I'll throw this out there as a question. What are the manufacturing dates on the ECU's? Are they the same???
Even though they have the same part number they may have been programmed at different times and plants. The ECU's are most likely programmed in batches depending on build requirements from manufacturer. They may have minor modifications in said build date programming that may have changed what is actually programed into the ECU???? IDK.?????

It's a good thought.(keep them coming) The dealer only asks ECU Serial Number when ordering new. If there was differences no matter how small in the exact same part # that info would be required from Kawi when ordering new or issues. VIN number is not required.

Yet, I know there is differences

I work in the electronic industry. There are always little bug fixes that go on behind the scene for electronic products. For example take to computer pc boards. You can buy the same 2 pc boards but they may have a different
"Bios" or terms same main boot/operating system in ROM that you can't change or see. Only thing you may see is a different version of the bios code if you can read that area. Main operation is the same,
and is transparent too the user as you can't modify this area any way, and the manufacture does not have to publish
this info as the likely hood of them have to repair a faulty ECU is slim to none. Change could be just a small timing
issue, voltage mod, display icon change, ect.

Rick, going on vacation in 2 weeks, i'll send you the ECU then for you to check out. My gut tells me it isn't right, idle seems lumpy.

So Ivan couldn't fix the ECU, that is bad news indeed.

As for gearing issues, I've tried following every thread I could find on 14r gearing. I don't think there are any reports of raising the gearing (more load on engine)causing a problem. None of the guys putting LSR gearing on the bike (me included) have had any stuttering problems. I also don't remember anybody having stuttering problems with lower gearing that went big on the change, -1 combined with +2,3,4 etc. The only issues I really remember are stock up front and +1 or 2 on rear. That combo seemed to take just enough of the load of the engine to fool the computer. Am I wrong?? Your guy in TX seems to be the only reported problem with a big gear change.

There is a few threads like this one floating around. Some Do, Some don't. This is not Flash related. If you are one of the lucky ones with no stutter congrats. I'm not so lucky in that area but My ECU is as Tuff as Nails. Trade off maybe lol. Trying to be positive but this is a Major piss off.

Not all get the stutter .. Mine never had it with any gear change and trust me I have tried every gear combo there is ...Why some do it and some don't I have no clue ..I sent a 0714 ECU to a guy that was using a 0838 ECU , Seems it has fixed his problem ( stutter )at least for now ..I have to wonder if it will come back after he drives it a while .. Crazy is it not ?

I have to wonder if it will come back after he drives it a while .. Crazy is it not ?

Crazy is one word. This kind of crap puts me in the nut house. How can it be that two guys with exact same ECU have two different results.

Ok Lee and I both had the same ECU's. Lee's Never Did have the stutter. Mine always did. So in keeping the science alive one must look to the bike. What's different in the two ? If the answer is nothing, logic dictates we are missing something.

Or there is differences in the ECU. Now how could Kawi Mass produce a Bike, mass produce ECU's all of the same year with different traits ? This is what hurts the brain. Yet it is so.

Now the "will it come back" is a good question. If it does Eyes turn back to the bike. wheel sensor part numbers is my next dig.

Rick, in the linked thread that was with a +1 on the rear and Shane's was also a +1. Bobbybusa never said what gearing caused his issue but being stretched we know it was +something. I still say (not trying to argue at all) that there aren't any reports of "-" rear sprocket stutter problems. I do know my 40 tooth is not causing a stutter.

I hope you don't take this question wrong. I'm hoping you know for our talking back and forth I really respect what you try to do and what you share with us. It is refreshing to see someone such as yourself who has a money making service that doesn't try cramming it down everyone's throat. You, Lee and Shane pass on a ton of great information for the rest of us.

So the question. Why are the flashes using the woolich software having the issue of corrupting an ECU when I don't recall ever hearing of someone with a Brocks/Guhl or Ivan flash having a problem. Does anybody personally (not heard from a friend of a friend) of anyone getting back a screwed up ECU for Don or Ivan?

Bobbybusa bike did it with every gear he tried , and with two different ECUs.. At least that is what he told me on the phone on our many late night phone calls ..

TWO ECU's...same results.What's different then?What WASN'T changed in those ECU's?And did this bike have a Powercommander installed?As well as a flash?

My bike even with a 41 rear which is only down from the stock 42 had issues. Other 14s here also gone up to 43 and there was issues. If I could explain it I would.

On the circuit boards at work I have sensitivity adjustments. This allows me to adjust the Gain plus or minus up to 20 % In the back of my mind I'm thinking the sensitivity settings are different From Kawi from build dates. Or some versions of the ECU do not even look at that input. Fact is there is no science in the guessing game. Currently the only way I know how to solve this issue is to keep buying them until you get lucky. Which is beyond the scope of reality. 900 bucks a crack equals me out.

I should have bought Lees when he offered it to me. Yet i'm very glad Bob has it. Bobs passion for Drag Racing his bike shines through in every word. Congrats.

toledo i'm probably the easiest going guy you're ever going to talk to. If you have any questions please feel free to ask. I will answer to the best of my ability. And if I'm wrong, please please set me straight. I test and try almost everything I read. Bull Shit floats to the top fast. To many have wasted good money on the pitch. You will never get that from me. It's our hobby, good intel helps us all.

