Is it worth the $300 for the performance tune? I just want it to run smoothly at 4-5k without the slight surging. I really don't want to get into adjusting maps and timing tables like I did with the xb. It really started to become an obsession.  Anyone go from the 12z to 141? Mine surges going 50-55 turning about 4k rpms and it's just noticeable enough to bother me. | ||

I have the 12Z and don't get any of that. Seems to me I'd get it flashed. | ||

It's not an answer to your question, but my bike (09R) has the 131 version, slightly older than the 141 ... Or so I'm told. I rode it nearly 70 miles yesterday, the bulk of it in the 50-65 mph and 4-5K rpm range ... Not a surge or hiccup to speak of. I'll be awaiting the answer to your question too, even though we're coming from different starting points (12Z vs 131). Mike (Message edited by milleniumx1 on October 29, 2009) | ||

I'm not positive I have the 12z, i'm just going by the firmware read using ecmspy, which is BUEZD0P0. I have an 09 CR. The surging is very slight. (Message edited by moosestang on October 29, 2009) | ||

The performance flash tune does not require cell by cell adjustment, only F/R AFV value adjustment. The $69 program requires programming input. | ||

btw, one of the other ways the surging is eliminated is by operating the motor in it's "happy" zone around 6k. As I posted earlier, a LOT of "problems" with this bike disappear when its ridden hard. So, downshift. Avoid the surge. Avoid the 'noid. Enjoy much better acceleration and throttle response. Kinda magic, really. | ||
| Moosestang |
Well riding around at 6k all the time is not practical. The bike is all ready loud at idle and i'm riding at 5am on some days. When I ride to work in the morning, I take it easy, on the way home I do not. | ||
| Cafefun |
It's true the harder you ride theses things the better they like it. I hate my 141 flash would rather have the old one back that caused surging as now I have lost midrange power. | ||
| Jdugger |
> Well riding around at 6k all the time is not practical. Yes, it is. I understand that for the first half to two miles in your neighborhood, you need to keep revs and noise down. But once you hit a major street, or you are getting on the expressway, there's really no reason to go riding around lugging the motor. The little bit of additional noise (if there even is any) 6k makes over 3-4k is irrelevant above 20MPH. The bike cruises VERY smoothly and VERY well with the motor running 5500 - 7k. Around 6k, it really is magic. Smoooooooth. | ||
| Moosestang |
I'm not disagreeing with you jdugger, but should we really have to cruise at more than half the engines rpm range? It's not like i'm trying to get a smooth running engine at 2,000 or even 3,000 rpms. I guess i'm going to buy the tuning software. I had my xb9 running like a swiss watch down to idle speed. My xb9 surged as well at cruise. | ||
| Xl1200r |
Cruising at 6k makes no sense. I mean, it does because it fixes some issues, but I don't see it as a fix, just a band aid. Mine cruises fine as low as 3,000 rpm, though I try to keep it around 3,500. | ||
| Milleniumx1 |
Since I'm in break-in, I got mine to 6K (and maybe a blip or two past) ... But I can't imagine wanting to cruise there. The 4-5K range seemed perfect for my first ride yesterday. It just purred right along! Mike | ||
| Jdugger |
> should we really have to cruise at more than half the engines rpm range It's not a question of "really have to", it's a question of "operating the motor at the base of the power band". 5-6k is "where the fun begins" on the 1125r. Cruising at the base of that is just smart operation. | ||

News from Ohio: The new M3PUS141 has diiferent data locations for some of the parameters compared to the two or three calibrations that proceeded it. Some additional data has also been added. Whenever the data and/or data locations are changed in a new calibration, the O S B software needs to be adjusted and a new version to match created. It takes more time to adjust and then test the new calibrations that have data location changes, as is the case with M3PUS141. There are Ohio Tuner software versions available now for the new M3PUS141 for XB12 and 1125 models. The firmware version is BUE1D130 06-05-09 Ohio is currently working on new M3PUS141 versions of the 2009 Performance Flash Utilities; code has been revised and all that is left is to validate & test; should be available within the next two to three weeks. I'm also nearing completion is a new O S B ECM I/O Utility. Designed for the newer generation ECMs, it will handle the Input/Output of data between the computer and the ECM with a simple, easy to use interface; and is designed for use with the Ohio Tuner software. | ||

At the risk of beating this flash question to death ... I'm still confused about the O S B angle. Tuning an LSx GM product isn't confusing since I've done it plenty of times, but I'm missing something (perhaps something obvious) on the Buell. So the question >> My 09R currently has M3HUS131 versus the newer M3PUS141. So if I wanted the O S B , they could do it on my current 131 version, but not yet the 141? Although pleased with the 131 the first time I rode, if I do upgrade I'd only like to do it once. Right the first time works for me! Mike (Message edited by milleniumx1 on October 30, 2009) | ||

