What in the Hell am I doing wrong with SD Tuning??? I logged a 40 min run normal driving ,speed up ,slow down,rev motor at lights ect...I copied my Histogram to my VE Table and no Change,so I did it again and No Change???I set my MAF Fail Freq to 0 and my LTFT's are still really bad.Well I shouldnt say no change because my lower rpm LTFT's changed a little not to Neg at Idle now ,But driving down the road I am still seeing -12% LTFT's?You Should see my VE Table ,It looks like the Rocky Mountains,I tried to smooth it out ,maybe thats what I am doing wrong?I dunno.I wish I could put my Histogram on here for you guys to see ,but I dont know how....

it's a 99, you need to copy these values to both primary and secondary?
the easiest way is to work with the primary table, but then to click on the 20,30,40... headers on the left side of the histogram, copy it row by row and paste onto the secondary graph. kinda sucks, but it's not too bad.
another way is to have a spreadsheet that will give you two outputs, so then it's just straight copy'n'paste two different tables.
