LTFT log help After doing some logs this morning, I am getting large negative numbers. I have been averaging my fuel cells 4-16 and throwing out the large numbers. Is this normal, or is there a problem that I am missing? My csv file

Re: LTFT log help Not sure about the big bumps(-95)as I have never seen that but if you remove them your averages are around -4.5 which is not all that bad. You may want to try the F setting which is 5% lean and give it another go after approx 30-45 min of drive time to let it settle.

Re: LTFT log help I am having the same problem. I was all good a few months ago. Got out ATAP a few days ago to see how the car was doing and now I am getting -100 or more spikes every couple seconds. Other than that my LTFT averages are slightly neg. It's almost like it is getting a bad frame from the OBDI or ATAP... ? I am going to try and follow this up with the manufacturer.
