I am getting 11-021 TSB for engine pinging issue

I bought my car to different dealership to give another try to see they can fix my engine pinging issue. I was told there is piece of software available for update. They went ahead to update it. I put around 100 miles after update. It seems the pinging sound is 99% gone. I somehow heard only one noticeable sound with radio off. At least it is great improvement before update. I also feel shifting is quicker than before. Just like I drove 2010 loaner before, because I always felt 2010 drive lots better than 09 models. Here is info of TSB, even thought I don’t know is this TSB has any relate to engine pinging.
