Chris & I dynoed my bike, reflashed it and then dynoed it again Saturday at Liberty. The charts unfortunately start at 3500 RPM and don't speak to the low RPM performance. Pre and Post peak hp was about the same with the higest (128.7) on the first run which Chris said was because the engine was cooler. The good news is that the bottom end changes didn't hurt the top end, but then realistically why should it? I rode the bike in traffic around Rahway to observe bottom end performance and it seemed much better below 4000 but I wasn't convinced. The real test was on my normal commute to work which I have done many, many times and have observed very closely. I can say with complete conviction that they fixed it. It will now run happily in 3rd at 35 mph and 3000 rpm. No surges, no death rattle - perfect, as it should be. Let it drop to 2500 or even a bit lower in 3rd doing maybe 30 mph and it will rattle slightly but pull right through it. My commute is all back country roads where I'm dodging turkeys, squirrels and deer, not to mention the little kids waiting for the school bus. The point being that I need to putt putt along basically observing the posted speed limits which are mostly 30-35 mph. Before this reflash it was torture constantly shifting between 2nd and 3rd to try to keep the bike happy. Now I can leave it in 3rd and enjoy the ride and concentrate on missing all the critters. One other plus - since I owned the bike it would stall EVERY time I started it cold. This morning it started and did not stall. The instant mileage seems to be up about 8 mpg, but I'll have to observe it more. My average was 29 mpg which I just reset se we'll have to see if that gets better. One cautionary note - The AFV values may not have had enough time to settle in and I hope it doesn't unlearn the current settings. They are now at 100/100 and they were 105/100. It's a bit cooler here now too. This morning though, was 65 which is about what it's been during the summer. Mu bike is all stock except for the solenoid being removed with the Buell plug installed. I forgot to add that I'm at 300' - 700'. (Message edited by jerseyguy on September 22, 2008) | ||

Do you know the reflash #? | ||
| Pyrateryderzmc |
Yes, I too would like to know the reflash code or number, so I can go get it done. | ||

Also a post by Odinbueller from another thread. http://www.badweatherbikers.com/buell/messages/290 431/357538.html?1222092553 2008 1125R CALIBRATION PRODUCT PROGRAM 0505 Purpose Buell Motorcycle Company has recently developed calibration updates for the 2008 1125R models. These updates provide improved cold start, driveability, fuel mileage and reduced heat. In the interest of customer satisfaction, Buell Motorcycle Company has elected to initiate a product program (Product Program 0505) to update the ECM calibration on affected vehicles. Motorcycles Affected This Product Program applies to all 2008 Buell 1125R models built beginning of model year October 29, 2007 to end of model year July 17th, 2008. A VIN list specific to vehicles shipped to your dealership is available via h-dnet.com and is no longer attached to mailed bulletins. This list may be found by following this path: h-dnet.com/Service Toolbox/Product Campaign and Open VIN lists. Select Product Program 0505 campaign to view VIN list. NOTE If the vehicle does not appear on your dealer VIN list, refer to Safety and Product Campaign History by VIN link to verify if vehicle is affected. Customer Notification Buell Motorcycle Company will send a letter to registered owners, in the United States, notifying them of this non-safety related condition and instructing them to contact their dealer for the replacement service. A sample of the customer letter is attached. Customers outside of the United States market may not receive this notification. IMPORTANT NOTE Please be advised that the services delivered under this product program will no longer be rendered at factory expense after two years from the date of this bulletin. Required Dealer Action ECM Calibration NOTE After connecting to the vehicle but before beginning the calibration reflash, connect the AC power adapter to the Tech Link II to ensure correct system communication. 1. On vehicles that are covered under the product program, verify the current calibration using Digital Technician II and reflash the calibration if updated calibration is not present. See Table 1 for calibration numbers. 2. System functions included with new calibration: ● Improved cold start ● Improved driveability ● Improved fuel mileage ● Reduced heat ● Accessory port is controlled by the ECM and will be turned off if the ECM reports a deficit on the charging system. Do not install accessories directly to the battery or anywhere else on the bike except the accessory plug. ● ECM will now control cooling fan operation independently and is regulated by coolant temperature and battery voltage. ● Idle RPM is now impacted by inputs from coolant temperature and battery voltage. This may raise the RPM slightly if the programmed conditions are met. Under normal operation the idle will remain at 1250 RPM. ● It is normal for the fuel pump to cycle periodically to maintain fuel pressure after key off. The amount of time allowed for this has been reduced from 20 minutes to 10 minutes maximum.} | ||

Hey, Steve...just curious what the curves looked like pre and post? Identical? Thanks to you and Chris for filling the request. I feel very comfortable now going through with the latest flash. | ||
| Misterrich |
Im only getting 22mpg after the flash. Could something else be wrong? | ||
| Jerseyguy |
The curves were nearly parallel. He did 7 runs 3 pre and 4 post. Each run was slightly less than the previous. Chris attributed this to the engine & dyno room heating up. I'd like to do another run in the near future with a cooler engine to see if anything has changed. One other thing, the A/F ratio on all runs was nearly flat with 95% in the 14.7 to 14.8 range. This is no doubt for EPA reasons. I wonder if this were more like 13.5 across the board how much more power would be made and how much cooler would it run.

