Thanks to Odinbueller's post on the ECM update/reflash, I humbly stand corrected.  JJ | ||

"the million dollar question is why are some electrical systems seemingly fine and others not working. " You could pose that very same type of question concerning most anything on planet Earth. Why are some things the way they should be and others are not? Hmmmm... The answer is... "variables", or in the most base of laymens' terms, "shit happens." Get over it. Move on. Occupy your fine intellect with other more gratifying issues, like for instance which way to install and orient the roll of toilet paper in your bathroom. | ||

well i went back home at dinner yesterday and even though it went right up to almost charged soon after i hooked up the charger in the morning, it still didnt read fully charged when i went back at dinner. although the bike did start up ok. all my lights and the gauge flickered for about the first 5 miles though once i started riding it back to work. all the connections looked good. we did just reflash it a bit ago today so i have yet to see how that works out. guess i'll just leave it off the charger now and see what happens. | ||

I am still skeptical about the new FLASH. I have it and I still have the charging problem. My dealer called BMC a week and a half ago and still no word. I still ride everyday to work and the battery hasn't discharged in a while "it hasn't been sitting". I have to repeat this: it has discharged even with the latest and greatest flash. | ||
| Blake |
When did you have your ECM reflashed? | ||
| Fresnobuell |
The answer is... "variables", or in the most base of laymens' terms, "shit happens." DOn't buy it. SO Blake, what happened to your "system is fine as designed...any faulty electrical system is component-related?" Guess not, huh. | ||
| Reepicheep |
If they solved many problems with an ECM reflash, and didn't replace a single part on the bike, then it doesn't sound like the fault was component related. It sounds like some variables emerged based on final production bike variances and / or particular usage scenarios that were causing a solvable strategy problem in how the ECM operates the various bike components to optimize durability and performance. Its really hard to test things that are being built. Think 20% of the total budget and 30% extra time for your project to just do a bad job at it. And thats for software, where you run it to the point of total failure and just reboot. We don't have to sweep up shrapnel, put out fires, and clean oil off the dyno drums  | ||

The charging system was and is fine as designed. The ECM programming benefited from an upgrade. Whether or not that will resolve all current and future 1125R depleted battery issues remains to be seen. We do know for a fact that a number of such issues have been resolved by one of the following diagnoses and applicable resolutions: 1. Battery not fully charged upon delivery; resolution: charge battery fully. 2. Failure to follow required shut-down procedure (kill switch to off then ignition to off); resolution: follow shut-down procedure specified in owner's manual. 3. Faulty stator; resolution: replaced stator 4. Faulty voltage regulator; resolution: replace voltage regulator. 5. Faulty battery; resolution: replace battery. 6. Faulty electrical connections; resolution: clean/tighten electrical connections. | ||

Keep on Blake. Hopefully I'll have mine flashed tomorrow. Bumpus has already done the "shop" bike (read the Owner's) and they said to drop on by and they would work it in quickly. It only takes less than 15 mins., start to finish. It sure is nice to have a GREAT Dealer! Neil S. | ||

If you own an 1125R . . read Blake's post carefully. While the pundits are pointing, guessing and conjuring up conspiracy theories there are a team of fairly astute young engineers diligently working on the 1125R and following up on issues. The 1125R reflash is an amazingly rapid (for any motorized vehicle company) response to real world owner input. If your dealer has ANY problem getting information or trouble finding the information on HDNet (someone screwed up and apparently mis-filed it) point them to this thread for data. If questions remain ask them to contact S.P.O.C. . . . again there are tremendous resources being devoted to the 1125R. Court | ||

Consider mine resolved! As you might remember from my previous posts, my issue was with the bike not charging at idle when the coolant temperature exceeded 185. Got the flash today and promptly got stuck for an hour and a half in stop'n'go rush hour traffic on the way home. The tell-tell voltage meter I had added to to manage this issue told the story. The ECM update worked. Temperatures were in the 80's, coolant temperature reached 200, but the voltage meter never dropped below 12.5. Prior to this idling for 20mins or more anywhere north of 190 CT guaranteed a drained battery when I got home. Today, voltage was 12.8 when I arrived home.  | ||

Spectrum, did you notice any difference other than the volts not going low. I was wondering if it will shut off one of the fans if the voltage drops too low and that is how the charging system can keep up. I noticed that the program said that the fans can be controlled independently with the new program. | ||
| Spectrum |
I did notice some pitch changes in the fan noise on occasion. I had not heard that before the update. Not sure what that equates to or even it was just my imagination. I really haven't had a chance to pay much attention to the fans yet though. I'll look at them more closely over the next few days. | ||

