"Took a test drive yesterday afternoon to check out my newly reflashed
Well, its wonderful...the best way to describe it is Smooth...
I live close to Pilot Mt, NC,
just a few miles from the Blue Ridge Parkway, and home to some of the best
backroads on the planet.
While my 2014 Concours was comfortable enough for freeway drones, riding
twisty backroads meant endless throttle transition lurching.
And - despite a behemoth motor, the bike often seemed wrong footed and gutless.
Roll off the throttle for a bend - lurch! (correct your line as engine braking
clunks in)...pick up throttle coming out of the apex - nothing... then lurch!
(correct your wobbling line once again).
Sound tiring? Ivan (of Ivan's Performance Products) explained the problem.
Seems that the engine control unit (ECU) on this big Kawaski actually switches
off the fuel injectors during throttle roll off (causing that big decel
Rounding the curve, throttle roll on creates a delay, followed by a poorly
calibrated injector restart (lurch again).
Add to this ignition timing maps more focused on cat converter heating than
driveability, and you have a lovely (but frustrating) bike that generally
just sits in the garage.
The good news? Ivan's reflash fixes all of this.
It transforms the C14 into a smooth, pleasant ride. And, there's more. Much
better roll on torque, vastly improved parking lot behavior. Overall - Smooth!

Ivans C-14 flash is well worth the money!
Ive owned my 2017 Concours since December and overall I've been very
happy with my decision to buy this bike.
However, I was surprised and a little disappointed with the low-end torque
the C14 delivers in its stock form.
The other readily noticeable annoyance was the stock bikes overly
heavy engine braking.
Ivans flash dramatically increased low-end/mid-range torque and all
engine braking related issues were solved.
These are by no means the only improvements made by Ivans flash. These
were just the most important to me.
Overall drivability and power were greatly improved.
The description of the flash on Ivans website is spot-on! If you love
to ride youll love this mod.

Concours14 ECU flash upgrade:
I recently entrusted Ivan to upgrade my 2010 Concours14 ECU.
The Kawasaki factory created a great motorcycle, however as is the case
with many Japanese machines, they can be made better.
As a former software engineer, I understand that the software 'tool' you
use can make all the difference.
I was confident that Ivan's proprietary tuning software would dig deeper
into the stock ECU programming,
and get to places where off-the-shelf software products (XXXXXX, etc) would
The result of Ivan's flash is a much more pleasant machine to ride and operate,
one that feels smoother and more responsive.
The bike is already quick in stock condition but there is definitely a power
boost after installing a Delkevic slip-on using Ivan's flash,
especially in the mid-range (4,000rpm - 8,000rpm).
After a brief ride,
I already know the bike will allow me to enjoy back roads more, without
worrying about fueling issues and the on/off condition of the stock setup.
Ivan's flash upgrade has made my bike much better and is very much worth

The drive ability and power is much improved, pulls hard all the way to
10500 RPMs like it never did before.
My bike is stock other than the ECU. Thanks Ivan very professional and fast

my flashed ecu arrived is the very same moment I began to love my Concours.
Absolutely the best use of money for this bike. Its a must.
Ivan is by far, the best tuner,
and most knowledgeable guy I have met in the industry.

Outstanding improvement! The word SMOOTH comes to mind in every area. Smooth
throttle in the city without jerkiness, and no heavy engine braking.
MUCH smoother gear shifts. Acceleration improvement sneaked up on me a couple
of times until I got used to it.
Also, no more popping on deceleration. Much stronger and immediate roll
on in 4th through 6th.
I have a new bike without the expense.
This is my comparison review
of 2 companies offering ECU upgrades.

I must clarify that it is not a comparison between 2 people, but simply
2 products available to the public.
I own a 2015 model C14 with the full AreaP system.
My initial ECU flash was installed by Shoodaben Engineering prior to the
Instalation of the full exhaust system.
This flash did make a noticeable improvement in low and midrange power,
however the on-off throttle transition was not as improved as I had hoped
After the Instulation of the full AreaP system, I had Shoodaben upgrade
the ECU to the appropriate flash.
The bike certainly felt fast but I was somewhat disappointed with the overall
results and in particular the low and midrange roll on.
I have installed full exhaust systems on other bikes in the past and understand
there can be low end power losses,
but I felt that there was more hidden in that motor.
After some additional research, I decided to try Ivan's Performance products
Flash which the company has developed for this Exhaust system.
The difference in the way the bike runs is simply amazing.
Considerably smoother at all rpms.
On/Off throttle transitions are absolutely immaculate.
Zero Decal pop.
Revs much quicker, throttle response is immediate.
Low and midrange roll on power is extremely strong, much better than just
a slip-on, and the top end power!! Wow.
I feel the bike cannot run any better, smoother or stronger, than it does
I will add that the service of both companies is great, and again this is
my opinion of two products.

