Wait, is it at 1.0 or 0? I'm a little confused with your post.

I'm trying to get my car tuned . And the dynamic advance is staying at 0 . The logs are showing no knock or timing being pulled . The dynamic advance multiplier is at 1.0 . AFR is threw the roof . I dont think I've got a vacuum/boost leak as ive searched and searched . and i dont lose boost at WOT but I don't think that's what's causing the DA to stay at 0. Driving around normally it runs just fine . Start up is fine , idle is normal , AFR driving around town stays bout 14.7 . I have no idea where to even begin looking . It seems like the car is stuck in closed loop fueling or is there something else .. Timing is spot on , car has new plugs , no CEL's . I'm totally lost ! I just want my car to run right . I'm using an accesport to have it tuned also .

My AFR gets up to 20:1 at wot . The DAM is at 1.0 , the dynamic advance or ignition advice does not move or pass 0. Feedback knock and fine knock learn are at 0
Need Donkey, Zax, Heide, or EJ257 in here to tell for sure...
I just know that AFR is not good. That is INCREDIBLY lean which could melt internals easily.
Need the basics first: What car is it, what mods, etc? Who's the tuner?

06 Sti , CP pistons , VF43 turbo , 07 sti cams , TBE , TGV deletes . Aem intake , cobb accesport , being tuned by infamous tuning .
Stock injectors? Sounds like something is wrong with the fueling. Is your MAF plugged in correctly?
And just wondering, why did you put in 07 STI cams?

Yes injectors are stock , the cams are hollow and have a diff lift I think it was , since u mentioned fuel , my car does run like crap when I'm low on fuel . My injector duty cycle was at about 40% during my WOT log . Possibly pump going out ? Or do I need to dig deeper as in injectors ?
No. If you are only seeing 40% duty cycle then the ECU is not adding fuel. Looking at the airflow G/S and the MAF voltage will tell you exactly whats happening. I suspect either a faulty MAF,a preturbo/post MAF air leak or the injector/MAF scaling is wrong. Post the datalog.
Ok I'll swap out MAF with a buddy , search for a leak again , I don't think it was the scaling as I was getting the same issue with cobbs ots maps
Also...check fuel filter. A lot of 06 and 07s are at the point now where if the fuel filter had never been changed out, it could be severely clogged.