Im only getting 22mpg after the flash. Could something else be wrong? Maybe the flash didn't take....what kind of confirmation is given the Tech with the flash is successful or not? | ||
| Xbswede |
When I had my flash done I was given a print out which shows the before and after calibration ID of the ECM on my bike. I had to have mine done twice because the first time the same Calibration was loaded that I already had. The only way this was discovered was that the print out they gave me had the same ID before and after. | ||
| Fresnobuell |
Just asking cause I have limited confidence that mine will be done right this weekend... | ||
| Misterrich |
Im pretty sure the flash took. My bike runs great under 2k rpms and it didn't before. It also used to stumble and die when starting. It would take 3 tries to keep it running. And before i was getting 34mpg. | ||
| Fresnobuell |
Any chance you messed up the MPG math? I've done that before. | ||
| Bob_thompson |
Just this morning my experience was exactly the same as Xbswede's with the printout. If I had not checked they would have sent me on my way with the old calibration. However after the correct flash the bikes ride ability is much improved as everyone has said. On an interstate ride home of 50 miles checking instant MPG at a steady throttle in 6th gear @ about 4000-4200 rpm's I was seeing 50-54 but not what I ride it for. Have not got that since my M2. No surging down to about 1800 rpm and pulls sharply away in any gear from 3000 even 6th. Heat down about 10 degrees also. Now I must add I'm at 4200 feet here and have not had the amount of trouble others have had but as someone stated even if you think your 2008 is running good get this done. I'm really glad I did. Lovin' it even more now. Next is the solenoid removal and tying the throttles together. Maybe even more improvement. Bob | ||
| Jerseyguy |
My average MPG has gone from 29 to 33. I do have a heavy hand on the throttle though. | ||

well i thought i was able to get in at the dealer here in maine and get it done. but they said they had the new program upgrade in digitech, but that buell hadnt sent the new flash to them yet. they dont know when they'll get it. im confused. i thought it came automaticaly. | ||

I have been waiting in the wings to make sure this flash was the real deal. I finally broke down and took a chance this morning. Here we go; Bike: 08 1125R, June 08 build, 160 miles. Pre-flash: Surge at 3500 RPM. Stutter at rapid WOT from 4000 RPM. No charging/battery issues. Cold start stalling. HOT!!! 182 @ 80 mph, 210+ at stoplight. Fuel smell when parked. Post flash: No surge, even down to 2500 RPM. No stutter when the throttle is whacked. Bike runs 10 degrees cooler at all times. 172 @ 80 mph, 198 @ stoplight. Didn't notice fuel smell when parked. 221 miles. I will try out the cold starting tomorrow. Hot starting did seem improved. I knew when I was rolling through the parking lot that the bike ran smoother. I had the flash done at Manowar Harley in Lexington, KY. The service manager is a Buell guy and has been following this situation, although, I asked to speak yo him before anything was done to my bike, just to make sure we were all on the same sheet of music, and he acted a little put off by it. He did come outside a few minutes later with the letter from Buell about the reflash to verify that his info matched mine and he was real nice. I think maybe he was just a little suspect of internet info and thought I might of been blowing smoke. He said that they just got the letter and this was the first bike they done this to. The service writers are a PITA and do all the standard crap to keep you out of the service area and make it difficult to talk to the techs. The shop did a great job and they did it fast. I'm just not a big fan of the way lawyers make you run a shop these days.I am a former Buell/Harley tech and I preferred to talk to my customers. Thanks to Odinbueller for the advice and for posting the bulletin. | ||

Fellas, Got my ReFlash today. WOW. Its like a new bike in the lower revs. I test road a new CR at the Inside Pass and noticed how smooth it was. My bike is now just as smooth. Heat is down too. In todays weather, it would have got up to 200+. It didn't hardly get to 190 sitting in traffic! All my surging issues are gone. Thanks to everybody for the input and help. And thank you Buell.  | ||

Good post Brant. Just maybe if some of these so called techs would read BadWeb they would be as knowledgable as we are and as well informed. I do not think my dealer techs have even read the "Buell" manual and are focused entirely on HD's only. A while ago while in for the transjet fix when picking my bike up I double checked to see if they had checked the oil level, and even gave them a qt. of what I use in case they needed it. My oil was in fact low and I told the assistant service manager about it and he asked if it was engine or primary. WTF? I put some in myself and finally departed. Good Buell dealers are great as well as their techs. I just wish mine were. Thanks much to all the techs. here that keep us well informed. You know who you are. Bob | ||

Well I just gone done doing a 290 mile loop of mostly twisties here in the Northwest today and I am very happy. A few weeks ago I was getting 27 mpg on these roads. Today I got 37 MPG running mostly in third gear in the 5000 - 8000 rpm range. In a couple of weeks I have a 650 mile trip I will be doing so I will see how it does when I can actually get it in 6th gear and stay there. | ||
| Kttemplar |
I got my re-flash done today and it really made a huge difference. I have just over 6200 miles and the bike is running great now. It seems to rev faster after receiving the new re-flash, but runs awesome. There is no stumbling in the lower RPMs like before. It is hard to tell if it is running cooler, but it ran cooler on the way home than it did on the way to the dealer. Mike | ||

