I'm trying to fix a bad problem with pinging when I punch it at low rpm (around 2K). Don't have a wb hooked up, but have efilive, and have logged o2 voltages. Mapping it by VE cells, in the problem cells the o2 voltages average around .4, with the max readings in the .7 - .84 range. So even just using the max readings, is that too lean? This is with MAP in the 75 - 85 kpa range, RPM in the 2000 - 2400 range. The cell counts are high enough that I believe the numbers are accurate.

.890 give or take .100+\-. but are you looking at the scanner? or a csv? it's kinda impossible too to put a finger on it with the scanner . move it to a spread sheet.

That is too lean if you are going WOT. Ricken it up to around .900 or richer at WOT.

I'm looking at it in a map in efilive, so it's like a spreadsheet with the same row/columns as the VE table. So each "cell" has the average STFT value over the number of times it hit in that cell.

Guess I should just try the SD tune thing first. Just wondering how far off these values are.

don't know much about efi live i use tuner cat w\mx scan it updates real fast 7 or 8 times a second in csv. it gives a clear view in real time. does efilive have an option in there scanner to put it into excell or cvs? does yours give you a time stamp,or run time?
85kpa should be in pe .880-930 range +.900 on a punch is more like right. not like my shoot from the hip answer. yes brad your right. but that should be pe 15 cell?
look at a csv post it up. i'm a noobe to this tuning thing but the learning curve is a lot less the more we help each other

Dude you are almost there why not get the WB and really know what you are getting? "Tuning" with LTFTs=Magic Beans.
