Your out of injector and AF ratio doesn't line up with wideband.
 
does it really need to be matched up ? does it hurts the tune? i mean i never watch the AF ratio,i just use a wideband . is it bad? and if yes,what i should do to match the af ratio to my wideband readings???
 
Why are you setting maf clamp at 2000 hz? Thats only like 36lbs/min of airflow. You can probably set it to 2500 with better results. But, I also don't see if you have a MAP sensor or not.

i dont have a map sensor

if i don't have a map sensor,so there is no point of changing from 2000hz to 2500 hz right?

so if im understanding right, when i tune the afr ,the ecu doest read from my wideband,it reads from the (afr thats is o ecmlink) right? because when i open the afr sliders,and when i do detach mode,i see,that the numbers are following the (afr that is in the ecmink) not my wideband sensor....... and i yes,then im runin really damn rich...
 
What are you trying to do with your timing?Looks kinda odd. Oh and a 2g maf reads higher then 2000hz you should raise the Maf clamp up...

And your AFR est isn't going to be close at all unless you change the the Graph prephances to what you have set in the fuel Tab (I highlighteted an Example of what to do with an Arrow)

Also you should be trying to get your W/B to be matching up with your target AF ratio in your DA table, an tune from there after you get everything dailed in better...(At least that's what I do)

I don't know if you seen but you hit 104% duty might wanna turn down the wick a bit(Boost) till you can get your tune a bit closer dialed in. If you have it safely leaned out you can get a bit more out of it but in the mean time in a perfect world you don't want to go over 80-85% duty

what do you mean,what im trying to do with a timing? i never touched it yet... i just corrected the ful tab.i never knew i need to do that... :D and how do i supposed to match my wb to the est afr? by adjusting global fuel??
 
If your Global Fuel and Dead-time is dialed in perfect and you have Adjusted you Maf Compensation(If Needed)You should be Close to your target...(You can see how much difference there is in the screen shot)Before anything I'd set your Maf clamp higher Since you can See that your maf Raw is Higher and their's no reason to have it set that low your not overrunning the Maf.

Your timing map has been changed you can see here... .

you saying ,that i need to set my timing to 18 degrees? i was thinking to go like 22-25 degrees and then try to go round 11.1 afr ..... does it sound good?

NO, No, no, I'm saying that those changes have already been Made...that Second pic is a stock map and the third one is YOUR timing map now. Also 22-25 at WOT is a Tad mit much even it you running something besides pump92 There's something called MBT

I wouldn't make any drastic changes to your Target A/r in DA. till you get it to match up what it's set to now...
 
adjusted mafcomp,deadtime,and i got some logs ,that i just did. idle,cruise and wot .
on a second wot pull i added 3 more degrees on top,and afr made from 9.5 to 10.1 (using an estafr tab)
