Mid 23 ECU update engine braking comparison

Halfway through 2023 a new ECU version was released for the MT09. In canada it became a recall version but for the rest of the world it wasn't always on offer.
I wanted to do a back to back comparison of the 2 versions.
Early 2023 versions are -11 and -21
Mid 2023 versions are -12 and -22
I set my bike back to the stock 21 part that it came with and did some logging of engine braking.
Then I had yamaha update the ECU to the 22 part number under warranty. Yamaha and the dealer were great about it.
The results though do corroborate the general opinion from many that the mid 23 "recall" version does makes the bike smoother and it's all done in the software. It's not something tuners can replicate by editing maps.
