Looking at AFR numbers

Looks like mine if I were to do a second gear only pull.

Desired Lambda at WOT for a 2010

Interesting, I could post my log, but under WOT, stock, my desired lambda is .68 in second gear along with most of third. This is significantly richer than the table you posted.

Okay here is the log from the sct x4. Run is a second gear pull 2k rpms to 6500, wot. The gold line is rpms the red is afr bank 2 the green is afr bank 1. The car is on the oem tune with 93 octane. Outside air temperature was about 55 degrees.

I would be more worried if AFR1 deviated significantly from AFR2, in general terms.  Your data shows very minor blips, nothing to be concerned about.

There are modifiers also

But OP the screenshot looks normal...enrichment doesnt happen until really late and then goes really rich

To the OP, if both banks agree on AFR,  and we can say that you AFRs look normal, then I wouldn't be worried about a tune.

If you log LAMBSE you will see what the target afr should be...then just check that against measured lambda.

Now its time for boost and a tune sir

Then you can officially join the AJP Turbo "Nut-Huggers" convention, as @Colorado-SHOBro so eloquently dubbed it!

Careful....im not sure if you are allowed to say nut hugger on this fine forum...might be too strong of language....im afraid to say the word damn or hell without fear of retribution ...moderators will pounce

Not a bad practice though in case 3 year olds learn to read

I think you give 3 year olds too little credit.
