Got my update done on 6/4/12. The shifts are much less harsh (that didn't bother me since I like a firm shift), but are much more precise (no slipping feeling, it just goes into gear quickly). I am happy to see these nice, precise, butter smooth shifts. The shifting RPM seems to be spot on, and the car does not hunt for the proper gear on a hill. The ECU seems to predict the proper gear needed much better than before. I believe my idle RPM is slightly higher, which is a good thing since it was way too low and thus bumpy. Much better now.
All in all I am happy with this update, but I really had no complaints before after the ECU adapted to my driving. This new update is adapting well BTW.
