Thanks for all your work getting us information bro. :bow :bow I hope everyone appreciates the fact that he is spending time and money on all of this and doesn't have to share any of this info with us. :fact

Maybe if it works, you can find a stock bike to dyno back to back without restrictions...

How would the euro ecu work with an american switch and no immobilizer?? If I order an euro ecu do I have to buy the immobilizer and euro ignition and key and harness?

How much was the entire set, ecu, key and immobillizer? Sorry Im being so nosy but I am thinking of doing this as well. Breakdown the price, if it's not too much to ask and where to allocate. Thank you so much!!!!!

You need the complete kit. Just doing the ecu won't work as the ecu is looking for that key before it lets anything happen. You need the matching key, the ignition so it can detect the key, the harness, etc. I have the Euro stuff now on the bike and I like that it has the immobilizer, should really be something that it's offered here also. Its interesting that the US bikes don't come with the immobilizer! My bike is a 2005 R6 here in Canada and our Yami's have been coming with the immobilizer since then! I wonder if that makes the switch to the Euro ECU on the R1 any different?

What about the YEC ecu, do you need the immobilizer also? Can I go euro harness, yec ecu and american ignition?:chair:

Curious to see how things go :thumbup

Replied to your pm BUSTN. I think we might be the only ones that do not have the immobilizer. The only advantage to that is usually race ecus will plug right in. Immobilizers seem to freak out race ecus, talking from experience with Hondas, not sure about the Yamahas. The immobilizer feature is a complete ecu, ignition, keyset thing, plus you need the wiring harness to get it all hooked properly. I've heard of people losing their keys, not having the code provided when purchased new, and having to buy a new ecu and keys. The thing is, if this reflash works, then everyone that wants their bikes derestricted will still be able to keep everything else, just mail the ecu, get it back, plug and play. So, is the immobilizer ecu specific? Now, if I went with the euro ecu and immobilizer and swapped later to a race ecu, it would not work?? I love the immobilizer idea!

That sounds pretty rad actually. I like that idea a whole lot better than buying a whole new ECU for a little top end. specially when I don't do track days but they are in the near future. I'm tryin for next summer. I still need a suit to fit my gigantic body...well I'm tall

Definitely looking forward to results on this....just what I need, more top end.....

Diel: I have the Euro stuff now on the bike Immobilizers seem to freak out race ecus, talking from experience with Hondas, not sure about the Yamahas. If you find some time, couldn't you just plug in the YEC ECU to test if it works with Euro stuff? Thank's for your work Diel!

Hey Diel, if i post you my yzr125 ecu can you put the r1 map into it? I want it to go faster.

Diel, how far are we from being able to reflash the part of the ECU that controls fueling? Sure would be nice NOT to have to buy a piggyback fueling control computer (such as the Power Commander). Haven't they been doing this with the Gixxers for years now? Theoretically, wouldn't it be possible to achieve greater power gains and injector control this way, due to the fact that the ECU has greater computing power than a piggyback fueling computer?

Theoretically, wouldn't it be possible to achieve greater power gains and injector control this way, due to the fact that the ECU has greater computing power than a piggyback fueling computer? This is great in theory but finding shops that can do it will be the problem. When many struggle to map a powercommander without tuning link working your chances of getting proper ignition mapping, injector timing, injector splits, ride-by-wire throttle opening rates etc etc perfected are going to be real slim. You are really into places that can map Motec and Marelli from the ground up at that level and they are few and far between. But having access to it all would be awesome for sure. I've recently put a hondata ecu into my car. Its a sub board that sits inside the main ecu. The range of adjustment for the money blows the likes of powercommander/bazzaz into the weeds. Now if they would only develop this kind of stuff for the bike world ......

Hey Diel, if i post you my yzr125 ecu can you put the r1 map into it? I want it to go faster. YZR125? Shouldn't you get used to that for a bit before adding more poke to it? Good question and good answer about the fuelling re-flashing :thumbup