Chalk up another win for Ivans Performance.
Just got it in tonight and went for short ride. Only 20 miles. WOW!
You hit the nail on the head with this one Ivan.
I fully expected to be impressed by the extra power, but was not fully prepared
for the PHENOMENAL low speed manners.
Great job Ivan. I hope any bike I purchase in the future, youll have

Bought Ivans flash for my Kawasaki
Concours 14 about a year ago now and have loved every second of it.
Now, two weeks ago I sent in my ECU to update the flash due to the purchase
of a slip on. WOW. I thought the original was good, this blows it out of
Low speed handling, power delivery, sheer power and torque.
Its phenomenal. Im about 320 lbs and the bike will still lift
up the front under hard acceleration in first and into second.
My 08 runs cooler than ever now and smoother. Zero engine vibration. Zero
jerkiness in throttle on/off.
Engine braking is very predictable and pleasant. Case and point, this is
hands down the best bang for you buck on a performance mod for this platform.

Okay guys, where should I start?
I guess by sending Ivan a big thank you for developing such a great and
Thanks again Ivan.
Now on to the review:
The name of the game is SMOOTH. Everything feels smoother. Shifting, throttle
response, vibrations are reduced, speed climbing happens FRIGGIN QUICK!
Be careful with this, or you will be seeing red and blue flashing lights
on your rear view mirrors very quick ;)
The first night i put on the ECU when I got it back from Ivan's shop (mind
you I'm in Canada, and shipping took literally 2 days,
Ivan had the ECU ready the day it arrived into his shop), I went for a 'quick
ride' around my neighborhood; boy was it a quick one!
I was having so much fun with the newfound responsiveness and linear power,
I had trouble keeping my bike under 180 km/hr! (115mph).
Shifting gears is super smooth, which before was notchy and annoying;
Now I actually look fwd to riding 2 up with my GF and not be banging heads
every time I switch gears.
On that note, I like that I don't have to be conscientious constantly about
my riding to be smooth, which is a huge nuisance on the stock bike!
Now I just ride the thing, and it is smooth straight out. I feel like an
a$$, I should've done this as my first upgrade!
Mileage was pretty great, getting consistently 47 mpg at 130 km/hr (80 mph)
over roughly 200 miles.
Vibrations were reduced; the way I noticed this was that before my hand
would go numb from the buzz after 15 km or so,
and now I can hold the throttle for much much longer before that happens!
The engine decel reduction is one of my favorite aspects
of this flash; now when I let go of the throttle I don't feel like I'm gonna
go fliying over the handlebars!
Also, it is easier to be smooth in the twisties. I love how on-off throttle
feels so much better!!!!
When stock and going at supersonic speed and releasing the throttle, the
bike would "shake its tail" quite a bit before quieting down.
Now it does much much less of that, which is a huge improvement to me!
Downshifting is also so much smoother
now, close to perfection I would say.
The engine, and the way it feels, a whole new chapter.
Definitely running cooler (it was a warm weekend here in Ontario and I didn't
feel baked at no point, at all, even on traffic).
The engine literally feels 'happier' and freed, if that makes any sense.
It finally feels like the 1400 cc inline 4 that it is.
It delivers power linearly (and a lot of it). Torque is always there. I
did a roll on on overdrive, from 65 km/hr and was doing 120 km/hr in no
I really love how it pulls with so much authority now. Honestly my friends
could not keep up with me on the twisty roads or on the highway!
If you are hesitating about doing this flash, stop hesitating and just do
it. You will be glad you did, as I am!
To be honest, it feels like I was given a new and improved bike! Smoother,
stronger, faster, and cooler.
Thanks Ivan, you outdid yourself!

I rode 5 hours to visit Ivans shop and demo his flash to compare with
my current Shoodaben flash.
I ended up leaving with Ivans and can say that Im done looking
for a flash for my 2015 Kawasaki Concours 14.
This tune greatly impressed me as I was able to have back to back 5 hour
runs for easy comparison.
This bike just cant get any better. Not bad for a 10 plus hour day
in the saddle.
The biggest thing that immediately impressed me was how smooth the engine
Any buzzing or vibration that was felt through the grips before was just
about gone. I had no issues with buzzing through the bars for the 5 hour
I actually found myself gripping too tight, especially through many triple
yes its that smooth.
The engine just seems happy spooling up to red line letting you know its
a sport bike with greatly improved power delivery.
By improved power delivery I mean it pulls harder and more predictable than
Cruising around town is easy and smooth. No jerkiness like before, and the
power is so smooth between 2k and 5k.
This engine now feels way more refined and dialed in compared to stock and
other tunes I have had.
I wish more people could compare the differences between other tunes and
Ivans like I have.
My exhaust even sounds less raspy as though there is increased efficiency
about it and maybe even quieter if thats possible, most likely because
I am using less throttle.
This bike just got more enjoyable!
I do want to add that Ivan let me demo his C14 with the full Area P exhaust
I was blown away with the power and light throttle. I am not ruling out
the upgrade from my slip on but well see
Great work Ivan!
By the way I had to submit this via my wifes page because mine did
not have any option to leave a review.
If you want that Connie to run
better than you ever dreamed just send that ECU in and thank me later.

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.

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
