Kawasaki Z650 RS (2023)

Hello!
I have just purchased a bike-side flashing kit that should be compatible with my Kawasaki Z650 RS (2023): https://www.sportbiketrackgear.com/flashtune-kawasaki-z650-18-23-ecu-type-4-bike-side-tune-kit/
But now, after registering it here on FTECU, I don't see this bike anywhere!!
I have downloaded a few installation instrctions, but not sure if any of them are correct (only have 1 download license left so I don't want to guess/try any more!!)
Now, is my bike supported, or have I been tricked by www.sportbiketrackgear.com?
On the box it says 1500-FT-FTDL4 FlashTune ECU Type 4 + a list of bikes (among them Z650), and on the harness cable itself is says BSHA4 (and a serial no).
If Z650 2023 (and Z650 RS, which should be the same) is supported, which instructions should I download?
Thanks, in advance!

Ok, so I removed the tank and dug out my ECU - it's part number "21175-1611" which does not seem to be supported.
Guess I'm screwed 😕 Or is there any chance this ECU will be supported in the future?
It also has the type-16 connector (which seems quite tricky to install the harness on)
