Default I Need Some Autotap Help!!!

On my Autotap I have two Long Term Fuel Trim Bank 1's and Two Long Term Fuel Trim Bank2's. If I log both LTFT1's and both LTFT2's all four read different. I also have two of each STFTB1's and two STFTB2's. My question is how do I know which two to log?

Just another question, what all do I need to log [and what #'s do I shoot for]before I attempt to reprogram my computer with LS1Edit?

I'm by far no expert but I can tell you as I understand it and maybe someone else will correct me if I'm wrong.
I think the reason you have 2 ltrims on each bank is because 1 is an average. Which one is the average I'm not sure. I'd say log the 2 that update the most. I can tell you what I log. ltrims bank1-2, throttle position angle, KR, timing, rpm,O2's,maf,map,FTC, and IAT. Hope this helps you get started.
