My bad, I figured it would have been posted on the tech section, looked through the 1st page and saw nothing haha.
Yeah price could be the issue, but if you are only doing the 4th gen you only need the bin files for it, which are 100 bucks.
If you have multiple bikes, or you are a shop and want to be able to edit all ecus you need the 700 bucks for bin files for all Kawis.
I like the idea though, you can get a data logger and do the fuel map on the ECU, so it would be like a flash, with a fuel controller and autotune.
