    Log_0029.efi Can you check this log for me? Ive been logging STFT and LTFTs and im a bit confused, if i look at the min and max numbers rather than average it swings from -14% to +14% in some areas. i dont see how this is logical

    If you look where STFT peaks and drops you will see LTFT get a small adjustment... this is how it is supposed to work

    thats not what i am talking about. i made maps for ltfts and stfts based on map and engine rpm. you can view cell counts, average and min/max values. checking the minimum and maximum values my trims vary from -14 to +14 in some areas in a single 20 min long. doesnt seem right for it to be adding 14% in one spot at the beginning of a long and then removing 14% 10 min later.

    i spent alot of time yesterday adjusting the VE table, i have the maf turned off, and as of last night my "average" logs were looking good, i fine tuned the VE one more time then drove it today and noticed it pulling alot of fuel in certain areas and adding alot of fuel in others. when i checked the average numbers it didnt reflect what i watched as i drove so i checked the min and max values and i was really confused. thats alot of fuel to be removing then adding all in 20 mins of driving

    Hmmm... a large variation...

    If there is that much variation in a single log (a fairly short time period) then there's something going wrong someplace (maybe physically, like airleak or rail pressure)...


    Let me look thru Log_0029.efi in more detail.

    yeah it didnt make much sense to me either. its no wonder i cant seem to make this thing happy. one thing ive noticed is my check engine light does not work sometimes after flashing my ecm, is that normal?
