should be able to do some decent tuning for the time being..anyways thank you much everyone for the insight! -Dan
