Some quick observations. First you need to charge the Spark Axis above the 1.36 default. In your log, it's at 1.54 at 4600 rpms, so you need to log all the to redline and adjust it accordingly. Then you need add spark values to the newly added cells. Looks like you're adding spark at WOT through the IAT table. You need add spark values into the Flex Fuel Table (B5114) and also add values into Flex Fuel Multiplier table (B5145) so the ECM uses those factors (or %) of the Ethanol Spark values and adds them to the main spark tables for the final number.
