Thanks guys. Personally I think "Rider Comfort Kit" is a misnomer. What the kit really does is provide much needed cooling airflow to the tightly wrapped rear cylinder. I was comfortable before and remain so now. I may even go in and place some tape over the gap between the new rear shock shroud and the seat tray. I've always wondered if having that hot air blow on the ECU didn't somehow muck things up a bit. The new shroud eliminates most of that (but not all). Meanwhile - after all these years - I added a Zero Gravity Sport Touring windshield a week ago. I immediately noticed a nearly 3 MPG increase. In the last 5 years my fuel reserve light would come on around 165 miles (occasionally in the 150's, and on rare occasions around 170). Now it's coming on around 188 miles. Mileage is now running around 49.7 mpg. Plus I find less air pressure on my torso and less turbulent air flow around my helmet. Two thumbs up for the Zero Grav... Reflash? We don't need no stinkin' reflash!  | ||

Whether people want to accept an update or not is entirely up to them, but nobody wants to be responsible for the propagation of false information. The assessment of the new binary being a vanity item is ridiculous. Do you think the engineering department at Buell would make an expensive change like this for no reason? Of course, not, don't be ridiculous! Already posted about the effects of the new binary on cooling temps via datalogs. There's a few other changes made too which I'll summarize here: - Fan strategy optimized - Major fuel PI controller optimizations - Major IAC optimizations - Major spark timing changes, much smoother - VSS changes that don't make sense to me - Fuel/Spark configuration byte changed - Fuel maps modified (very lean, makes bike run like crap unless you revise them) - Startup and accel enrichment optimized - Battery voltage and air temp mods It's a legitimate reflash folks. The firmware has changed which means that they've revised the actual program running on the ECM too. There's new data in there which the older programs don't run, so they've definitely fine tuned things. For one, my idle is rock solid where it never used to be before. The fuel maps are garbage. You'll definitely want to be able to reflash new fueling. | ||

Okay let's see if I understand your points. Buell worked hard on the reflash. The reflash has lots of good things. The reflash has a very bad thing (new fuel maps are garbage per your statement) That last statement conflicts with the first statement IMHO. Other posters have said the reflash does not apply to my '06 anyway. I think I'm still back to why bother? My bike is set up bone stock it simply has a little air scoop to help cool the rear cylinder. If I thought the reflash was for my bike and would improve it in some significant fashion I'd do it. But if the fuel mapping is garbage why bother? | ||

Jim, the fuel maps are sub par regardless of which flash or what year bike you have. You can thank the EPA for that. Only solution is tuning or a race ecm. | ||
| Jim_sb |
Froggy, Thanks. Honestly I am happy with the power my bike produces now (but not the persistent pinging heard when I roll on the throttle at 3500rpm which I have lived with as my Dealer told me it wasn't actually happening). With the Zero Gravity wind screen I'm up to nearly 50 mpg and I don't have any trouble keeping up with my riding buddies on all manner of bikes including FJR 1300, ST1300, etc. at any street speeds under the ton. And AFAIK the Uly has a cornering advantage on all of them which is nice. I am leery that any after-market tuning would reduce economy - I ride with too many guys who have tweaked their bikes and now get significantly worse mileage than stock. Right now I can easily get 200+ miles on a tank of fuel and I'd like to keep it that way. I've read that if I adjust the static timing I can make the pinging disappear I've just never got around to it. I guess I need to give it a go. | ||

What if I told you my open airbox, Micron full system exhaust, American Sport Bike fuel mapped XB12 has gotten me 75mpg peak average, and can easily get 60-65mpg? It is quite nice going 250 miles before the gas light comes on.  A properly tuned bike runs better and gets better fuel economy. You can see several threads in the 1125R section of people gaining fuel economy, power, and smoothness with the bolt on race ecm. | ||
| Jim_sb |
Really? I would be impressed indeed. Let's leave the 1125 guys out of it for now. You're saying I can significantly increase MPG and have a better running bike, eh? Just call Al and send money? Hmmm... What about noise? I like 'em quiet... | ||

