Hello, Bolted a Jardine Slip on on an 04 Firebolt last night, now it barely idles and has a bad hesitation cracking the throttle off idle, runs Marginally better above 2000 rpm's. Called the dealer and he says it needs a Ecm tune for about 500$. Anyone have any experience with this. Only other possible contributting problem is the Battery seems week, have it on the charger at the moment | ||

Do you have the race ECM in it??? | ||

Whenever you change pipes your bike has to "learn" it. Once you've got the battery up, take it out and ride at or above 3600rpm for at least 10 minutes. That will take the ECM into closed loop allowing the bike to "learn" the new pipe. No ECM reset is necessary for changing pipes. $500!  It's $35 here! | ||

Glitch if he has the race ECM in then it'll not run right anyhow. Then he needs to bring it in for a TPS reset and is 35 bucks. If you have the stock ECM in still Glitch is right. Go ride it for 5 miles or so above 3500 rpm's....take it on the highway. If your running the stock ECM leave the servo motor that is on top of you airbox plugged in or you will have a check engine light come on. | ||

Wow, thanks everyone.. That 15 minute ride at 4k RPM's fixed it. Runs perfect now, backfire here and there but that's ok. How funny that dealership is, They said 'I wouldn't recommend riding it very much, we can pick it up for you and fix it' - They just didn't want me riding it around until it ran normal again. Anyway, thanks.. you guys rule.. Here's a couple pics I just took earlier today. Bought it last December. It's an 04, 1900 miles. ..b   (Message edited by 2true on February 11, 2007) | ||

It is going to to take it a bit more time than that as the rear cylinder head temp has to get above 350 degrees. If you are below 70 it will take a while. The best bet is to go ride around for an hour or so and let the ECM monitor the o2 readings in various situations. Good luck. It will get a bit better after a short ride but the air/fuel trims don't really change until it's really hot. Looks good BTW. (Message edited by darkducati on February 11, 2007) | ||

I'd love to hear what is involved in a "$5oo ECM tune." Care to tell us the name of the dealership? | ||
| Bads1 |
They must build a ECM from scratch. Yeah thats it they build a new race ECM.lol | ||

Joe that is a nice bike and a nice neighborhood, I lived there when I went to college at Colorado State...sweet place. I don't remember seeing many Buells there, you must have called Thundermountain HD, affectionately known as Plundermountain to all who darken the door, they rebuilt a sportster I laid down in front of the pickle barrel a few years back. Anyway, I am happy your bike is running good for you, when it gets a bit warmer, with less snow ride the hell out of it, take the Poudre Canyon over to Walden, hit it hard and it will be Perfect when you are on your way back. | ||

I just read the High Country Post...strange that was a decent dealership when I was there...bummer. | ||

Anyone know what modifications are in the race ECM vs the stocker? Just curious... | ||

I'd still go ahead & install the race ECM & hi-flo a/c element. You're running pretty lean right now. You're flowing more exhaust out with a non OEM muffler, and the balance of intake to exhaust is now skewed. The hi-flo a/c element corrects that, but the race ECM increases injector pulse width and adjusts timing & redline to compensate for the muffler & a/c element. The backfiring you mentioned is lean popping, probably on deceleration. I'd wager you're running 15:1 on acceleration & 18:1 on deceleration with that setup as it is right now. The re-learning mentioned before is merely the ECM correcting the adaptive fuel value, or AFV, but it is not completely compensating for the new muffler. The AFV is more for compensating for atmospheric conditions for optimum combustion than learning engine modifications. If you do swap out to a race ECM, you will need your TPS reset. Along with the hi-flo a/c element, you should notice improved throttle response. You may loose a bit of low end grunt, but mid to high range will show increases in power. Hope this helps. Chris | ||