Well guys, I finally am in your club. Went out to take a ride, turned the key and everything sounded and looked fine till I hit the starter button. Lights went out, headlights(normal) AND dash(not normal). Starter relay clik-clik, not going anywhere yet... DM in Park says 10.1 volts. Last ride was Friday with a couple of hours trying to get the flash to take. She was on a tender for most of that tho. Maybe she's jealous, I did ride the Shovel a little yesterday. Zack | ||
| Spectrum |
Zack - I'm not going to add you to my charging system tracking issue spreadsheet unless you say other was. I'm assuming they ran your battery down trying to do the reflash. | ||
| Zac4mac |
Yeah, probably not. Although she was on a Tender, that doesn't replace electrons as fast as the lights are draining them. She's on the Tender now, took 3 hours to go green. Started fine when I headed for home after the reflash attempt. odd. Moot point, I'm inline for the flash as soon as they can make it work. Z | ||
| No_rice |
im not so sure i like the reflash. mine seemed to run better before. it wasnt extremely smooth down low at cruising speed, but now it seems alot more rough down there. | ||
| Thurstonbuell |
No Rice, I agree , mine seems to surge and hic-up for no better term at low cruising speed , never did that at all before , made me wonder if I should have had it done , also made me wonder if the ECM has to re-adjust mapping or something , rode close to 100 miles since the re-flash , and it might be getting better , but too early to tell...... | ||
| No_rice |
i put on a little over 100 yesterday. most of which at cruise around 75mph, rode it to work this morning and it is real rough. even up to 4000. feels almost like im blipping the throttle, lol. | ||
| Zac4mac |
From what I understand, after the reflash, the Adapt Fuel values go back to 100 and the DDFI III has to "re-learn". Take her out and HONK on her. No need to be "gentle" once break-in is done. Hopefully I'll get the flash in the next day or two and I can verify it myself. Z | ||
| Thurstonbuell |
I think mine is only rough upto the 3000rpm range , I was on our local motorcycle run yesterday , alot of stop n go , alot of low speed cruising , was really getting kinda annoying , but did seem to improve slightly , or maybe I was just getting used to all the surging , I was hopeing with all the low speed stuff it was learning fuel value's ??? | ||
| Spectrum |
According to the ED Manual. Adaptive learns from stead RPM's below 4200. | ||
| No_rice |
hmm, guess i will have to go for a SLOWER long cruise | ||
| Thurstonbuell |
You can do it No Rice , It'll be grueling , but you can do it , just exercise some self control , count backwards from somewhere like one million , and keep reminding yourself it's for the good of your bike (Message edited by Thurstonbuell on May 05, 2008) | ||

Did anyone ever figure out what was killing the battery on these bikes? My battery just went dead for the first time, the bike just sat overnight and was dead the next night. I rode it all week, above 3000rpm while riding, completely stock no extra electrical devices on it. No slow crank or anything else up to the dead battery. It had the reflash done already. I have not had it on a tender and the battery voltage was always 12.4 or greater at rest. The voltage was 8 volts last night. I'll do some test on it tonight but I just was wondering if anybody ever found the magical battery killing part on these bikes. | ||
| Bobup |
I have not had any problems since my ECM was addressed.....this had been my thread originally....so as far as I am concerned...it is now a "dead" issue....sorry...had to do it | ||
| Fresnobuell |
Chevy, unfortunately.....no. Same thing happened to me about 3 weeks after purchase. Several theories floated about, but nothing was confirmed. I would still like to know the source of the problem cause the next time it happens it will be someplace very inconvenient , I am sure. Bizarre. | ||

FYI. Another 'dead battery' data point. Had the reflash done a week ago. After the re-flash, the battery-low indicator lit when I got home from dealer (14 miles @ 70 MPH). They confirmed they had the bike turned on, and not charging, for 'a while' during the re-flash. (I sat in the 'waiting room' over an hour). I recharged the battery at that time, 2 Amps/12 volts for a few hours. The battery-low indicator extinguised during normal riding. Rode the bike about 15 miles after charging it in the previously mentioned fashion, and after that, haven't ridden the 1125R in 7 days. Went out to start it just now, and the battery was kaput. No headlight, dash lights, etc. I do hear something energizing when I turn the key to 'On'. Maybe the fuel pump. Last time I rode, a week ago, I shut down per usual, i.e. via the recommended procedure, with the 'Run' switch to no-run. Maybe the battery never came all the way back, after the re-flash (?) That's what I suspect. It's on the charger now. I didn't measure the voltage prior to beginning the charge. However, the charger charging-scale, which shows relative current being provided, indicated the battery was pretty 'low'. This is consistent with 'no lights' when the key was turned on. I hadn't performed any diagnostics, etc. In fact, it's gone unridden this long several times prior to this, and not discharged. This is the first time since I've owned the bike (Feb/Mar 08) that the battery has died in this fashion. I'll follow up with other posts, from time to time, until this is resolved. | ||

Alan, About the same series of events for me. No problems till reflash two weeks ago. Rode home from work in 120 degree heat blowing off of the interstate. Bike then set for two days. Would not start for work. The battery light was on at power up for a couple days previous to the hot ride. No problems before the reflash. I think that may be just a coincident though. Could it be related to the heat. --- You can bet I will heed the battery warning light next time! I do love this bike though. What a short wheel base hotrod. Hope I don't forfeit my license to a reckless charge, ie serious over speeding!!! | ||
| Alans |
Update to my previous post. I charged the battery ~12 hours @ 2amps. Just got done hooking-up a Battery Tender (1.25A/12v). The Tender has been charging now about 1 hour, and the BT indicates it's still charging. Though, the BT also indicates the battery is 80% or more charged. The bike is rideable now. I plan to use the Battery Tender from now on. I've done this with other bikes, and don't personally find it out-of-the-ordinary to require the use of an external device to keep a bike-battery topped off. I might not ride a bike for 1 to 2 weeks. And then, it could be a short jaunt of not more than 20 to 30 miles. With the BT in my process, I don't expect the battery to die again as it did this last time. At least, not until it's reached its service life. |
