So, when I took my bike in to get the clutch fluid issue fixed, my dealer said he checked the ECM and updated it. Since then, my bike is surging more around 3k RPM in first gear than it ever did before and getting the bike moving from a stop requires actual effort because just letting the clutch out causes the bike to die (which it didn't before, used to pretty much just pull away) and adding the throttle is touchy because it goes from lugging to an excess of power, if you know what I mean, with very little movement. So, my questions are these: Would I need to let the update kind of set in with the AFVs adjusting and all? I noticed they are both at 100 now, they used to both be at 105. Would the update affect the throttle issues I've been noting when trying to start moving from a full stop? I checked the TPS and it goes from 2-100 just like it always has. And that leads me into more questions: I've been reading reports about that ECM performance program which must not be named, and people are saying it's been smoothing out the surging issues. Is it really that good? Can the changes it makes be detected by a dealer who isn't specifically looking for them? I ask because my dealer said that changing my fuel map would void the warranty. And, last question, is there any chance that utility has a map for a 1125r with a Drummer? | ||

"Is it really that good?" - Yes "Can the changes it makes be detected by a dealer who isn't specifically looking for them?" - Not looking, no. Looking, yes. One thing to note...the way the program works, it's fairly easy to switch back and forth from the base program to the maps you like. "I ask because my dealer said that changing my fuel map would void the warranty. And, last question," - Hmm, too bad. Many dealers look the other way. "is there any chance that utility has a map for a 1125r with a Drummer?" -Not sure, but if he doesn't, you can do it with the help of a dyno shop. E-mail him and ask.. Mike} | ||

There is not a specific tune for the Drummer... Yet. R | ||

Try resetting the TPS. That may help with the throttle response issue. To zero the throttle position sensor: 1. Set the Run Stop switch to the Run position. 2. Turn the ignition key to the On position. 3. With the engine off rotate the throttle grip from the closed throttle position to the wide-open throttle position and back to the closed position 3 times holding the grip against each stop for 1 full second. 4. Cycle the key off and then back on. | ||

Tried it, no change. It's still extremely surgy, for lack of a better term, and it definitely requires more throttle movement to get the bike going than it did before. That's why I asked about whether the bike needs a few miles to "learn" the new map, which would allow the closed loop to make changes to the AFVs. I'll admit that I'm not the most mechanically savvy, but it doesn't seem that an ECM update should do this. | ||

It will go to 100/100 AFV with the new flash. Maybe see if it smooths out just by letting it learn the new AFV values it likes again? | ||
| Bott |
how many miles since the dealer re-flash? Like Ponti said , the flash is always going to set every bike to 100 afv's. Steady rpm range riding will adjust to your bikes particular needs.Maybe you just havent let it "learn" yet. Hit up a highway and cruise at a steady rpm for a while. | ||
| Easyrider |
there are some lean spots, where the afv will not help too smooth out this amount of fuel with that exhaust. you need to make a new fuel map... i know there are some really good ones.. | ||
| S1125r |
Not many miles since the reflash, but I'm totally put off by how poorly the bike performs in what are all too common conditions given the speed limits where I live. Prior to the reflash my AFVs were at 105 and had been since I got the bike. It was running fine, pulling off the line with no issues and barely lugged unless I was starting off uphill. Now, it dies or looks like I'm squidding it up if I don't modulate the throttle just right. Even if I do it sounds like I'm really lugging it. I'm taking the bike to the dealer this weekend to have them change it back, and if that doesn't work I'm going to start looking at certain alternatives. So, noob questions: what exactly do I need to see what version software is running on it right now? I believe ECMspy can do that, but what hardware do I need? Thanks in advance. | ||

