We've discussed this a bit here and on advrider and I don't know of anyone who has tried the new 2022 quickshifter on an 18-19 CRF1000 yet. I have an 18 ATAS with the original style qs and I think the 2022 qs will work with the 18-19 CRF1000 no problem.
Here are my thoughts: The 18-19 qs works with 20-21 CRF1100 and vice versa. The 2022 qs works with 20-21 so it should work with the 18-19. The connectors are the same, no wiring differences, etc. The differences are in the initialization of the qs which vary from 18-19 to 20+ due to the difference in dash / tft setup. So you will need the initialization instructions for 18-19, which I've attached and will require Honda SCS connector or jumper for the DLC plug to initialize. The other attachment - CRF1000 Accessory User Guide includes instructions on how to adjust the qs settings. I really don't know why Honda chose not to include those in the qs installation instructions.
If I didn't already have the older qs on my 18 ATAS, I would have already tried the new 2022 qs.
