Default Which do you log? LTFT or LTFT Avg

Well, there are two sets of LTFT's in EFI LIve. I am not sure if they are in Auto Tap off the top of my head but can someone set me straight here.

I used the LTFT to adjust my MAF table in edit to get negative LTFT.

Should I have used LTFT Average instead?

Thanks for any help.

IIRC, the average parameter is a weighted average. This is what I tend to do with the other parameter anyway. The biggest difference would be that you know exactly how the average is arrived at if you compute it yourself.

I'd suggest that for the purposes of ensuring the LTFT for the FTC you're in before going to WOT is < 0, looking at an average is not all that useful. It hides outliers which are what you really want to know about. Or you can be heavy handed and make sure everything is "negative enough." <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

If you don't already know which FTCs matter more when thinking about WOT tuning you can look at the FTC/LTFT data as time series data.

Thanks. I will use the LTFT for my tuning purposes.

I always average the column so I will have my own LTFT AVG if I want/need it.