Yes, the reflash is for DDFI-3 systems, not DDFI-2, so anything pre-2008 is old school. Everyone inquiring about "the reflash" in this thread is referring to the DDFI-3 reflash available for 2008 - 2009 bikes (2010 is already running BUE2D or even newer binaries). My friend has an '05 XB12S that we recently remapped... we used the latest spark tables from the BUE2D flash and fitted them to the smaller BUEGB table. His bike runs much smoother and gets better economy now from just the timing adjustment. | ||
| Froggy |
I don't know if Al has a map or not for your bike and exhaust. Either way, $250 for a Race ECM, and if you aren't happy, throw it back to stock and sell it. Yes, the Micron is a bit on the loud side, I'm tempted to stuff some dirty old rags in the header. | ||
| Buellerxt |
Mesozoic, thanks for the post. Mesozoic, Froggy, etc., Is the fuel mapping on the re-flash any worse than the stock 08' flash I have? If not, I'm definitely going to re-flash. I may have a look at that race ecm as well, Froggy. I want the mileage for trips! Thanks guys. | ||
| Froggy |
Fuel mapping should be better. They revised the programming several times over the years to resolve issues related to the new DDFI3 bikes. If your bike still has the original flash it left the factory with, you are going to love the newest one | ||
| Jim_sb |
Okay, I checked Al's web site (American Sport Bike) and Buell's web site. No ECM to be found. Where might I find of these magic boxes? If it's $250, plug 'n play, and my bike runs better and fuel economy is the same or better then I'm interested. | ||
| Buellerxt |
Thanks, Froggy. I'm in for the re-flash! I'll email my dealer right now. It sounds like a win, win, win, win! Very cool. | ||

\ {threadjack} Jim_SB, I'm late to this thread, but quite simply amped to see your screen name show up on BWB. Hope you and your family are well. Thank you (again) for your kind hospitality during FBRAT, and should you ever find yourself itching for a cross-country ride on your Uly, me 'n D would treat you like family here on the Parkway. Ride to lean, FB&D \ {end threadjack} | ||

Jim, http://www.EBRacing.com/shop/product32.html When you order, mention that your bike is stock and you want to retain the muffler valve functionality. I know the 08+ bikes auto detect this, but I don't know if the older ones can. | ||
| Mesozoic |
I thought that the BUEYD fueling performed better than the BUE2D, but I never got into full throttle with the BUE2D. I simply drove the bike home and parked it, then reflashed it a few hours later with my revised maps. Maybe it's because I have a Drummer SS can, ceramic coated pipes, and the K&N filter... not sure. In the end, my fueling is considerably richer than stock, but fuel economy is still very good. I would recommend taking the firmware update to BUE2D and then updating the fuel maps, FOR SURE. You'll have a very nice running bike with just the fuel map adjustment as Buell has taken care of everything else like a clean and crisp idle, to smooth low end performance with this one. | ||
| Buellerxt |
Mesozoic, Maybe I don't know what a good running bike really is but I'm very pleased with my stock 08' Uly XT. Froggy is telling me that if I like stock I'll LOVE the fuel mapping on the re-flash which he says is much better, and hey, Froggy is THE MAN! LOL Are you saying that 'after' the re-flash I should ask for something to 'tweak' just my fuel mapping and that as a result the bike will run better AND get better mileage? If so, what is it? Thanks. You've been a great help. | ||

Ferris! Great to hear from you! We just had our annual Yosemite ride. You would have loved it. SB to Ojai, 33 N, Lockwood Valley, Frazier Park, Bakersfield (for breakfast and to meet a friend on an XR1200). Then Woody, Glennville, Fountain Springs, Springville, Lemon Cove, the Mountain House, Badger, Dunlap, Pine Flat Reservoir and on and on. You would have been welcome. Are you still feeding an FJR1300? Jim | ||
| Mesozoic |
Everyone's bike is different so maybe the revised fueling will work better for your bike. My bike however, has been modified a bit so it definitely doesn't run well with the stock maps. It needed some tweaking. Tweaking is simple. You need the cable to connect to your ECM and some very generous people have written some software to help you tune the bike. ECMRead for reading and reflashing the ECM, TunerPro for making adjustments to the binary, EcmSpy.com for the XDF definition files to load within TunerPro, and a copy of EcmSpy for datalogging. Oh, and MegalogViewer which allows you to view and analyze your datalogs and make accurate adjustments to your fuel maps. Yes, it's a bit of a process. That being said, my bike is smooth and hauls ass! | ||
| Jim_sb |
PS. Ferris, I've been spending too much time in the desert doing this....  | ||