S1125r, What do you have done compared to the stock setup, to get this problem, I try to help you but need to know what you changed, took of, put on.. | ||
| S1125r |
I've added a K&N. That's it past stock and the K&N was on there for 1000 miles before the problem. started. The problem started when I noticed my clutch fluid was black and I took it to my dealer. They said they updated the ECM when they bled the clutch and checked the seals, and since then the bike just hasn't run well below 3500 RPM, really. | ||
| Easyrider |
i think, it's a guess that they disconnected the battery, and then the af was reset to 100 again. there are 2 possibilitys. 1. th current flash is not that good, i have no idea what's in there so it's a guess, but from what i have seen from the latest flash it's not that bad, it runs actually very good, with disconnected 02 sensor's when the af is reset too 100.. 2. your ecm, needs more learning time, go to the higway, and drive 8 miles 120 km/phour then the learning of the ecm is loaded, and then see what happends.. i know for sure, with a new fuelmap and disconnected 02 sensors your bike wil run like hell.. | ||

disconnected O2 sensors? | ||
| S1125r |
No. | ||

Okay, so a quick update and more questions. I gave it another couple of hundred miles to settle in, took a long trip on the autostrada at 120ish kph, and noticed that it was vibrating more at speed as well. The problems with the lugging when starting the bike rolling have smoothed a little, but it's still much more surgy near 3k than it used to be. That's a problem that I can't just live with because many of the speed limits require me to be in first gear around 3k, so it's either smooth that out or clutch the bike everywhere. I'd rather smooth it out. So, onto the questions: Is there a different flash for CA bikes that have the catalyst in the exhaust? What would happen if you put a CA flash on a 49 state bike? Can you even do that? Do European spec 1125r's have the catalyst also? | ||

S1125r why dont you contact dris and see if he has a map for you. They have this service where you send in you ecm along with you specifications and they send you back an updated ecm that tuned to your settings. I'm going to do that shortly myself. | ||
| S1125r |
The dealer I deal with in Italy told me that if I update my fuel map they'll void my warranty. I got the extended warranty, so that's a bit of money lost there. They have the bike right now, so hopefully this problem gets smoothed out. Failing that, I'm putting a new exhaust on my bike and moving away from Italy this winter. You can figure out what might happen then. | ||
| Andros |
YeAh but the ecm update is reversible so you could always get the old map loaded back in there in case you needed to | ||

You know what bugs me about the statement " they will void my warranty if we change the ECM maps" is that 99% of the buell dealers don't even know how to properly update the ECM with new flashes. So how in the H are they going to have any idea that we changed the maps? If they hook up the bike to update the ECM it overwrites the maps you loaded anyway-as i understand it. The diagonistic computer will give them an error code that they won't understand, I have heard the code is something like 255 or something. | ||

S1225R asked - " Do European spec 1125r's have the catalyst also?" Yes, European spec models have a catalyst in the exhaust. | ||

The last time my bike was at the dealer they did me a favor and put in the latest flash. Now my bike also has the surging problem again. I called Buell about getting the previous flash put back in and they told me it could not be done. I'm sure it could be done but they would not let it happen. 50% of my ride to work is at lower speeds through town and it really sucks with the surging and bucking. | ||
| S1125r |
Sportster, thanks for the info. I'll mention that when I pick my bike up today. And Chevy, that's the situation I'm in. Much of the riding I do in town is so slow that I can't get out of the surging zone. Time to start looking at possible solutions. | ||
| Metalrabbit |
Just a question, My '09r has the "surging & bucking" situ at lower speeds but it's a freaking rocket at the upper end,, Is yours the same? | ||
| Easyrider |
maybe, i should come over for 1 year and stay there to adjust your buell's when i hear all the problems.. there is enough work to do...  | ||
| S1125r |
Yeah, mine runs great over 4k. Even better over 6k. The problem is I can't always be over those RPMs, even in first gear. And, I'm beginning to suspect that there might be something out there that will fix my low end surging issues, possibly even make the bike vibrate a little less, and run a little cooler. Hmmm.... | ||

S1125r - The vibration is all but gone in my CR. The dreaded "ignition timing" change got rid of most all of it. It doesn't start to vibrate much till just over 5000rpm. At most cruzing speeds, it almost feels like an inline-4. And I'm still playing with it. No amount of adding or removing gas will fix the vibration situation. Mike | ||
| S1125r |
Vibration isn't really a big worry for me. That being said, it's noticeable and if there's something that will correct it along with my surging problem, then I'm probably going to get it. I'm probably just going to be careful to make sure that I don't take the bike back to this place for it's next service, which shouldn't be a problem since I'm moving soonish. |