Chris you may be correct and I don't doubt it, but this is my on the road experience. My 2005 XB12R and my friends 2005 XB12R mine with a kit, his without and his will take me by at least a length and a half, we swapped bikes because I have him by about 40lbs and I smoked him with his bike by three lengths more than once. I am looking for a stock ECM to put back into mine. It may be lean, but even with my Race ECM my bike backfires and pops I have worked at and taken the bike to two different dealerships and the backfiring has not ceased. So I would not put a Race ECM in it, I would have it Dyno'ed to see how lean it is, and if it is not too lean as to burn valves..I would let it be. No doubt you are giving the correct advice though. | ||

In all my years hot rodding cars, my general experiences have led me to believe, that an exhaust backfire generally means too Rich (fuel in the exhaust),now if its popping through the intake I'd say its probably lean. I dont think your AF will be very far off once youve had time to ride and let the ecm "learn". It seems the buells are a bit more finicky about the airboxes vs exhaust. If you still have the stock airbox, I think you'll be fine. | ||

Also a little popping could come from air getting in the exhaust pipe from the outside. Like from a small gap between the header and the muffler. I had that problem, it would pop on deceleration. Once I got the gap taken care of, no more popping. | ||

Be sure you repack that pipe when it starts to sound raspy. I've had two Jardines fall apart on me because I'm lazy. I think they should be repacked every 4,000-6,000 miles. I've ran my 04 12R with a Jardine, K&N and the open airbox for about 10,000 miles with no problems. I thought about buying the Race ECM, but that is set up for the race kit so it still wouldn't tune my bike perfectly. The only real options to tune it perfectly are the direct link or a PCIII tuned on a dyno. I believe Al is will tune your ECM according to the mods you have on your bike so you don't have to spend a ton of cash on dyno runs. That is probably the direction I will go in when I have the extra cash. | ||

What Chris Aaron (darkducati) wrote is true. Chris started the beta testing for me on the XB9 Jardine, but we pulled the plug on the testing as we learned how mismatched the 03/04 maps are for the 05+ throttle body/injectors. He has an 05 bike, but we haven't completed that map yet. Soon. Chris and Odie had started some beta testing for me in the early winter months, and the results indicated that the colder temperatures were affecting the ability for the AFV to learn. The engine must be at proper operating temperature for the bike to go from closed-loop mode to closed-loop learn mode. When it's below about 60F, it is hard to get the engine to that temperature when operated in the lower throttle position/lower RPM closed loop learn domain. Odie actually stuffed newspaper in his left side scoop to help get the engine up to temperature to do the map verification on the special ops 12 pipe. It will probably learn OK at 4000 RPM on a ride of reasonable length in steady state operation, but AFV learn at the lower end of closed loop learn mode is a bit tougher to get good results on.

I think I'd call High County and inform them their "fix" was completely off base and a total scam, and you won't be bothering them again for anything, nor will any of your biking friends. I hate crooks that prey on the ignorant (because I'm so often the ignorant one!).  ~SM | ||
| Kowpow225 |
Yes. I'm still curious what this 'tune' would have been. I can't comment on their intentions quite yet but I'd be a skeptic until proven otherwise. | ||

When I put the race kit on mine, I had the same problem. The fix was to take her out on a long highway ride and let the bike calibrate itself. She runs like a scalded ape now. She does give a minor pop or two on hard deacceleration though, but I attribute that to the richer fuel ratio. I also noticed my gas mileage went from mid 60's to mid 40's after this mod. Here again, I chalk that up to increased fuel/air ratio and don't worry about it. I just figure you can either have economy or horsepower, and not necessarily both. | ||
| Bads1 |
Mid 60's?? I can't see that happening out of mine,ever. Serious lugging to get it hey?? | ||
| Tx05xb12s |
Yea it took a lot of petting her around under 3,000 rpm to get that kind of mileage. I once took a highway ride where it was nonstop at 55 mph for 150 miles and she got 68 when it was bone stock! Realistically with my current setup and my usual aggressive riding style, I'm happy with 45. It beats the hell out of 16 on the highway in my 4x4. Trailering my bike 885 miles to MBIV is going to suck! $$$ Worth every penny though. |
