What are some ways you guys are cleaning up AFR during WOT .
I ve been going back and forth between Kflf fkkvs and fuel trims are within spec .
I attached a E85 and 93 Log just trying to clean it up.
Make sure your MAF calibration is spot-on. For instance, I had a narrowband audi TT MAF in my car, thinking it was a wideband TT MAF. These MAFs differ ever so slightly, the stock calibrations are pretty close. I tuned for the wideband MAF, and while fueling was "close", it hunted like yours. Once I figured out that I had a different MAF and updated my MAF scaling to match, it was dead nuts.
