I purchased Ivan’s ECU flash for my 2014 Hayabusa . The only other upgrade on my Hayabusa is a Brocks Alienhead full exhaust.
This is by far the best upgrade I have made . It’s a totally different bike .

The best way to explain the difference is as follows.
The bike is more responsive in every gear and every throttle position at any speed.
I didn’t realize how bad the transition was from closed throttle to any open throttle position until I rode my bike with Ivan’s flash.

That difference alone is worth the price of admission. My Hayabusa is a horizontal missile now.
When I started the bike after the flash, I immediately noticed it ran much smoother. On the initial start and idle if was a different bike.

I can’t say enough about Ivan . He’s the best tuner I have had the pleasure to meet.
His shop is spotless and everything is neat and tidy.
That attention to detail makes me want to do business with him in the future. IVAN YOU ROCK!!!

This is about my 08 V2K that Ivan just re -flashed ..
What a huge improvement over the stock setting. JUST WOW !! :)

He has hit all the spots where the stock ECU has it's downfalls.
After a short test run I can tell you it has much better useable power - in all gears / smoothest running motor now I have ever had. even with a PC 3 / no John Deer 2 cylinder chug, chug, chug that was there even at expressway speeds. / NO POPPING /

5th gear roll on - arm pulling out of your sockets pull with no let up - never had that much pull. Expressway running is a joy now.. smooth and even - what the V2K was made for but never had the program to do so.

I had a good friend with an 04 that has a hypercharger /PC 3 / Hard Chrome pipes take mine for a run -- he came back with the biggest gin and said "As soon as I can MY ECU is going out to Ivan.

Ivan you have done 4 for 4 for me 1 1700 Classic and 2 Yamaha's and this one. All have worked so very well.

Absolutely the fastest turn around. Sent on monday Ivan received it wednesday flashed it and sent it back out same day.
I received it on friday.

As per the flash, wow what a difference it made to the Concours 14.
Changing gears is smoother, more power on 1st-4th gear and those annoying decel pops are gone. top notch service and product.

- 2019 Suzuki M109R

Have a 2019 m109 that is now about 2 months old to me.
I have changed the pipe to a 2 into 1 and put on spike style air cleaners. When I first took the bike home I was disappointed in the way the engine ran. Throttle was very glitchy and you nearly had to pull the clutch in to make a turn and then give is some throttle very carefully.

I did some research and found that the engine is actually derated until 4 gear, so I added a TRE.
It made the performance somewhat better, however, I lost the use of the gear indicator.
The bike still didn't accelerate clean and just ran poorly. I did some research and talked with Ivan of Ivan's Performance and he said that he had done ECU flashing on the gen 1 motors and cured the issues.

I live in Raleigh NC so it took a bit, but I got the opportunity to go to his shop today. He flashed the ecu and what a difference.
From the factory the bike has fuel cut (it completely shuts the fuel off when you close the throttle), this makes for extremely jerky and unnerving corners and riding in traffic.

With the flash this has been cured and now you can actually slow down to make a turn in 2nd gear and then roll it back on while exiting the turn.
The TRE is no longer needed and the bike accelerates hard in any gear. I also now have the use of the gear indicator.

The bike also accelerates hard now due to being programmed so that I am in control of what is happening. The factory top speed limiter is also removed so the bike will pull to max rpm. Speaking of rpm the top rpm was moved up to 7500. The bike pulls stout now.

I had to run up the mountain to Asheville and the road is at some points a 7% grade. I can run along at 70 and snap the throttle and no longer is it lazy, it just rips. Riding on the highway is a pleasure.

My point is if you have a m109 and especially guys that have the gen 2 that no one was really flashing, talk to Ivan. He will make your bike a blast to ride.

Just installed the Akrapovic Header and Ivan ECU flash on my z900rs cafe.
No more Jerky Throttle and even traction mode 1 you can't keep the front wheel on the ground.
I already love the bike but this was the icing on the cake.

May 28 at 10:31 AM · - 2016 Yamaha FJR1300ES

I recently sent in my FJR1300es' ECU to Ivan's Performance Products for him to work his magic on my ECU.
My other bike is a 2nd Gen FZ1 that had been flashed by IPP in 2014 and found that my 2016 FJR1300es’ factory tuning
left a lot to be desired…

The turn-around time is worth mentioning…less than 24 hrs!

Right from the start, the throttle response is instantaneous and it pulls right off idle, without any hesitation whatsoever.

The power delivery is smooth and there is noticeably more of it... everywhere!

I normally cruise around 75-80 mph, right where the FJR’s engine had a slight increase of engine vibration...
Vibes have decreased by what seems like 50% in the 3.5-5k range.
Everywhere else in the rev range, you can feel that the engine is running much smoother than before.

Gone are the decel pops!

Ivan recommends mid-grade or better… tried both midgrade and premium unleaded…
no noticeable performance advantage from my butt-dyno… sticking to mid-grade.

Taking off from a dead stop, you right away notice that there is no more throttle lag and the way the power comes on is like
riding a perfectly jetted carburetor setup (for lack of better description).
Above 5500rpm the bike revs with authority, all the way to redline and never seems to run out of breath.
The flashed FJR will never be a ‘Busa killer, but my K1600 riding buddy is likely going to be seeing my taillights from even further than before.

The cruise control can now be engaged at any speed, in any gear… (Perfect for those never ending 30kph/20mph school zones) … other than that works like before.

Touring mode…feels pretty much the same as before… won’t elaborate, as I rarely use it.
I find the touring mode’s attenuated throttle response is sometimes practical, when the roads are slick/wet and also use it in stop and go city traffic.

