Autotap DETAILED LTFT/O2 spreadsheet template here...
I modified it to break LTFTs out by fuel cell, including counts and individual averages. I've found that tuning your fuel trims to zero can be skewed by some of the low-speed/low-load cells, and have had very good results looking at the 'big picture.'
Dump your Autotap log file into the template and save as an .xls, everything you need is embedded in the file.