This ECU is so much more advanced than the Suzuki it's not funny. No sheot... Every five seconds there seems to be another barrier thrown up against you guys with this. Mucho respect for sticking with it when many others would have forked over for a Euro setup long ago. I so, so hope you get results with this Diel. I really, really know very little about the workings of anything electrical but can't 'blank' processors be bought and a complete new ECU made then programmed with only the info needed? It seems like all the info has to be extracted and re-written so is it not possible to start a fresh one? That's probably made people with even half a clue about electrics laugh but I've often wondered how much it would cost in the bare materials to construct something like an ECU from scratch. My programminging skills ended at: 10 print mark hates school 20 goto 10 :lol

ok, i work on this stuff, that's my job, but I'm in the automotive products, basically in my company (in italy) we develope software and hardware and we produce cellular phones, abs car ecu and so on... basically after you got the cable to connect to the ecu, you need to dump the firmware from it, and here you got two chances. first, make a small application that loads the boot loader on the ecu and extract the firmware or get a full copy of yamaha suite and work directly on the firmware of the ecu. if you go for the first route you need to find some good tool used to dump ecu/cell phone/other stuff firmware and adapt it to be able to read and upload the boot loader, BUT you need to know what eeprom is used on the ecu to store this data, without this info you can't do nothing, cause every tool to program/read/write ecu is developed from the same constructor of the memory, so for ST rom there is the ST software tool and so on. The cpu of the ecu is always blank, it's only a processor and works on the data provided by the sensors and then stored in the buffer (ram). I don't know how the memory on the yamaha ecu works, but it could be possible there are more than one, one used to store basic info (BIOS) and could be blanked pulling apart the ecu and removing the pad battery so you are in "ready to be programmed" state ,cause, by doing this and if it got a battery as stated, generally when removed it just load the boot loader and put itself in a ready to send/receive data mode, and it's enough to send data using a serial cable just as the ecu arrives at yamaha, and in the same way you can read data, unpacket, work on and resend...simply to say but not simple to do... cause you have to know something about programming and for sure you need the datasheet of the eeprom.as said, there could be another memory (called high memory) that could be not accessible by using a simply tool, where generally the map is stored ... cause bios generally contains only the stakes and the "how to" for the cpu. where Diel sent the ecu, probably they got the tool to work on the r6 ecu, that could be the same in hardware but different (for sure in data stored) in boot loader and bios and the results could be a smoked ecu! good luck

Interesting post triplex76, made good reading. Cheers for that :thumbup Damn these things are complex...

i recently depotted an 04 R1 ecu and was able too pick up some serial data off a couple dead end pins from the main cpu but it was pretty much garbled and i couldn't figure out the right baud rate and stuff plus there is no data sheet available for the ecu thats in it atleast with the numbers that are on it anyway. i've got some pics of the ecu itself if anyone wants to see them.

i've got some pics of the ecu itself if anyone wants to see them. I'd love to purely out of curiousity to see what's inside one ;) Thanks in advance.

:thumbup Cheers muchly. Wow...

oh, that's a good base to start from, if somebody get a chance to give a look at the internal of an R1 09 ecu please write the part numbers of the integrated circuits (they are like serial written on) and send me the stuff. I could very probably find the right tool to program it.

the reason its so much easier on the gixxer is because suzuki are using simple known communication protocols and automotive diagnostic standards. suzukis got obd (on board diagnostic) plugs in the main harness ,as most of the autoobiles today, unlike yamaha. that way , the zuuk ecu might be programmed via tools available for the automotive market .

hey there mate , do u know a device that can read kwp2000 or k-line protocol? are you asking about something different from the original programmer on kvp site? http://www.kwp2000.info/ if this is case no, i need to know the part number of the ecu chipset you wanna program to help you ... sorry

are you asking about something different from the original programmer on kvp site? http://www.kwp2000.info/ if this is case no, i need to know the part number of the ecu chipset you wanna program to help you ... sorry i want to retrofit 08 r1 gauge to the older models , and the new gauge is using k-line communication between the ecu and the gauge . i dont have the ecu , so i dont know whats the baud rate and what is the initialization for this type of protocol... sorry for thread jack :snorkel

Jesus... You ever thought of approaching NASA for the funding for this Diel?! Thanks for the update, look forward to the rest ;)

That makes very good sense. Even with my limited understanding of motors I'd agree with that 100% Might as well put carbs on it if you want it to fuel badly :sing:

Haha, they approached me!! Seriously, not too bad here. One thing that will be left alone is the below 7000rpm throttle "optimizing". Lots of people think that not having 100% throttle below 7000rpms is a bad thing when it really works. At those low rpms piston speed vs. port velocity design cannot support 100% throttle anyway. This was even tested by our Brazilian friend on a 08 not too long ago so we're not going to mess with that. There's a thread around here with his results. I'll post up when I hear more. As many 09 owners have said before, thanks for biting the bullet for all of us and hopefully you are the type that can derive enjoyment from helping others. Thanks for all your work

FANTASTIC thread! Thanks Diel!

