I have a 3k surge/flat spot, starts good, runs fine 'when, ON IT' but doesn't like to cruise >3-4k< it is dead stock 2010 XT, (Racing Red, BTW, and did TPS reset and 3k-30min cruise) wondering if as per, Pkforbes87, '...the EBR ECM than any other modification or farkle I've performed on my XT....' and '...SO much smoother. Never has a hiccup at any RPM,..' is a solution, considering, it has what I think is the unique/last year, front bank (2nd) o2 sensor, (relevant??) what-d-ya-think? EBR ECM ? if so which one? or ECM Spy? or something much simpler? (Message edited by jeepnh on April 30, 2012) | ||

Hey Belinda, let me know how your install of the new ECM goes. I just tried to do mine on Sunday with the mastermind RonMold of baracade orange ilk. It didn't go so well. I rode over to Ron's house so the bike was very warm. We plugged in the new ECM started it up, the bike was spitting n coughing, running really rough. It took us about 4 long minutes to set the TPS, which helped it then, I let it idle for a bit and then made the mistake of shutting it off. Tried to restart the bike 5 mins later and I had a fouled plug. Kept trying to reignite the bike and it wouldn't start, now the battery is getting low. So we put the old ECM back in, got the jumpers and marine battery out, it just barely started, but then I rev'd it up and took it down the freeway til I got home. It seems like its back to its old self again. I'll try to pop in the new ECM tonight now to see what results I get. Now that the new ECM has the TPS set, I'm hoping all it needs is a little riding. I'll keep you posted. I'd also like to give a big thanks to Ronmold for breaking out the ECM spy program and helping me. He's a great guy and knows a sh** load about bikes. Very glad to know him. Plus he rides a Uly - though I think you need to ride it more Ron! | ||

Will keep you posted, uly dude. We are anxiously awaiting the arrival of the big brown xmas truck, should be here sometime early afternoon. It's been awhile since the xt has been functioning properly, hopefully this makes a positive difference. If there's any lemons into lemonade aspects garnered here, it's the appreciation for the uly X I did not have previously. I am seriously considering taking it, not the xt, to MN this summer. | ||

Its odd how engine problems differ. The only running problem I had on the 06 Uly was the sub frame ground issue which in my case caused the timing not to adjust itself as the engine heated up. Once this had been fixed - stock it would idle/run right with no flat spots. It was the same with the a Remus can/K&N air filter and open air box. The addition of a Remus Powerizer boosted fueling to the low/mid rev range and gave more power. The whole thing ran very well with little vibs. I could run it around town at 20mph in third, 40mpg in town and 50mpg+ on the highway. Thats UK Galls which is 4.5l per Gall. I think US Galls may be less than the UK one. The cold startup is done through "fuel enrichment" which can be changed with ECM-SPY. The bike always ran very hot though but even on 30C plus days in "stop/go" traffic I had no problems. "I have a 3k surge/flat spot, starts good, runs fine 'when, ON IT' but doesn't like to cruise >3-4k< it is dead stock 2010 XT, (Racing Red, BTW, and did TPS reset and 3k-30min cruise) wondering if as per, Pkforbes87, '...the EBR ECM than any other modification or farkle I've performed on my XT....' and '...SO much smoother. Never has a hiccup at any RPM,..' is a solution, considering, it has what I think is the unique/last year, front bank (2nd) o2 sensor, (relevant??) what-d-ya-think?" Its VERY relevant. Your bike should run perfect. It should also run MUCH cooler than the early bikes and the idle is controlled by a electro-mecanical system. I had a problem with my 2010 bike and the dealer changed the ECM with no result. They then did a logged run and sent the results/data to HD who said it was a faulty O2 sensor. Bike runs great again. The DTFI-3 system may or may not have a faster chip/more memory but I think it might have. It does however have a better program than that on a 06 bike. | ||

It has arrived. New ECM installed, tps done, ran for ten minutes. So far so good. Now its time to take it for a ride. Will report back soon, hopefully all's well in XT land. | ||
| Buelldualsport |
Good On you Please let us know. Ride Safe | ||
| Fltwistygirl |
Wow, what a difference with the ebr ecm. It is way smoother than before. The high idle at start up will take a little getting used to but I can live with that. Gonna try to make sure I get it out a couple times for at least an hour or so to make sure the ecm replacement takes care of the issues I was having. | ||

