Sorry if they has been discussed already....I cannot find anything. I looked at Ivan's website yesterday and he has posted a 9/17 Update for Voyager/Vaquero's. Anyone have any intel on this? Ivan reflashed the ECU on my bone stock 2016 in May (love it!) so I got the benefit of the 4/17 Update. I likely will pull my ECU over the winter and send it in. I am just curious if anyone knows anything about what this latest Update does. Thanks!

I have it on my bike... here is my original post after I got it: http://www.vulcanforums.com/forums/54-vulcan-1700/260554-ivans-ecu-flash-upgrade-2.html#post2781026
Not sure how to explain it...bike just runs better, more responsive I guess... feels like more power.
The update is free... just send it in... you won't regret it :)
I have the 4/2017 version, do you know what is the difference with this one? He doesn't post details in the webpage. Maybe we will need to call and ask.

I just had mine reflashed and it did away with the surging at Idle till it warms up, now it idles high till it warms up like it did at stock! I also took it for a ride to change the oil and it seems to be more responsive and smoother threw the power range I love it. I will ride more next spring unless we get a couple warm days as it is 45 degrees here in Iowa now, just a bit chilly for my taste for a good ride :)

Thanks Ivan for a great service in making our Kaw's run better!!!!

Thank you for he update, will probably send mine in this winter as well, the surging idle at startup is a little annoying, otherwise this is the best thing I've done to my bike.

I should be getting mine back from Ivan Monday after having the re-reflash my original flash was done in April 2016. when I talked to Ivan before I sent it in I asked him what the difference will be and he said. "the bike will just be happier, minor changes but noticeable on throttle response and smoothness" will still need premium fuel but knocks will be gone. Will have to see when winter finally turns to riding season

Just giving my 2 cents on the 9/17 Ivan upgrade... Just recently got it back and I am impressed.

A little background, I bought my bike used and it came with the original Ivan flash and otherwise stock pipes/intake and everything else drive train related. I rode it ~25k miles with this original flash. I have never ridden a totally stock Voyager 1700 with stock ECU settings so I am coming from an upgraded bike already.

This new 9/17 reflash is an entirely different world! The biggest difference is the smooth throttle response at slow speeds coming on an off throttle or trying to stay at a steady speed when following traffic in town and it is now as smooth or smoother than anything else I've ridden. This in itself was a big enough change to satisfy me but it also feels just a bit stronger between 2-3000 RPMs than before which is where I typically stay so rolling on to pass at highway speeds is very slightly improved. Also, as was mentioned above, the entire rev range seems smoother and more linear and more refined as if you are less aware of how quickly you are building speed.

Lastly (and this is just my one test so far), I believe MPG's have slightly improved. I did about 310 miles on Sunday which was sunny and temps between 40-55 degrees F. 120 miles highway at 65-75MPH and I got 41MPG with crosswind/headwind. Next 85 miles was slow and tight back roads and "mountain" roads in eastern KY. I got 39MPG likely due to lots of engine braking/climbing hills. Last was the 95 miles of interstate back home where I set the cruise control at 70MPH and sung some tunes. Had a bit of a tail wind and the MPGs were 45! This is all with just me at 180lbs and nothing in the bags. This is all calculated from odometer and the gas pump, not from the bike's trip computer which is generous

I hope anyone who hasn't experienced an ECU flash and especially this upgrade sends their's out to Ivan. Super simple and great results which makes me love riding this thing much more.

I had my ECU flashed by Ivan about 3 or 4 weeks ago. I completely agree with what you are saying. I love how my bike runs now and yes I think mileage is a bit better. Another awesome thing, I hear that cooling fan kicking in more often and the temp gauge has not gotten as high as it used to. With the exchange rate here in Canada, the flash is not cheap but I will say it was definitely money well spent.

Another vote for Ivan's Flash Upgrade!

Just got my ECU back with the upgrade. Single word - WOW! It was like riding a new bike. Smooth through the entire range and more power. I took the Cobra FI2000 off but with the ECU flash, these appear to be hard to give away!

Looking forward to a long ride this weekend!

Safe Rides!

Yeah...I was sure glad I did not wait too long after I bought my 2016 last year to Ivanize. I did it with 2000 miles on the bike. Agree.....WOW. Right out of the driveway, I could feel the power and smoothness that I thought should have been there on a 1700 cc engine. And you should see your temp gauge run cooler as well. Enjoy!