This is fantastic stuff ... Thanks a heap diel11 for what you're tryin' to accomplish :thumbup

Will there be options for those having a reflash? I mean even if its extra money. Lets say i want to change the TPS map. Or how about the ignition advance. Or rev limit. etc etc. That would be awesome. I've followed the gsxr ecu crack and you can download the software and do it yourself now. I know this is more involved but giving end users the options above would sure entice more to spend the money i think. If you can get me the maps i will work on it for you if you like.

Can you upgrade the Watchdog ecu on my r1 if i send it to you? I'd like to go for the Big Dog ecu if at all possible. PM me a price.

My Jack Russell is bigger than a Rotweiler. At least that's what he thinks :) But being serious for a moment, what i meant before was could you enquire with the remapping dudes as to whether the end user could specify more than just opening up the tps from 80% to 100%. Didn't want them to be mapping it themselves as it really is far more complex a setup than a gsxr but the options to get the pro's to make specific changes for an extra charge would be well worth it in my opinion.

Im in when can i get it done, i want it done like yesterday !!! Im also in the process of getting the factory clutch hub modded as on busas and 1k suz, to elimnate that chatter and problems when launching or slipping the clutch. This new r1 seems to be the worst one ive felt in my opinion. That should be available soon if anyones interested since ive heard others complain of this.

Keep up the good work Diel!

Thanks for the info and look forward to the final results!

Tell them i have some flatslides for sale if it all goes to shit.

Update: Yamaha has done some pretty trick stuff on the 09 in regards to the throttle by wire. For what I am told it seems the throttle chip has lots more calculating, interpolating and all around checking being performed than on the previous models. Evidently, as preventing a malfunction there is the No 1 safety concern around electronic throttle control... I am just "a bit" surprised about that "checksum software is expensive" thing. Probably that's the "user friendly" explanation of a more complex problem, because calculating a checksum really is standard and doesn't take much. Havn't had time to "play around" on mine so far unfortunately...

diel11, do you think they will be able to get around this issue pretty easily ???

I can get the stock ecu reprogrammed and the loom modified both the full yec kit spec. But it will change the clock display and you loose d-mode.

So its basically the same as the other place is doing then. I dont need a clock or d mode. I just want the darn thing to give me 100%tps and if the us bike is dropped a few deg of timing id like that back, and the rest of the tunning i can take care of. I know its not a drag bike but thats what part of its use is for me and id like to get it solved asap.

Ah, i see lol. I would like to keep all stock functions because its half street half race bike. I guess i will patiently wait for good news !!!

Its aweful tempting to get the YEC flash. Still, I like having the D-mode even on the track. Gives some good options based on road conditions. Hopefully someone can get the data from a Euro model ECU and we can use that to flash the US models.

Ok guys, I finally received a connector we were waiting for in order to get the reflashing going. So I am shipping my spare ECU and this connector in a few hours to the guys that handle the technical side of things. I am not an expert on this field at all, but I will try to pass the information given to me as accurately as possible. As of right now I the plan is to remove the restrictions (5k,12k) and leave the below 6800 100% one alone, as that one actually helps. There might be other things discovered as they dump the information out, we'll see. One thing, there is a small chance my ECU will get damaged, and if that happens then we're SOL then as the other one I have is the Euro and I can't risk that one also. For comparison, the 09 R6 they did has been running now for a while with no problems and with a bit more power in some places. So we'll see what happens to the 09 R1. Before everyone goes crazy with this, so far I have seen gains on my bike with the restrictions removed because of the motor work. I am seeing good top end but that's not just a de-restriction benefit, it's a cam and compression benefit. So for people that are going to keep the motor stock, this might not be the thing to do. That being said, I never ran a bone stock bike de-restricted. How is your R6 working after having ECU reflashed. Did it get rid of the throttle opening restrictions and can I send mine to have the work done?

post up the maps if ya can i'd like to take a look at them

Any updates ????

xxx Not good. All of deil11's posts disappeared. Wonder if Yamaha threatened with a lawsuit? Or the company he has been working with are getting ready to come out with a consumer available reflash? :dunno Either way thanks for trying to make this happen diell11.

wow wonder what happened. I was really looking forward to this

mjhhhh dam what happen.. anyone know?? ive been waiting for this one 2.