Thanks for the posts. I can't wait to get mine in. | ||

hard question to answer seriously. hard because if i hadnt put the EBR ECM on my xt i would have gotten rid of the bike just like i did on my first uly which was an x. almost gave it away and was glad to see it go, coughed and spit so bad it was unrideable. ok, sure probably there was some dealer problem there cause the dealer literally said "golly gee" when i showed him the thing, learned later that this salesman was making a mint reselling used buells traded in by unhappy customers like me. BUT, i missed the monster and bought an XT, it too started doing the coughing crap but thanks to the forum i choked up the cash for the ECM and havent looked back since. it runs like it should have in the first place. just for grins i put on the factory ECM some time ago and couldnt make it around the block without "the problem". i still believe that a large part of the problem is the mounting of the unit and so when you do plunk for it, REMOUNT THE SUKKER some where out of harms way. | ||

An interesting point. I know a dealer, Buell or otherwise, will try to re-flash a ECM first if they think its at fault and change it out if it will not take the re-flash. This is because the ECM can become corrupted through bad data input IE like your computer which is what it is, and could cause the ECM not take a re-flash if the EEPROM is not protected. They can be very sensitive. I am getting real scared now? I always knew the system was slow and basic but I am now getting the impression that the prog itself may have bugs in it and/or be badly coded. If you look at it in a logical/computer way, given some faults it works. I do not have the tools to prove this but something does not seem or feel right to me some how. | ||

Uly_man, thanks for your insights, Yep, does run cool, fan cycles very briefly only when I ride it hard. BUT, but still doesn't like to cruise >3-4k< 'riding politely' = ugly/uncomfortable surge/flat spot, so bad making my lady passenger uncomfortable, verging on anti-Uly. As mentioned, starts & runs fine 'when, ON IT' I've read about a lot of this, 3-4k RPM stuff, and trying to figure out if 'nature of the Beast' or is it fixable? I've considered 1) Race Muffler, partially 'cause of nicer sound, and/or 2) Getting into 'ECM Spy World' or Race/reflashable ECM. I just don't want to get ahead of myself with 'stuff' and miss something basic/obvious. Sincerely, thanks for any thoughts. | ||

Jeepnh, from your last post i gather you dont have the EBR ECM installed. GET ONE!, you wont regret it. especially if you share the bike with other half, girls arent in to horsepower like guys and the upgrade gives really good performance and tames the hiccups etc. yep, i still got a really small flat spot around three k, and yep, buells LIKE to get romped, thats what they are valve tuned for; its a mechanical thing more than electric at this point. I ride mostly in town and traffic, the EBR (for stock exhaust yet) makes a world of difference, without it the bike was only good for flat out highway running. | ||
| Fltwistygirl |
"girls arent in to horsepower like guys" Ooooh, danger, danger! This is incorrect. | ||
| Buelldualsport |
Indeed Incorrect Ask John Force | ||

Thanks Gringo, Much appreciated info, trying to help me 'fix n fiddle with things' ..... :-) (what boys do) Easy girls, I'm sure Everyone here is appropriately PC, and would Never tread into any Gender sensitive 'zones'.... Just for giggles and clarification, even as we dabble into mixed doubles Road Racing, part throttle smoothness is a little different than Horsepower. Side note, as I'm teaching my lady how to drive a stick shift performance car, her words, '......'oh yeah! 3rd gear is your friend....' | ||

Can you reset the TPS with an EBR ECM using ECM Spy? Either I missed the answer to that question or it wasn't answered. I'd also have to ask them which of their preloaded maps would be best for my bike since they dont have it listed - 06 Uly w/Hawk Racing pipe, race air filter and modded airbox. | ||
| Ksc12c |
I have an 06 Uly with the stock pipe. It has a cracked ECM and suffers from the occasional Skip/Spark issue. I purchased a EBR ECM. I sent EBR an e-mail requesting which one to order for the stock pipe. They replied to me and said to order the "Pro Stock Series" ECM. I installed the ECM and had no choice but to do the TPS reset using ECMSpy. I was able to do the reset with out issues. To be honest, I didn't seem to see that much change in performance and maybe little less gas mileage then before. It also kept throwing the CEL on and off every time I rode it. I got so frustrated with it, I just pulled it out and went back to the old cracked ECM. I need to replace the cracked ECM and I'm looking at two options. The first one would be go out and by a Stock ECM have the dealer flash it and take my chances the dealer won't screw it up or upgrade to a Drummer and Drummer ECM | ||
| Uly_dude |
another option would be to throw the CEL again and this time find out what it was. Might even explain the gas mileage thing. If there's something wrong with the EBR ECM, they'll usually reflash it for ya. | ||

