Glad to hear the tune/flash is now available for the 2018 versys 650 models. I'll probably spring for the tune over the winter when I'm not riding.
I posted a few weeks ago about how the bike finally feels smooth and broken in after 2000 miles. Yes it's a great improvement, but for a $250 tune, it would be nice to have more of the lower rpms available.
Just to note that the ECU update doesn't just make the lower rpms usable, but actually more desirable. The throttle response after the update is so smooth it's almost shocking the difference it makes. No sudden engine braking when you back off the throttle is another huge benefit. It just makes the bike more comfortable, and I believe more capable, to ride.
The bike feels like its had a complete personality change for the better.