hmmm this sucks, this was my 1 biigie on the mod to do list.

this was also on my to do list. i was trying to keep up with the posts then they were gone. can you shed any light diel11?

wow , strange :confused:

No problems with the EPA or Yamaha, just tired of trying to help people and then having some copy the research and pass it off as their own. Also tired of all the worthless low lives that say they want something, I go and bother my contacts (who have a lot more important things to do than to deal with me to begin with) and then I never hear anything back. Last guy wanting an Euro set and backing out did it for me. Stuff like that makes me look like I don't know what I am doing to my contacts. I'm just glad I have a derestricted bike and that it really works well. Still debating whether to offer the ECU reflash to the public once it's available. Never had this problem with other forums and don't feel like going thru it again.

Damn Diel, really sorry to hear you feel like that but I completely understand. Thanks anyway for your hard work and efforts, they made very interesting reading and of course, good luck with whatever you carry on with 'behind the scenes' :thumbup :beer

Still debating whether to offer the ECU reflash to the public once it's available. Never had this problem with other forums and don't feel like going thru it again. Well that sucks! I have been keeping an eye on this thread just for that reason. You could always ask for cash first then do the leg work, if the person doesn't understand the reasoning behind it then to bad.

Well diel it sounds like you're in a place where you love doing this stuff and after the legwork figure you may as well pass on your efforts for some kind of compensation and that's totally understandable. Unfortunately it may be hard to separate the business end of things from the hobby end of things and in the end get confused as to why you do this in the first place. Maybe it would be better just to deal with people you know but whatever you do don't stop contributing to the forum, this stuff is just too damn interesting.

Or hell, just take a little longer and let them mull it over before you give some people a call, if they have to wait another week, oh well. The services you offer this forum are well worth any wait. I have never had what you are experiencing happen to me, but I could see where it is frustrating. I hope you don't decide to pack it up, and stop helping those of us less connected, and knowledgeable. I was really looking forward to the reflash. But you are in control of that, and its 100% your decision.

Damn man I was really looking forward to this but I completely understand your point of view. Thanks for all the work and info so far man.

Its this very reason i don't answer the phone at the shop hardly ever anymore ...... ring ring ring "hello, i'm phoning for some free advice" .... brrrrrrrrr My advice is keep it totally to yourself until you have a product or service to offer then just set your price as you want it. If they don't want to pay then screw em. It works for me. Don't need charity cases or assholes wasting my life, i ain't getting any younger answering their shit stupid questions and i won't retire any earlier giving free advice. Keep the faith brother.

Damn! Well said!! Mate you know my feelings on this. Many people these days are just not honourable. We are a dying breed!!

Diel, I'm sorry to hear this... I could tell you are the man in my book, and would like to thank you for all your effort that you put on this forum, and others to help other MC guy's... Also I like to thank Tim as well... You guy's Rock... Stan No problems with the EPA or Yamaha, just tired of trying to help people and then having some copy the research and pass it off as their own.

+10000 on all your help full in depth info on this new r1. I as im sure many others would pay up front and hell ill even pay a little extra just to make it worth your wile since you've made it all that much easier in my modding process and what paths to take!!!

thanks for all the info ! you were always the one with an answer to everyones questions... even to some of mine. i see where your coming from!

Diel- Any reconsiderations or updates? Joe

I wish Diel would come back

I wish Diel would come back Agreed. Its unfortunate what happened. I followed him over from 1000rr.net where he was a huge asset to the community, like here, and was the first to spread the news on the quality control issues with the '08 1000rr along with his amazing build threads. A while back he mentioned that he was undecided if he was going to pick up a RSV4 or not. Perhaps he is over on the Aprillia forums now helping those guys out. Whatever the case I'm sure he is squeezing 40+ HP out of a liter bike engine somewhere. :lol

I just got an 09 a couple weeks ago and doesn't anyone have any more info on the reflashes?

:horse:I just got an 09 a couple weeks ago and doesn't anyone have any more info on the reflashes?

:horse: seriously?

seriously? yea, someone pissed diel11 off and ruined it for everybody.

well then, what companies are doing the hacks for the r6 and vmax that I read about?