The History of Third Time's a charm Third time lucky Meaning The belief that the third time something is attempted is more likely to succeed than the previous two attempts. It is also used as a good luck charm - spoken just before trying something for the third time. Origin The first time we come across what appears to be a precursor to this phrase is in Elizabeth Barrett Browning's Letters addressed to R. H. Horne, 1839: ‘The luck of the third adventure’ is proverbial. It is listed explicitly in Alexander Hislop's The proverbs of Scotland, 1862: "The third time's lucky. " The 'proverbial' description from the mid 19th century suggest it dates from earlier, although how much earlier we can't really tell. Why is the third time lucky? Again, we don't know. There are a few suggestions. The most common is that it alludes to the belief that, under English law, anyone who survived three attempts at hanging would be set free. This is probably from the story of John 'Babbacombe' Lee. Lee was a West Country sailor who was convicted of the murder of Emma Keyse at Babbacombe Bay in 1885. He was sentenced to hang at Exeter prison and three attempts to execute him all failed. The Home Secretary of the time, Sir William Harcourt, commuted the sentence to life imprisonment and Lee was later freed. He was known thereafter as 'the man they couldn't hang' and went on to live a long life, dying sometime in the 1940s. Fascinating story though it is, the use of 'third time lucky' predates it and thus it can't be the origin. Nor is any earlier reference to the supposed English law on freeing those who survived three hanging attempts. This legal ruling never existed in any general sense and is restricted to isolated cases like Lee's. Another suggestion is that it refers to the Christian Trinity. There seems little to support that idea. It might relate in some way to goodness or luck being associated with the number three, but has no specific link with the third of anything. It seems more likely that it is just a folk belief that, having had setbacks, we ought to persevere and not give up. This is enshrined in the phrase 'try, try and try again'. Three seems to be the right number of times to try. Two isn't enough but four is too many. Think of every time you've seen a drama in which a character tries to unlock a door with an set of unfamiliar keys. The first key fails, the second key fails - it is always the third that works. The same idea is expressed in the American expression 'third time's a charm'. This may be an variant of the earlier 'third time lucky' or it may have arisen independently in the USA. The first citation I can find for it is in The Weekly Sentinel, June 1912. This is in a rather snooty court report about a Mrs. Martha Carliss, who had been twice married previously and 'gave her name as' sixty four: That Mrs. Martha Carliss evidently believes in peace and happiness in wedlock and that she probably thinks third time's a charm is shown by the fact that she was granted a license today to marry Andrew W. Mowery. | ||

Definitely got it right this time. Mine was running great and it's just a little bit smoother now. I can tell because I can easily clutchless shift from 1st to 2nd now. I'm getting about 7 MPG better mileage and it runs 5-10 degrees cooler and doesn't heat up as quickly when stopped. It's a win! Anyone tempted to wait for the 09's I'd say get a deal on an '08 now! | ||

Got mine done yesterday afternoon. WOW! have only ridden 22 miles back from the dealer on the highway, 70-75 mph, filled up at both ends, got just under 60mpg on the ride back....WOW! too bad my son has 2 soccer games today (I coach) so I can't get any ride in today....tomorrow to work and back will tell a new tale  will post more as I experience more bob | ||

LORETTA IS HOME!!! New cam, 5th gear recall are done. I think the 0505 flash got done too, but H-Dnet is being recalcitrant, can't verify. I'm pretty sure it got done, she's almost as smooth at 100/100 AFV as she was before at 95/95. Misunderstanding on the cover to replace and I got a new clutch cover puck. no biggee. I forgot how much power was there, I've been riding Harleys from work to keep semi-sane the past 4 weeks. Even a VRSCR felt mushy compared to Loretta. I can't believe how refreshing the 20 or so miles I got after work were. The Camaro's in the parking lot at work.  Z | ||
| Ccryder |
I feel CHEATED!!!!!!!!!!! I only have two flashes done: #1: charging and fans. #2: Fuel mapping (VERY GOOD if not great) What flash was between #1 and #2????????? Z, glad Loretta is home and running fine. Later Neil S. | ||
| Zac4mac |
Neil, #2 is 0505(I thought), fuel/spark. I'm pretty sure it was done, I think the first was 0502. Z | ||
| Kttemplar |
The current re-flash definitely made the bike run much better. I usually get 29mpg and after this new re-flash, I got 36mpg in mixed traffic and it runs at least 5-10 degrees cooler and very smooth in the lower RPMs now. This is great!!  | ||
| Zac4mac |
I tried to get her into "learn mode" last night. One run up and back on a 4 mile stretch of 45 mph farm road. Still at 100/100 but running like 96/96, almost as smooth as she was at her best. Got up to 190˚ while I idled and set the time and reset the Service Counter. As soon as I got going again the CT dropped very quickly to the upper 160s, AT was 83˚. Gonna take the looooonnnnngg way in to work this morning. Z |
