This is my review of Ivans Concours
14 ecu flash.
Kawasaki Concours 14
I am not a techie. Although graphs, tables, and charts are available on
Ivans web site to support my experience,
I wont be referencing them because I dont completely understand
them and it would be disingenuous for me to use them as evidence for my
Also, although Ive been riding for decades and Im used to big
bikes after years on a Yamaha XS1100, I put 150k on a Honda ST1100
before moving on and
rode around Europe on a BMW R1200 RT this is my first Kawi.
That having been said, theres a huge positive difference between the
behavior of the ecu on my 2016 C14 before and after the flash.
The first thing I noticed was the throttle response, which went from lagging
and slow to immediate and zippy.
It made the bike feel more nimble. I was surprised that the flash could
and would affect handling. Acceleration went from labored to light speed.
It feels like a different motorcycle.
Subjectively, riding it post-flash is a lot more fun. Hows that for
a technical analysis? I mean, whats the metric for fun?
Low-speed handling improved dramatically. No more surging, herky jerky throttle
in slow traffic a definite plus on my frequent trips into Manhattan.
Lower gears smoothed out considerably. Way less stress on me in stop-and-go
situations. Deceleration also smoothed out by a lot.
No more engine grab when I let go of the throttle. Shifting is easier and
smoother, especially from 1st gear into 2nd, and downshifting is smoother
Maintaining speed and accelerating in top gear feels effortless like its
not working hard anymore. Vibration is substantially reduced too, almost
like an electric motor.
The bike runs cooler. By a lot. No more bake the rider. Grateful
Gas mileage improved considerably.
And it seems that theres more hp at any given speed so the engine
revs lower to achieve the same speed as before the flash, hence better mileage.
Since this bike sucks up premium gas like its going out of style,
I appreciate that.
The engine catches more quickly on cold starts. It was pretty quick before
the flash, but its another thing that I have noticed.
All things considered, the ecu flash was definitely worth the bucks. And
it only took about ten minutes. And I got a hat and t-shirt, so swag to
boot. Not bad.
I had just been to bike week in Daytona
on my c14 and had a great trip (900 miles each way).

I have been tweaking this bike for 2 years with seat , handle bars , slip-on
, highway pegs, etc.
After reading about the ECU flashes that would improve shifting and the
fuel cut causing it, I wanted to try it.
After looking at all the people doing the flashes I picked Ivan due to his
experience and equipment.
Yes I called and talked with him and sealed the deal. Its worked just as
he told me , the bike is better all the way around.
If I ever need an ECU flash and Ivan has one, that's where its going. Thank
You Ivan , your the real deal.

Ivan was excellent to work with. Very professional and knowledgeable. The
ECU for my C14 has turned it into a different machine (for the better).
It shifts smoother, the jerky throttle is gone, and the bike is just overall
better. Thanks for the awesome work Ivan!

I just had my 2015 Concours 14
flashed by Ivan's. I went out for a quick test ride and ended up being
gone for several hours.
The bike runs cooler, smoother, with a whole new authority. It makes power
everywhere and the midrange, in particular, is just incredible.
My very first impressions were driveability like a spotlessly tuned carbureted
There is cohesiveness between the throttle, motor, and chassis. There
is authority and tightness in the exhaust note, but it is not louder.
Engine braking is reduced and the transition from zero throttle to barely
on is very much like carbureted. This character remains in all the gears.
The stock bike was not bad, but this is a whole other level.
This is my second ECU flash from Ivan. My Vulcan 1700 Classic after the
flash runs (much) cooler, smoother, with an ease to it that is just "right".
(I went through just about everything to get that bike to run well before
I discovered Ivan's ECU flash.)
Like others have said, Ivan is knowledgeable, available, and clearly cares
about what he is doing.
I've ridden and raced and worked on my own motorcycles for 30 years and
I don't know of any tuning trick or part or service that comes close
to the results Ivan's delivers for the money.

First off let me start by saying
how informative Ivan is & always so helpful in answering all of my
I've had Ivan flash my ECU on my 2014 Kawasaki ZX-14R. Drivability &
power are awesome!! What a difference!!
Just recently had Ivan flash my ECU on my 2008 Kawasaki Concours 14. The
best flash I've had by far!!
I've had pretty much everybody's flash & wasn't happy until Ivan came
out with his flash. Would never go any where else again.
Ivan's customer service is outstanding, he called 2 days after I received
my ECU to see how my bike ran & how I liked it. AWESOME. Thank you

I got the ECU flash on my bone
stock 2017 Kawasaki Concours 14. I called beforehand and Ivan answered
all my questions, and described a little bit about
what I can expect with the bike after the flash. Turnaround time was about
an hour after he received it from fedex.
I finally got a chance to ride it after the weather cleared up and went
out and put about 150 miles on it.
The flash performs beyond my expectations, more power everywhere, but
especially in the low-mid range, pulls harder coming out of the same corners,
in the same gear as it did before, but the biggest surprise to me was
the smoothness, very slight throttle
changes, produce instant results, no hesitation anywhere, not a hiccup
one, and a lot less decel during gear changes.

The Concours 14 reflash as
well as the ninja/z 1000 second to none. Fast service, and perfection
I promised an update once I spent
some time on my Ivans reflashed concours 14. This got a bit long, but the
update wont mean much without the background story.

I kept my 2008 concours 14 only because it was a good bike to carry a passenger
with. Yes, I tried the power commander with the butterflies removed,
and the triple secret map... Maybe it helped the bike achieve a 6.5/10.
Although it did help the low end, the on/off throttle response was still
abrupt, jerky and inconsistent.
The bike was pretty good on long rides. Sadly, getting to a freeway meant
the bike had to be ridden across town.
At slow, in town speeds, the low speed handling was awful. Weight matched
up with a strange throttle was a terrible combination.
In the end, the bike spent a lot of time in the garage. After all, I had
a "good" bike to ride...my Ivans flashed Ninja 1000.
Ive had the Concours 14 flash for about six weeks, and 800 miles. I look
for excuses to ride it, and the Ninja got the winter cover, not my 14.
After all, the 14 has heated grips....that awkward, low speed feel is 100%
improved now that the throttle does not fight me.
And for anyone
else, dont get confused by other available flashes.. I waited for Ivans
flash because he fixes the fuel cut.
If you dont mind a jerky on/off response, then choose any flash you want.
However, if you want this issue addressed, Ivan is the only one who can