I wish Diel would come back No chance i'm afraid. He's now sold his R1 and is getting a smart car and a shoe horn

No chance i'm afraid. He's now sold his R1 and is getting a smart car and a shoe horn oh, that's dirty pool! Good on ya! :)

No chance i'm afraid. He's now sold his R1 and is getting a smart car and a shoe horn He really sold his R1? Seems to be a pattern lately. Im happy with mine, so I guess thats all that matters.

yea he had to sell it..his mom jacked up the paint and the finish on all the metal so bad with her buck teeth and the acidic medley of body juices that ran through her coveralls that he questioned the structural integrity of the bike

yea he had to sell it..his mom jacked up the paint and the finish on all the metal so bad with her buck teeth and the acidic medley of body juices that ran through her coveralls that he questioned the structural integrity of the bike Bwahahahaha. He said something about everytime it got hot sat in traffic he could smell burnt pork ...... But yes in all seriousness, he's sold it to some lucky person and is not looking for a new toy, but not a bike!!

I just wanted to thank Diel publicly for his help with this. Whatever mess this turns into in the near future, it wouldn't have happened without his contribution. :bow:saw:

x2 for Diel, big props for all of his help and hard work. I was watching this closely as I almost bought the 09 and was hoping to get the power on the US model back. I did run across this on annother forum: http://www.jetttuning.com/ecunleashed It did say they will reflash the 09-10 R1!!! Good luck guys.

This is going to be a long one but I have emailing back and forth with jetttuning and here are all the benefits and changes that they emailed me. The turnaround time on the service is about 2 days, but may be longer if a Sunday or a Raceday sneaks in the middle. The service eliminates the closed loop service entirely, as most racers remove the factory O2 sensor in favor of their own tuning instruments. Auto-tune devices (including the troublesome PC5) work perfectly after the flash, without the Yamaha ECU trying to nullify their adjustments. While this service is only intended for track use, we saw no reason to disable any of the factory features such as fans and speedometer, as many different types of racing would still require these. All original functions, including D-Mode, continue to be operational, the only change being that the motorcycle now starts in A-mode. An important aspect of running improved lap times has to do with the on-off-on throttle smoothness, which has been greatly improved. We have been very careful to maintain as smooth a throttle-opening as possible, much more so than when Yamaha shipped the bike to our market. We have identified areas where the manufacturer removed timing for reasons other than performance, and corrected those areas.. One glaring example of this is just above and below 5000 RPM, where sound measurements would be taken. The throttle now opens 100% from low in the powerband, all the way to redline. This was the single largest restriction in the newer Yamaha's and very acceptable gains will be noticed. There is a combination of modifications designed to reduce the deceleration "dive" that plagues the new R1, as well as to address the "jumpiness" when transitioning from off to on-throttle. The motorcycle starts better and warms up quicker (does not over-heat, this has been addressed by varying the exact idle by temperature) with a higher, richer idle. It also pulls away from the line better and is more controllable on those few tracks with low-rpm 1st gear switchbacks. The rev limit is raised a few hundred RPM to allow some breathing room with the new found top end. The other modifications are just technical adjustments that we have found to result in a smoother, more powerful machine. The torque/hp gained by this service is dependent on the ability of your tuner, and modifications to your motorcycle. Therefore we do not provide before/after numbers on any bike, however do encourage our customers to post their own results on the forums, good or bad.They're response was very prompt and answered all my questions. I have the auto tuner and have had nothing but problems in the closed loop area. I will definitely be sending my ecu to get reflash then a dyno tune. I already had it tuned with the restrictions and was not impressed to say the least. I hope this helps anyone with questions regarding this ecunleashed.

I've been emailing them as well. Still on the fence about it. since i'm starting with nothing, i'll have almost a grand or so into it. So i'm right there thinking YEC again. If you could post before and after Dyno graphs, that would be cool. If it's the same machine bonus. If not, I'm more interested in the actual graph, not the numbers so much, I want to see nice smooth lines and no drop off at the top.

ditto on the dyno graphs, i too am seriously contemplating doing this - numbers would be interesting, but I just want to see how the curves are around 5k and see if it truly eliminates the sharp drop off in the high end.... thanks!

Sorry for taking so long, first day on the bike since the re-flash was today. ____________________________________________________ I rode my 09 R1 with the Jett Tuning reflash today at the track and I am very happy. My plan was to dyno it first and get some graphs to post, but I haven't been able to get a friends stock ECU to mea yet. Hopefully later this week. I also did not remap it with a PC, just plugged it in and went. The reflash is supposed to respond to mapping much better than stock as well. Some big differences: Much more midrange pull and holds it longer, very nice! Smoother throttle at 5-40% throttle openings. Not perfect but WAY better than stock. Actually pulls to redline! I would say that actual peak HP is not much different, maybe a few more ponies, but it actually holds it instead of falling on its face at 12k.... Roll off was much improved. I didn't expect it to be changed, but there was a noticable difference. A, B, STD modes that actually work..... Will post dyno graphs after I get it done... Ken ...posted in a different thread...