So the question. Why are the flashes using the woolich software having the issue of corrupting an ECU when I don't recall ever hearing of someone with a Brocks/Guhl or Ivan flash having a problem. Does anybody personally (not heard from a friend of a friend) of anyone getting back a screwed up ECU for Don or Ivan?

Perfect Question. But, No matter how I answer it my view will be frowned upon. Better to play it safe on this one.
Ivan reads here sometimes. Maybe he will answer the question if he has ever had any trouble.

Brought my below comment over from 1441 as the current read appears rather Negative.

Please dont take this the wrong way. If you told me tomorrow I could no longer have the ability to make changes inside my ECU I would be devastated. With all I have going on with my own bike I would have blown it up by now. I need this to work. Example, Currently I have a 9lb Methanol Boost Flash running in high mode, 6lbs of Boost Flash in low. This all off the Handle bar. This was not possible before. I love it.

On the circuit boards at work I have sensitivity adjustments.

1. I want my 'time units' to be set to ~ 42.900ms (milliseconds)
2. I may have the chip wired to flip-flop ability and flop to ~ 0.042900s (seconds)
3. I am stuck with a single resistor (R1) and to be in range of 4290, I need a capacitor set to this size is a 'component selection' table; finding how to speed or slow time by using 3 hard parts wired to the chip. Or, 4 hard parts and I change from 'one shot' to a 'steady flow.'

One "mono" Shot of stability: Wheel comes around, it shoots 1 round. I now take 1/2-1/4-1/8th and so on I cut those seconds and I can shoot a shitload of times before the wheel comes around one time.

"A" Steady flow is stable: I can wait as long as 3x360 strokes out of 4, before I set the spark at said degree.

WATT does the software do to cause this cell move to induce the kennel or kernel cough?

I'm the last person to ask... ... I'm still building the hardware parts is parts.

Grn14 You would have to ask bobbybusa , what I do know is one ECU has flashed by Don and one by Cblast ..Dons flash was a test to see if he could remove the stutter .. Dons reflash worked for a few miles and then the stutter came back ..I sent bob a 0714 ECU to replace his 0838 ECU and I guess it fixed the problem ? He has not called me so I guess no news is good news ..

We have an 07 14 that has a stutter at 3500 with and without a flash,I personally don't think the Ecu is the problem.it is only noticeable when ridden easy

Sounds like the ECU [?ninja?] sent me and it dialed in at that certain mph to rpm to any-gear. Did a cell dropout at that X to Y intersect? Never flashed, just narrowed the problem down to the brick and a new ECU cleared that cough-stumble-frequency glitch issue.

ROmans, having a crisis (a good one). Sent you a PM.

"Dons reflash worked for a few miles and then the stutter came back"...interesting.You think maybe the ECU was 'looking' for the 'last good configuration' and maybe reset the parameters in there?I think Hub might call that,the limp mode?Don't know if it could do that...seems if it could,it would do it before a few miles.I mean,the ecu has the capability to start adjusting outputs and such to bring it back into a rideable condition.That's what I understood anyway.To a point that is.I seem to remember this happening when the key was cycled.

my 07 didn't start stuttering til about 24000 km,may be its got tourettes,because it sure makes me swear when it happens

my 07 didn't start stuttering til about 24000 km,

WTF? I thought this was just the Gen2 that had occasional flashing difficulties.

ROmans, having a crisis (a good one). Sent you a PM

LMAO, most definitely appears that way. How can it be in this day and age the simplest of things can't be explained. Not to worry I will keep digging until I get it or listen for my screams.

To get my mind off of it, I got back into wrenching and started pulling my Bikes apart. The search for "More Power Captain" makes me Happy. Also installed a CT Full system I got from Lee Pritchard. This went on Forum members 2015 14R. Pics don't do it justice. Just Wicked.

Plan is for one of these bikes to be 400 hp at the wheel by the End Of the week.

Takes software to make the hardware move... This is why you need a software guy and a hardware guy all rolled up in one... Kernel Cough be damned.

Logic and Math Operations,,,, WTF Hub, what have you got yourself into. Abort, Abort the fetal position. But Hang on while I take my shoes off. The study you are into is too big like that bear. Going to drag you away.

Main operation is the same,
and is transparent too the user as you can't modify this area any way, and the manufacture does not have to publish
this info as the likely hood of them have to repair a faulty ECU is slim to none. Change could be just a small timing
issue, voltage mod, display icon change, ect.

Makes sense. Still leaves us the user with no way to pic our favorite ECU. Trying one at a time until we get lucky is Madness.

Big question is, are we having the stumble no matter the ECU or a certain part numbered ECU... where are we on that?

I have 0712 ECU. Stutter has been there from new, or at least since 1000kms. Only noticed it after I changed the exhaust, so naturally I thought it was exhaust, but after trying various different combinations, restrictions and pipe sizes it made no difference. Tried different maps with no change. So I live with it. Will see after flash if there is any change. It doesn't do anything to performance etc. so it's more sound than anything else.