Mike, I am trying to get the details now as i am in the same boat. | ||
| Milleniumx1 |
Thank you! I don't expect you (or any of the other veterans) to do all the work for me. That said, I'm never too proud to admit when I don't know something. I appreciate it! Mike | ||

I can't believe what I keep reading. "The 1125 doesn't like it below 6000 rpm..." "always ride between 5-8k rpm, it's smoother" "If you want to cruise at 2k rpm, get a Harley.." Bullshit. My 1125R runs like a raped ape from idle to redline, NO excuses. If YOURS doesn't, it's BROKEN, fix it. | ||
| Jdugger |
Mine runs just like a bike should when lugged around at 3k, and just like it should when kept in the powerband at 6k. Come to the track and I'll show you yours is the same, too. Are you *riding*, or nursing? | ||

Thank you! I don't expect you (or any of the other veterans) to do all the work for me. That said, I'm never too proud to admit when I don't know something. I appreciate it! Well, no problem. I have an interest in figuring this out as my 09 R has the 131 flash in it as well. My selling dealer ran the "latest" flash according to their Digital Tech on 10/27 and it was 131. Now most guys are saying 141 is the latest flash, including Ohio. I am lost as to why I got the 131....and really it's not a ridability (issue I have not even received the bike) but compatibility with Ohio's software.} | ||

Fresno - Your dealer needs to update his Buell Tech machine. The software does not automatically do so; the mechanic needs to manually. My mechanic had to do the same thing with his machine. As far as the ••• flashes they are designed around a specific Buell flash revision and will not work with another. Buell is moving the fuel and timing tables so an older version of ••• will not "fit" correctly. So...you need to get the most recent Buell flash to baseline the ECU, THEN add the ••• flash. I've got the 141 on my bike and I can now ride in stop and go traffic. Well worth it. | ||

What makes a good track bike does not necessarily make a good street bike. I'm poor and my Loretta is transportation, not a track toy. I can't afford to chew up a set of tires in 1500 miles either. I'm sure my riding style is a lot more conservative than some of you, but I'm certainly not nursing mine. Enough willy-waggin, this motor runs like an I-4 with torque when it's happy, like a popcorn machine when it's grumpy. Keep her happy, ride lots. Zack | ||

Trying to take 90 degree turns in first is a herky, jerky nightmare right now. I guess Jdugger would suggest turning faster, but there's to much of a chance to low side around here(dirt on the roads). I should be able to take a sharp turn in first without the clutch when I'm taching over 3k, shouldn't I? I'm going to call Gainesville hd and see if they can flash my bike with the latest and greatest. | ||

My mechanic had to do the same thing with his machine Unfortunately, my "dealer" has already put the bike onto a truck from Texas to California. I can't wait until I show up at my local dealer and as him to put a 49 state flash on my track bike. It SHOULDN'T be a big deal, but I am confident it will be. Oh well, before I get all wigged out, I'll wait for the hex dump from the new bike. SInce the 131 is post-12Z, I am hoping that it will be compatible with whatever Ohio has done with 141. A hex-dump of 131 will be proof in the pudding. | ||

> I should be able to take a sharp turn in first without the clutch when I'm taching over 3k, shouldn't I? One thought: I have a buddy that does a lot of that "precision drill" kind of stuff. Imagine a marching band on motorcycles. Real tight drill kind of stuff, all 10-20 MPH. The technique they use is constant throttle, and modulating the power using the rear brake. This allows the throttle to be up in the more stable "would normally be accelerating" range, while keeping bike speed relatively slow. So, try it. Keep the throttle steady, and modulate your speed by applying rear brake. Probably, other than holding yourself on a hill, the *only* useful thing a rear brake on a sportbike could do at our skill levels. | ||

Got a question here. I was told that the 141 flash was specific to the CR only. Is that true or false? | ||

"My 1125R runs like a raped ape from idle to redline, NO excuses. If YOURS doesn't, it's BROKEN, fix it." Zac is right. I have had mine "broken" and "fixed", same bike, different Buell tech. I suspect that throttle cables and tps were the cause of my low speed jerkiness.} | ||

Can the flash version be checked with ECM Spy? Or is something else needed? | ||
| Zac4mac |
You can but you get a different number than the DT-II gives. For example, I have M3HUS05Z in Loretta but ECM Spy says it is BUEZD0P0 | ||
| Zac4mac |
A few times, when Loretta was young, the ECM "learned" the right values. That was my first taste of the "IL-4 with torque" feeling. Unfortunately, most of her early life was spent running like a popcorn machine. Very jerky, much like most of you say yours run. I couldn't cruise smoothly below 4500-5000 rpm. Then I got some software that let me set things manually and it's been Nirvana ever since. She is as strong as my XB was in the low-end and scary above 5k. I WON'T go back to a popcorn machine.