Could you post the website and contact info for jettuning? This is exactly what I am looking to do. I can't tell you how much this would improve the bike overall in my opinion. I should have an extra ECU soon and it will be mailed to them as soon as its in my hands. Owe, what is the cost?

Here's the website for Jett tuning - http://www.jetttuning.com/ecunleashed_ . Pretty sure Jett charges just under $500. I'm thinking about sending mine to the guy from eBay get the YEC reflash + data cable. I'd rather be able to adjust all the settings rather than just take away the restriction. I want to rock the pit limiter in the neighborhood too.. lol

Hoping to get another pretty soon. Does the ebay reflash change it to YEC specs? Thats not really what I am looking for. I need to research this a bit more...

Hoping to get another pretty soon. Does the ebay reflash change it to YEC specs? Thats not really what I am looking for. I need to research this a bit more... Glad to hear.. Yeah, the eBay reflash changes your ECU to YEC spec, however, you keep your original harness, you don't lose your speedo, or any of the other street stuff you'd normally lose with the YEC ECU. The Jett basically just removes the restriction(s) and changes some other stuff..but it's un-adjustable.

I couldn't find the ebay option last night. Do you have a link? I'm trying to figure out what options are adjustable and if I would really want to adjust them if given the option.

This is a link from my phone.. Hopefully it works. This is for a NEW R6 ECU, the reflash for the 09 is $580 + $99 for the data cable. http://iphone.ebay.com/Pages/ViewItem.aspx?aid=320443600671&emvcc=0

If there are people out there that can reprogram different options into the ecu why cant they just remove the restrciction on the factory ecu that way it functions as normal and no loss of functions. They could reduce there price to a competitive price and they'd make more and we would get what we want. I want my ecu with no restricitons and thats it I can remap myself, Im not concerned with engine braking, I dont need an extra 1000rpm, wire loom changes so on and so forth. The yec mapping would be nice but the loss of functionality, high idle, and other quarks are a turn off for me. Does anyone know how we can just derestrict the ecu, and let us do our own remapping without the YEC quarks? Give me a deresticted stock ecu with all the original functions.

Give me a deresticted stock ecu with all the original functions. That's what Jett Tuning is offering.

How much does jet tuning charge to derestrict it? These tuners are using the YEC software that comes with a race ecu right?

How much does jet tuning charge to derestrict it? Just look back a couple of posts:dundun:

RE: Reflashing Jett is seeming to offer a derestricted ECU that is not really tunable, if you want to add/subract fuel, you need to add a PCV or Bazzaz. The fellow in Florida seems to have "something" I'd be more interested in, more like a YEC ECU in that it seems that you can do everything needed internally, no added cost of a PCV etc.

You? I do everything on my bikes but valve adjustments, EVERYTHING else and I'd rather a trained dyno operator making me a map. It really comes down to what is more common, a tech that can map your bike properly with a PCV or this ECU?

With the JETT, you spend your money, then you STILL need to buy a PCV to compensate for the top end being 100% open as the stock ECU can't compenstate for that. With the YEC type, you have everyting you need and more for less $$ total invenstment. (you don't need a PCV etc) Both systems, you need to tune, no matter what.

For those of you waiting for numbers on a restricted vs de-restricted bike, I just got all of the remaining pieces for my euro wiring harness swap and the bike is now running again. I'll be hitting the same dyno this weekend and will post up numbers on sunday.

My point is that while you can tune this ECU yourself, the JETT one ($80 for the cable to do it), you are going to have to spend an awful lot of time doing so. It costs extra for the cable to program it via your laptop and I'm just going to buy a PCV to piggyback and alter fueling. IMO, it's not worth the hassle when I can get everything destricted via this ECU, then immediately take it to my dyno guy and have it mapped. More money to do it that way sure, but a whole lot less hassle than trying to alter fuel on the ECU playing hit and miss for quite sometime until you get it right.

Actually a lot of the top AMA teams do it the same way you describe. They piggyback a PC onto the kit ECU to avoid the hassle of trying to tune the incredibly frustrating kit ECU's.

