after 2 1/2 years i was ready to call it quits , the popping , stalling , surging and lately lack of power at times was getting the best of me . I do like the bike and it suits my needs but this site has given me hope . I must confess that i have not been here for about a year . last week the bike was back at the harley dealer for the latest ecm upgrade ( about 6 upgrades in the last couple of years and the bike was running the worst it ever has , the only mod was a jardine exhaust , i took it off and rehooked the stock exhaust valve, no real change but the performance was less than stellar and now it starts and stalls 5 or 6 times cold . as per dealer , they could not reinstall the old ecm program even with the old ecm number , I was ready to sell it today BUT now I see that now i can get a race ecm . is it really the final fix ? forgive me for being a skeptic but i'm sure you all know what headaches i've been through , also will the race ecm for a jardine pipe work temporarly with the stock exhaust till I get time to reinstall the jardine . | ||

email Erik Buell Racing first before you order the ECM. Tell them what you are running on your bike, and what problems you are experiencing. You have a couple of choices: Erik Buell Racing race ECM for stock exhaust, pump gas Erik Buell Racing race ECM for Drummer/Jardine, pump gas Erik Buell Racing race ECM for Drummer/Jardine, race gas I don't think they make a specific race ECM for the Jardine, but the one for the drummer should work. And you probably want the one for pump gas, NOT race gas. That's what I am using on my XB12 with a special Ops pipe, Erik Buell Racing race ECM-pump gas, and it works VERY well. Once again, email them, they may be pretty busy with the race season, and all, after all, I think there are only 5 employees. but give them a chance and some time, and they will help you out... | ||

8 employees, but I recommend a Race ECM regardless of what exhaust you are running, as the fuel mapping is fantastic. But about your issue, it sounds like a mechanical failure (IAC?), as it should run smooth as silk with the newer ECM programmings. | ||

I was experiencing the same issues you named off and had the latest and greatest map installed too. That mad my issues much worse, so much so that I gambled on the Erik Buell Racing ecm even though I too was skeptical. It has been less than a week and I've ridden at all speeds and can truly say that the difference is night and day. My 08 is completely stock and it now runs better than ever. Tech@erikbuellracing was very quick responding to my email and just as fast sending my new ecm. As Froggy said, email them and explain your issues. I know they'll help you. Good luck. Bob | ||

I've got to agree. I just picked my 08 up yesterday but the difference with the Erik Buell Racing ECM and the Jardine I've been running is great so far. Popping is gone, smooth power delivery, no more overheat and flooding one cylinder condition. If it lasts I'm hooked. | ||

+1 Erik Buell Racing ECM  | ||

well the ecm was shipped yesterday , hopefully it will arrive here by friday . As per Bartimus suggestion I contacted buell tech , very fast in responding and offered help if all my issues were not fixed , you gotta like that . its a shame that the fuel mappings are so out of wack stock , time will tell what the non EPA approved ECM will do....... hmmm EPA is only in the US not up here in canuckastan . | ||

SERIOUSLY replace the IAC. I posted about it long ago and it solved ALL my problems | ||

I tend to think that your problem is not the ECM mapping, as I have the latest dealer map on my '08, and it run nice and smooth. Those of you that have the Erik Buell Racing Race ECM, is there a noticeable difference in rear cylinder temperature? I'm thinking that with a richer mapping the engine temperatures should be lower... | ||

I should have posed earlier what had been changed in the past year , os sensor , tp sensor , idle valve , fuel pump , injector , ecm , intake seals , also did several compression tests and cylinder leakage tests , all wiring harness checked for shorts and opens , all grounds . all under harley's and the selling dealers bill , the reason why i and buell tech thinks its the ecm map is because , the bike works fairly well hot but still has a slight flat spot at 4500rpm then clears at 5500rpm , cold running with the last map change made it a pig cold unless it idles for a few munites , and it only started THE day I pick it up , evey time the ecm was reflashed over the years the flat spot in the torque curve changed all over the rpm range , please don't get me wrong the bike is not undrivable but it never from new was what i call perfect , the jardine pipe that I had on the bike made it worse so it has been bone stock for the past 3 months like I said this is the last season for me IF the issues are not fixed . ebracing is willing to work with me and I am willing to spend a few bucks out of my pocket to make it right . read my profile and you will see the troubles atarted from DAY 1 kilometer 1 . HD knew about the running issues with the XB and 1125 r series bikes since the new fuel injection system was released in 08 , I will post what happens when the new ECM arrives . thanks for the input it is all noted . | ||

9_ford I had many running and idle issues with my 08XT when I first purchased it. At about 3K miles it started running lousy. The dealer had it for almost the entire winter in 08. They did most of the things you have listed. Sometimes the problem would seem OK until after riding for awhile. Finally the TECH discovered he could change how the bike ran when touching the wires adjacent to the ECM. They replaced the ECM and all issues were gone. The ECM was bad. The bike has run perfectly ever since. It would be worth having your dealer swap the ECM to see if it resolves the issue. There is no reason the bike would run badly unless there is a problem with some component. My 08 runs perfectly from down low to WFO with the latest ECM software. | ||

Did you replace the engine temperature sensor? | ||

no ecm today , it passed custom's late today and should be here to try on monday , bike ran pretty well today except for flat spot in torque at 4500 rpm and kept running first try cold ,some day's with it are better than others . going to put the jardine pipe and filter back on tomorrow . | ||

ecm showed up today . bike still had stock exhaust on but I could not contain myself . first start up it now has a fast idle  , this bike NEVER kicked up the idle on a cold start , up to 2000 rpm then within 30 seconds came now to 1000 and idle without coughing or stalling . since it still has the stock exhaust on I wired open the exhaust valve and took a spin down the road . IT IS FLAWLESS . low speed below 2000 rpm in fist gear is smoother . part throttle letting bike rev to red line showed NO flat spot in the power curve . wide open in second lifted the front wheel about 6 inches and held it to the rev limiter , before it would sit the wheel down at 4000 rpm . the exhaust pipes are noticably cooler on the road . the ebracing ECM IS the real deal ! . I'm going to e-mail them tomorrow thanking them . if you think your bike works fine without it , get one of those ecm's and you will wonder what you did without it Jardine pipe is back on now but it started to rain hard . will post if any change but still starts and idle fine without the cough . My ecm was specificaly programmed for the jardine pipe . it will be fine , I have faith . John | ||

9, ITS KINDA DEPRESSING READING YOUR POSTS. I HAD AN 08 X AND IT NEVER RAN WELL, FINALLY AT 1200 MILES I TRADED IN ON A FXDC FOR 1500 DIFFERENCE SO I DIDNT LOSE TOO MUCH MONEY. BUT A BUELL IS A BUELL AND A HARLEY IS SOMETHING ELSE. HAD THE HARLEY A YEAR AND TEST DROVE A XB12R, NOT MY STYLE. BOUGHT AN XB12XT, LOVE IT, RUNS LIKE IT SHOULD AND LIKE IT BETTER THAN THE HD BUT HAVE BOTH. SOUNDS LIKE YOU GOT LUCKY TO FIND A FIX. I SHOULD SAY MY XT SPITS A LITTLE SOMETIMES AND ONLY HAS 2K MILES, KNOCK ON WOOD. | ||

9_ford, Keep us posted. | ||

My 07 X started bucking and stalling immediately after the 10K service. The techs at HD said it wasnt connected but it is uncanny the coincidental happenstance of the 2 events. Someone here I'm sure can offer some advice or direction. I was told by the dealership that it was no doubt an ECM/fuel control issue. They said it happens alot. Many Buells seem to have wonky ECMs. |
