i am not 100% sure if i am tunning my AFM tables correctly . not sure if i am changing the right G/S numbers. would really appreciate some help.

Hey Alex,

I would start by adjusting your AFM by +3 on 0-10 g/s and +5 on 10.01-60 g/s
Upload, datalog and fine tune it by adjusting into small g/s clusters.

for example i start with 0.52 all the way to 10... +3

Yes, highlight all cell on that range and adjust by +3.

Thank you I did a data log this morning I will post it later on today. I am still unsure how to read the graph should I be looking at the line in the middle that varies or should I be looking at the red spots? I'm not too sure what you mean by fine tune it by adjusting into small g/s clusters.

To clarify adjust by percent (ie: +3%). Usually make half the desired change and retest.

The +3 is rough estimate of the average you need to trim in the AFM from the given range. See how the car reacts to this and re test. From there you may calibrate your AFM by smaller clusters.

The blue line represents the median average of all the little red marks. If it is a strong cluster of a bunch of data points use the line reference. If its sporadic little ones (unless a small cluster are together) then use your best judgement. Essentially the more data points make the blue line more accurate of a suggestion.

Dont look at the red dots or you will go crazy lol!

the drive feels better but my LTFT is high now

You are still running lean. Adjust 0 g/s - 10 g/s by +3 and 10.01 g/s onwards by +4.

Goodluck!

I'm trying to understand if I am still running lean why is my LTFT showing I am running rich .

following the blue line from g/s 0-about 14 showing i am running rich about -3