Looked back at the jet tuning and ebay guy $5-600 plus a cable! Is alot for a non custom tune. Regaurdless of the option you choose it still isnt tuned to your bike and further tuning will be needed. Id like to see in the $1-200 range tops, for a derestriction. Then tack on your aftermarket fuel managment. Custom race maps in the ecu then the price goes up. Im not taking away from what they do, but lets face it they didnt spend years writing code to develop custom software and spend thousands on trashed ecu's till they got it right. They are charging more than a PC/Bazzazz and those guys created there own product and developed it. These tuners are altering (with premade software) someone elses hardware. And then some require you to alter harness move wires etc.... Im looking for the 100% throttle restriction removed and any top speed limiter removed and any other restrictoins. Not the race stuff just the norm. Give me a blank slate to work off of. For these prices I might as well buy the race ecu and do my own programming. Lets get some good pricing here.

The YEC ECU is cool but you lose so much of the street things. I have been talking with Jett Tuning over the past few days and getting more detailed info from them. The basics are covered here and on their website. On the 09 R1, there are three soft spots (5k, 9k and 12k) and Jett removes ALL the restrictions. Jett also alters the idle, throttle response and engine breaking. These things will improve all around performance and feel on the bike. Yes you should tune with a PC to get the best results but the Jett Tuning offering will have gains also. A YEC ECU is tunable (if you have the skill, time and equipment) but for $550 plus shipping, you can have someone that has already done all the experimentation and R&D. Then tune the PC at a dyno. This will save hours/days of work. When I spoke to Mr. Ethell, he said someone was posting their results soon so we will see what type of results to expect. The peak HP number is not the end-all-be-all in this instance but the all around improvements to the character of the bike IMHO.

....sounds like my next mod!!! Friends at AF1 Racing have a Factory Pro Dyno and said the 09 they tuned was ridiculous. They hated the restrictions, glad to hear bout the fix, thkx.......now I just need a job and it'll be a done deal :(

Not sure what all the fuss is about tuning a yec ecu. Takes me less time and is easier than a powercommander. Very simple interface. In fact the map is much lower resolution than a powercommander.

Now you're just being mean. Imagine if most of the "tuners":dundun: in this country lost their tuning-link and had to actually know where and why to make a change. Chaos!:crash

Hahahaha, then imagine us poor saps that don't 'deserve' the tuning link despite purchasing a PCIII and their datalogging wideband, who have to tune a dual injector bike, by hand, cell by cell, using excel to crunch #'s and intuition to determine how much of the duty cycle the primary injector is supplying!

I'm with Tim. Many comment that they like the "finer" resolution that the PC offers. I like to let the computer interpolate for me. But I think the truth was hit by ffaspector.

I don't get the fuss either. The yec is very similar to a powercommander in the way the mapping works just a lower resolution. I have the reflashed version of the yec ecu. Its great. I'm waiting to get it to my tuner still. He is racing through the 15th. The following weekend I should have it to him. I will post results afterwards.

Thanks for that Dyst, I"m about to pull the trigger on the YEC Reflash. I've seen some Dyno baselines using Stock US, Stock Euro and Base Superstock YEC. There is definitely potential. When I saw the Stock Euro, I just about shat myself, the US bikes are getting shafted by the man!

Not sure what all the fuss is about tuning a yec ecu. Takes me less time and is easier than a powercommander. Very simple interface. In fact the map is much lower resolution than a powercommander. +1 I use YEC ecu's on all of our R6 and R1 race bikes. Not hard to use/tune at all! In fact easier than a PCV imo. Typically we use a Bazzaz Zfi for tuning because it allows MUCH smoother/better fuel mapping due to many more cells (TPS and RPM) than the YEC one. I typically use the YEC to get the 1:1 throttle, use to adjust ignition timing and velocity stack opening, engine braking, etc...but the Bazzaz stuff to map fuel (2 maps, practice:pump, race:vp) and typically the traction control (some guys want..we race in the rain) and the VERY easy and smooth Bazzaz quick shifter. IMO The YEC is the best ecu choice and i dont even get to make a $.01 on it, so not trying to sell ya guys on it. Were currently building 3 2009+ R1s for 2010 and yep, all 3 will have YEC ecu's and bazzaz tuning them.

The new YEC brochure says the 2010 YEC ECU has been modified. Does any one over here know what exactly has been modified compared to the 09 YEC ECU??
