help with fuel question


i've been doing WOT pulls trying to get my fuel to be around 11.5.1afr and it has been a pain doing it. everytime i do a pull my fuel would go to 11.5.1, but when it gets around 3400 rpm to 3900 rpms it jumps to around 12.5.1 then back down to 11.5.1. Can someone tell me why this happens? Also here is a log of this happening.

Look at your DA fuel table. Its all in there, the rest is in slight tweaks of mafcomp. But youve obv got it nearly perfect. Atleast from the spectrum i saw, your wbfactor never gets beyond 4% or so.

sorry bud, saw your new post and see your SD. Im not knowledgeable in that area. I saw a maf reading and didnt look at your ecuconfig. Just the DA tables.
