+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!!!
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
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
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.
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.
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.
Hey Brian! Getting another 09? 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...
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.
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.
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.
Who is gonna tune it for you? 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?
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.
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.
