Ready to make adjustment, please verify.
Well 2017 Camaro SS. Until I get my bung welded in for my wideband i just setup my tune for MAF tuning. I logged MAF freq, and STFT since I don't have a wideband yet. Ok so I took StFT1 + STFT2 and divided those by 2 for the average. Now what do I apply those too? Should I go the MAF table and multiply the averages of SFTF by half and add that percentage to the table? MOst of the STFT numbers are negative.

Ok correct me i am wrong but ltft is an average of stft over time so if i filter the stft to take the average and i have 1000 hits is that the same?

Last question, for now lol. So if the fuel trim is - that means its pulling fuel to hit lambda, correct? So in a case with - fuel trim i would be subtracting from the maf table?

Josh is correct. If LTFT is enabled then you log MAF vs LTFT. It has the final say so in trimming fuel.
Far as the paste special feature, The only time I do the full multiply is if it's the first revision and the trims are way out +/-10%. Once in the single digits I only multiply percentage by half.
