I too had Ivan flash the ecu on my 2014 I bought this May. I have about 3,000 miles on it and run the Ivan mode all the time. I don't even think about the other two. I get an average of 45 mpg and run midgrade and will continue to do so as it is only a few cent more. I have 2 brothers exhaust and the bike is so much smoother than before. I would definitely do it again/ I have used the cruise at 35 mph when going through known speed traps and I like that feature too
I would do it again without hesitation. I've put just over 1000 miles on since being flashed with no complaints. The power increase is noticeable but it's not a huge increase. His dyno sheets show about a 5% power increase IIRC, I'd bet that's pretty accurate. The driveability is definitely improved... no more on/off throttle hesitations, it just does everything smoothly now. And I LOVE the 3rd drive mode. Touring mode (for me) is annoyingly sluggish and Sport mode as to twitchy for everyday use. Ivan mode is linear... if you want half throttle you open the throttle halfway. Reminds me of a pre-emissions bike, it just runs "right" all the time. And no more cruise control limitations! WooHoo!
You do need to run mid-grade gas but that's about $1.50 per tank difference. Not a big deal in my book.
As bolt-on power adders go I'd give this an A+
Edited to add... I've increase 1-2 mpg on my display and I've not been riding for good mpg numbers [IMG class=inlineimg]https://www.fjrowners.com/forums/images/smilies/icon_wink.gif[/IMG]
Ditto on your comments, my experience also..... except for the mid-grade fuel part that Ivan recommends. With the timing advancement, it would seem mid-grade makes sense, I get it, but I just went on a week trip where two of us ran regular.... several tanks in all kinds of situations, cruising to twisties.... we did not feel any detrimental effects nor did fuel economy change from our pre-flash days.
The engine from cold does rev up near 2000 rpm on cold idle and takes longer to warm up (timing advance makes it run cooler). Takes a couple of times to get used to that, but all good. I believe Ivan set the parameters such that the cooling fans come on at a lower temperature as well, as we noticed and we're OK with that.
I noticed the higher than normal cold idle also but it seems to be better now or maybe I've just gotten used to it. The first tank of fuel I ran after the flash was 87 octane and I didn't notice any spark knock or driveability issues either but I'm going to stick with the 89 cause I'm a chicken s... that way. lol
And I agree the motor runs cooler. And the fan does seem to run more often which I believe is a good thing. The reason manufacturers went to liquid cooling in the first place was to keep the operating temp more stable which allowed tighter tolerances which made more power and more efficiency. But today they seem to be letting engine temps swing more and more. I haven't really been keeping up with technology of late though so I could be all wrong.
I had Ivan flash the ecu on my 2013 2 days after I bought it/got it home! Took it out on a Sunday afternoon, mailed it out first thing Monday morning USPS Priority mail. He received it Wednesday morning, installed the new maps and sent it out that afternoon Fed Ex 2 day (with my ok). I received it back Friday by noon. 2 thumbs up! I also run his map without any thought of switching to either of the other maps. I am running Leo Vince slip ons.
