It is pretty awesome, eh?Yesterday I got out and did a trip up to Whistler and came back the slow way going up Callahan valley and Squamish river road to give my 2015 650 ECU flash a good workout. The best way to describe Steves flash is found in the name of his company, Shoodaben. This is what SHOULD HAVE BEEN from the factory! It has inspired a new level of love of riding this bike for me. The throttle roll on and off is so smooth,no jerkiness. I run a 15T-44T combo stock muffler. The whole spectrum of gears seems balanced now. The range of all the gears is bigger as theres noticeably more power down low so theres way less fiddling looking for the right gear. Hence less shifting. I dont use a gear indicator so Ill have to retrain my instincts. Can stay in any gear longer. Top end is probably the same but I never get there anyways.But its the getting there that is improved. The legendary Kawi midrange is more pronounced now,particularly leading up to 5K. The 2015 649 felt like it was asking for more fuel before under 4k before,now its getting it. Lots of room around 5 K right where I love it. Crack the throttle there and it has more depth. Engine runs smooth like a factory tune on 87 gas,no gurgling or farting. Very seamless. So without going on too much Ill say this is a very professional ECU tune,well thought out and no back yard job. For me,the connection between human and machine is what I love about a bike.And this ECU tune has brought it closer.
And that was at the very end of about 4 months of work previous to that! SteveIt is pretty awesome, eh?
Disclaimer: I spent the better part of two days playing at the Shoodaben Skunkworks being a guinea pig working on different settings to get to the final product. Quite the eye opening experience watching a "tune" evolve and being a part of it. And it was a real pleasure to watch a master at work. I lost track of how many times the ECU came out, got reflashed, test ridden, came out, reflashed, test ridden, came out, reflashed...until it was juuuust right.
Nice work Steve and also to your test pilot Steve! Got out again on the weekend for a ride with a buddy on an Africa twin for a couple hundred K of a mixed pavement loop out to Harrison lake and back. I like twisties with up and down and now Im getting used to my new flash. Smoother throttle response both on and off(more sophisticated for lack of a better description), more power leading up to the mid range and above. Less thinking about getting stuck in shifts,more concentrating on at-tempo mastery of control. Feeling the bike. Shes got a bark now in 3rd and 5th gear seems bigger for non-freeway cruising. Kawi is good at creating power but Shoodaben is good at refining it. Im thinking Ill not crave a bigger displacement bike now, this 649 fits my needs. Two Thumbs up!And that was at the very end of about 4 months of work previous to that! Steve
I put another 340 KM on the bike, 80 to 90 KM/HR cross winds, had my heated gear on after 3PM. The new flash is one of those things that explaining / documenting, can not possibly come close to experiencing it, it is just that much better!I finally got a chance to reinstall my ECU and go for a test ride after getting it back from Steve a couple weeks ago.
This tune is even better than I anticipated. The hesitation / bucking below 4000 RPM is just gone. The bike happily accelerates from 2500 RPM in all gears. And it does so authoritatively from 2500. This is how a 650 twin should feel! :grin2:
The on/off throttle jerkiness is gone too. It's much easier to modulate at small throttle opening cruising speeds. This is how the bike should have felt from the factory. Buttery smooth and refined!
Finally, overall power is definitely improved. The bike doesn't suddenly feel like it's a 1000, but there's a notable improvement in power everywhere. It just feels a tad stronger and I consider that just an added bonus to the really important improvements I already described.
This is the best ~$250 you will spend on your Versys 650. Do it!
P.S. Thank you Steve for this awesome contribution to the Versys 650 community! I absolutely love this bike, and you fixed the one major complaint I had about it.
Can't respond to the gen 2, but I had the MK-1 , let me say it was open loop and never had the issues of the MK-3. Performance could be attained very similar to the MK-3 new flash by adjusting the TPS , you really need the $24 harness and a good 2 decimal place DC meter. Several also did the vacuum hose mod, I tried it and it was just too rich on the MK-1 when engine braking.I wish we could get this on the Gen 2 650s. Everything time a thread on this Flash pops up I get so jealous.