“3RD MODE” > I haven’t had time to experiment. As we say in French>> “A SUIVRE…”

All in all, if you are looking to make your FJR rides more enjoyable, with moderate top-end gains and better power delivery “everywhere” … I highly recommend it.

The ECU flash from Ivan's Performance did not disappoint!

I re-installed my ECU this weekend and although I didn't get to ride as much as planned I did get a few hundred miles in.
I paid close attention to how the bike performed at all speeds and functions as best as I could before I got the ECU flash and
then did the same after the ECU flash. I did not do any top speed tests or run each gear to redline or anything of that nature,
but I did ride aggressively at times, though I wasn't trying to outrun any MotoGP racers.

Here are my observations...

The bike feels smoother now in all rpm ranges, noticeably smoother. If you think you're happy with the bike as it is from the showroom don't ride one that has Ivan's flash, it will change your opinion.

I can easily stroll through low speed areas (25-35 mph) without the bike feeling like it is searching for the correct fueling.
Before the ECU flash the bike ran almost like it had bad gas when trying to maintain a steady low speed (2nd or 3rd gear in school zones, downtown areas, etc). You may not notice this much with the stock exhaust, but with a aftermarket pipe you will hear and feel this much more.

The throttle cut is no longer an issue. I tried like hell to feel a throttle jerk and I failed miserably (yeah!)

Normally my hands get numb after about 30-45 minutes, I rode 1.5 hours straight with no issues.

Cruise control now works in every gear which is nice when cruising through state parks and other long stretches of low speed areas. (oem settings for cruise only work in 4th, 5th and 6th gear)

I did not try using cruise control over 100 mph yet, but I'm sure it would work fine. Did someone say Autobahn??

Other than the ECU flash, the only other engine/performance mod I have done is a full exhaust. I rode with the baffle/db killer installed, have not ridden with it removed yet (very loud). I will probably try it soon just to see if there's any noticeable differences.

I highly recommend Ivan's ECU flash. I believe he is one of the most experienced and knowledgeable tuners available.
I was willing to pay the extra $ for his services. I have nothing against other tuners, I just have no experience with them and don't know how knowledgeable they are . Ivan has been around a while and he has never steered me wrong. This was not my first time purchasing from Ivan and I doubt it's the last time. I have never met the guy in person but he was very polite and answered all my questions and concerns.

I hope this is helpful, feel free to ask questions and keep the rubber side down,

I have been riding dirt and street since I was a kid, and I know what is good for motorcycle performance and what is a waste.
I don't normally give feedback on products because I am a busy guy, but in this case I wanted riders to know about your awesome ECU flash.

The 2016 Yamaha FJR1300-ES is a great bike with a few flaws from the factory.
I rode in the mountains near Mena Arkansas and the stock bike scared me with a delay in throttle response around a very tight turn in 1st gear,
and I had to use my brakes instead which was a result as the bike ignored my throttle input. I thought I was out of gas but that was not the case, it was the factory ecu setting and the exact items that Ivans performance ECU flash corrected.

I am a huge Yamaha fan, and I was dissapointed in the factory ECU performance, until I did a google search and Ivans performance products website showed up.
I read the details on the site and decided to try the ECU flash, and I am so glad that I chose Ivan because the ECU flash fixed every single issue that I had with the FJR1300. The Flash is worth more than he charges, do yourself a huge favor and send your ECU to Ivan, you will think that Yamaha should have hired Ivan to design the software from the factory. My FJR is much faster and safer now, It was an amazing change to the personality of my 2016 FJR1300.

Thank you Ivan for perfecting the FJR1300 ECU flash.

Please feel free to repost this email anywhere you think will help FJR riders to improve their ride.

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 for.

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.
Sounds crisper.
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 now.

I will add that the service of both companies is great, and again this is my opinion of two products.

Okay guys, where should I start?
I guess by sending Ivan a big thank you for developing such a great and refined flash.
Thanks again Ivan.

Now on to the review: - Concours 14

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 time.
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 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 bike. 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 questions. 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 Ivan.

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 have read so many positive reviews on Ivan's I thought I would risk Taking off the Power Commander V Fuel controller that was installed on the bike when I bought it used (so throwing away that $400.00 investment that the previous owner made and also risk sending my ECU computer all the way across country to Ivan's. The ECU was back in my 2009 Kawasaki Voyager in less that a week from removal and I was back riding the following weekend with a huge grin every time I whacked open the throttle and saw that I had 1/4 tank of gas remaining at 160 miles when the low fuel light usually came on. WOW I am sure glad I did this!

Purchasing a bike with a known throttle issue and only having forum comments and Facebook posts that this little shop in N.Y. can fix it had me a bit concerned at the risk to say the lest. After not being able to disprove his product, and Ivan himself answering the phone and talking to me for what had to be 10 minutes I pulled the trigger and very shortly after sent in the ECU. Tracking let me know they shipped it back the same day it was received, wich today is almost unheard of.
After reinstalling it I had a hard time believing how much of an improvement it made. I've had this bike from the Gulf of Texas to over 14000 feet at the peak of Mt Evans in Colorado with out hiccup for a total of 21500 miles in just over a year now and am so glad I trusted in others.
Can't thank Ivans performance enough for the excellent work and look forward to their new releases.

Sent out my ECU last week. Have ridden over 600 miles already from sea level to over 8000 feet. Bike performance far exceeds anything I thought possible. Performance is incredible. Mileage has increased. I was very skeptical about sending my ECU across the country but wow, IT is worth every penny. Anyone in So Cal with a 1700 Vulcan can contact me and I will meet you so you can see how great this bike runs now. K&N air filter, Cobra exhaust. No power commander, just Ivan's remapping. Incredible.
