I installed the newly flashed ECU from Ivan.
Never took the plastic off, just the battery cover.
Everything worked on the first try of the button (first firing up of the new year).
I still like the SPORT mode best, vs the Ivan (linear ) mode or the touring mode. He made the idle up a little (1150) , and in SPORT mode it's smoother, and shifting is smoother too. Only thing I noticed was maybe less engine braking on decel.... (?)
Overall great! Fast service and removed the 80 mph limit on the CC too!
