you are getting tip in knock even in drive mode. Sport/drive use the same timing maps so that will have nothing to do with your issue. If you watch your log, and slow down the playback speed, every time you give it some throttle you go rich and get knock. Commanded lambda is 1.0 and you are getting .77-.80. Short terms kick in and lean it out and knock goes away. You haven't tune wot, your commanded/actual is way off. Remember tuning in lambda 1.0 is 1.0 regardless of the fuel type you are using, that's why you tune in it. You want .85 under pe, which is almost where you are at, but your commanded is asking for .78 from where I "raped" your pe before you had a wideband. Now that you have one you need to fix it so commanded=actual. Adjust the flex fuel spark tables I attached, this will add a total of 4 degrees on 50% ethanol and above, Log for knock. I also attached the math/graph for a eq error. Your actual lambda under pe is ok if you want to try the timing changes first, but you need to fix it. 6300-6900 you need to add about 4%, 7050-7500 about 7%, 7650 and up 8%.
