Default Quick Help with LTFT tuning

I have disabled my MAF and reset my fuel trims. I went out and logged my LTFT's for 120 miles or so. I took those numbers and adjusted my VE table accordingly. Now...I know I need to get a log of my MAF Hz and Air Flow to adjust my MAF table for when I re-enable my MAF. When I load my new tune with the adjusted VE table do I need to reset my fuel trims again and get another 100 mile log and log my MAF Hz and air flow or can I just load the new tune in and get a good 30 - 50 mile log without resetting the fuel trims? And after I change the MAF table do I need to reset the fuel trims again?

Thanks in advance

I would leave it like it is and gather the required Hz and Air Flow. Plot those numbers in your MAF table, enable the MAF, reset your trims and do another log to see where you are at.

P.S. I go to bed at 9.

I will try it today.

P.S. I don't care what time you go to bed. I needed assistance.

Also remember, that if you haven't got your timing where you want it and start altering it after you get your LTFT's in order, they will change again.

I reset mine a drove around for about 30 min, just to let the changes soak in that way I would get an as accurate as possible SD airmass calc.
