Positive L-trims going to kill people help
Positive L-trims going to kill people help Ok im getting a positive 6 ltrim at WOT. I have gone through and added 20 to the grids in the VE table that i was getting the possitive ltrim went and test drove it again still getting positive 6 and the ltrims where reset.. I drove about 20 miles and logged some more, same result positive 6. After that i added about 30 more across the grid where i was getting the positive l-trim and went and test ran again. This time at WOT i was getting about positiv .8 but it feels way slower. Am i doing this right? i tried to calculate what my tables should be from the ve thread but i couldn't figure it out
here are some logs and screen shots if anyone would look it over for me

Here is a screen shot of the changes i made the first time around (its in compare mode)

I agree with not messing with the MAF table on a stock maf and only adjusting the IFR table to adjust injector for different size injectors. I am still learning this tuning by computer stuff but thought the PE vs. RPM table was the one to adjust for WOT.?. Supposedly without wideband tuning you will only get it close, the stock O2 sensors aren't real accurate at WOT.
With Edit, I used the PE table, for Power Enrichment, i.e. WOT tuning. VE Table for fine tuning, which +6 Trims to 0- -1 is not fine tuning. Good luck and post up results.

When you said you added numbers to the VE table did you add in the WOT section of the ve table (ie: 95-105kpa areas on the VE table) or the specific areas on the histogram you were seeing positive trims?
How long of a log did you do to see your postive fuel trims?
Did you have the histogram to show Min/Max/ or average values? (when you right click on the histogram after playing back a log)
Did you reset your fuel trims again before logging anymore information? if not it's still going based off of previous runs and will take quite a while to reflect the changes you have made.

Are you making changes to the Primary VE table or Secondary VE table (if you have both)?
I have both Primary and Secondary and since the Histrogram matches the Primary table (15,20,25,30, etc...) I make my changes to it, but then I copy and paste the 20, 30, 40 etc... columns to the Secondary.
I learned the hard way that changes wouldn't show up unless I changed the Secondary table.

As for the primary and secondary VE table i only changed the primary. I have a backup VE table but i didn't make any changes to that because i was under the impression it didn't have an effect unless something was wrong.