I also have a 2010 Uly, an X. Been thinking about chocking up the money for this upgrade. Still don't have myself convinced mostly because I'm not very electronics savvy and am intimidated by the tps reset. When the bike was still under warranty, the dealer did a bunch of work on it and did a tps reset...WOW, what a difference just that made. So, how does a person go about doing a tps reset? | ||
| 1313 |
12x9sl, On an '08-'10 XB (and '08-'10 1125's) the TPS procedure is VERY simple:  Thanks to DDFI 3, 1313 | ||
| Fltwistygirl |
"the TPS procedure is VERY simple" +1. I keep notes in my phone that list these steps. It takes longer for me to pull them up on the screen than it does for the actual tps reset. | ||
| Jeepnh |
I see this TPS Reset procedure referenced, A LOT. Is it really handy/useful if you aren't changing hardware? I thought the ECM 'Learned' stuff, and self adjusted. I thought (innocently/naively??) that Throttle Position Sensor-Reset, was just for resetting a new base (Idle Stop) point. Is the Buell community's experience that it is useful on a routine drive around the country-side?? | ||
| Buewulf |
Is the Buell community's experience that it is useful on a routine drive around the country-side?? It is useful to be able to do when things go awry and you don't really know what is causing the issue. Reseting the TPS is easy, so it is good to be able to perform the procedure and eliminate that possibility if nothing else. During my unscientific perusal of issues and mental note-taking on them, I'd have to say that the vast majority of problems are not resolved by reseting the TPS, but every now and then they are. So if something seems off, give it a shot. Worst-case you lose 15 seconds of your life. That is my 2-cents, anyway. | ||
| Froggy |
It can be. The TPS is arguably the most important sensor in the fuel injection system, as how much gas is squirted into the throttle body is determined directly by the TPS reading. The TPS reports how much you are twisting the throttle, and therefor how open the air intake butterfly valve on the throttlebody is, then the ECM tells the injectors to fire for X milliseconds. Given how important the sensor is, it is good practice to reset it first if the bike is running funny.
On the 08+ bikes, it does learn and periodically recalibrate the sensor, but there is always a possibility that an issue has arose and forcing a reset could fix it.
Like I mentioned above, it does that and more.
Pretty much never, but given it takes 15 seconds to do, it can't make things worse. | ||
| Jeepnh |
TPS Reset, Well said, understood and appreciated. Thanks, everyone BTW, related hopefully not an intentional hijack, my '10 XT has a, late addition, second O2 sensor, does that mean: 1) will it 'learn better' 2) confuse or even 'talk to', EBR ECM ? It is remarkable and hard to describe to the uninitiated, the wonderful level of community support here, sounds corny, but what a great group!! | ||
| Froggy |
1, Yes. The older bikes with one sensor would take a reading from only the rear pipe, and then adjust the AFV for both cylinders. The second sensor allows it to adjust both cylinders independent of each other. 2, If you go to EBracing.com you will see they have a dropdown to specify 2010, this is due to needing slightly different programming for the second O2 sensor and new fuel pump. | ||

I installed my EBR ECM the other day. I reset the TPS while warmed up. (160 degF). I have an open airbox, Drummer exhaust. I have not noticed any significant improvement. It doesn't have a high start up idle as mentioned by others here. I still get the 3K hiccup, and decel pop is still the same. Did I miss something? Not really seeing any improvements over stock. | ||
| Buewulf |
Did you have the drummer and air box before you got the EBR ECM? If so, then I would assume your maps were not stock. So I wouldn't expect an improvement if that were the case. | ||
| Andrejs2112 |
My maps were not stock. I had done the "square idle" mod and had a few tweaks done by another member here. I just assumed that the EBR ECM would take care of the 3K hiccup and bump my idle up while cold. |