All set up to take it in tomorrow for the re-flash! The comfort kit has worked well but I want better cooling and the other benefits Mesozoic and Froggy have talked about. (Message edited by buellerxt on May 05, 2010) | ||
| Buellerxt |
Mesozoic, Thanks, again. You've been a great help. I'll get the re-flash, see how the bike runs, and hopefully be a happy camper. If not, and it seems like a fueling issue, I'll be looking into your suggested tweaking. I hope it doesn't come to that because I'm not close to as comfortable with this stuff as you, Froggy, and some others are. Ths. | ||

Jim, good to hear from you, too. I offed the FJR in early '06 for a new '06 H-D Road King. The FJR was nice, but had several significant-to-me flaws, one of them fatal: MASSIVE radiated engine heat. The RK might seem an odd choice for someone like me, but it's been one of the best motors I've ever owned (43,000 miles and counting), and is seldom at a loss despite my overall agro riding style. Denise and I sold the 'Dome in Cali in late '06 (just before the market tanked) and bought a modest home on the Virginia end of the Blue Ridge Parkway. Our digs aren't yet ready for prime time (still in the process of fixer-upper'ing), but you and your posse are welcome any time. The riding here in the Appalachians is simply sublime. Best regards, FB | ||

Ferris, Sold the Thunderdome! Gadzooks! D made quite a feast for us as I recall before we took off down the Bostrom Highway! Good times! Team Dual Dogs is having another legendary Sequoia Scenic Challenge DS ride up there in June. Incredible trails! Alas I sold my plated DRZ so I could get the CRF250X. Sure wish I had a plate. Mr. X is a hoot to ride in the dirt! Glad to hear you are doing well with D and the RK. Best regards, and you're always welcome here. Jim | ||
| Jim_sb |
Froggy, Thanks, I will look into that tomorrow. I had found his web site earlier but the links were not working. Regards, Jim | ||

My understanding (again) is that there are updated flashes for the 08/10 Uly's besides the Comfort Kit flash. I believe that is what I got to overide my Com Kit flash...I got the latest Uly flash. Have no docs to support that...just a good service writer's confidence. | ||
| Froggy |
Eulysses, you can send me your EEPROM and I can try and verify that. | ||

I got the re-flash today. I noticed on the Repair Order, when I got home, that I got the following re-flash: yo152.1am cal. mu31us282 Does that make any sense to you 'flash' and ecm guru's? It says 'Fan Re-Flash' on the Repair Order. Did I get the latest? The Tech was an arrogant $#%^ and his insecurity, unsuccessfully hidden by his arrogance, compels him to keep info. to himself and avoid answering questions. It's a shame because the owners are good folks. I only rode 70 miles after the re-flash and it was in heavy winds so I can't compare yet. The only sure difference is that the fan did not come on when I stopped. I 'thought' I 'might have' noticed a little vibration from the engine but that could be in my head as I focused on finding differences. Any thoughts on that besides 'see a shrink'? lol I felt no vibration in the bars and the rpm's seemed the same at idle and at speed as they did, respectively, before the re-flash. The bike seemed to perform the same. I'll report back after I put in the miles needed to evaluate any change. I now have the full Comfort Kit, if I got the right flash!

Yep, that's the same part number and calibration ID I got flashed to my '08 XB12Ss in Canada. | ||
| Buellerxt |
Is this the BUE2D, Mesozoic? The one you call the 'new binary' above? That's the one that "Without a doubt, keeps the engine temperature down much better than before. Peak temperature seems to be about 5 degrees cooler as well"? I'm sorry if I'm being redundant but I'm looking for some comfort here, or maybe I should say some 'feels goods'! How do you feel the fan not running when the engine is off effects the bike with this new flash installed? Hopefully the fact that the cooling is superior during running makes the running while first off unnecessary. Did you log that period? Thanks, Mesozoic, you helped me make the decision and your input is really appreciated. I hope others chime in as well. |
