Took the baby ( 07 XB12ss ) out today for a short shake down run after installing a K&N and a Special Ops muffler. She ran great and sounds really good except for the slight amount of back popping on deceleration so, John as usual, you were right again, I'll need a tune !

I received my Buelltooth this past Thursday but haven't done anything with it yet, they don't list a specific tune for a Special Ops muffler but I have read on here that I can use a race tune. Just wondering if anyone has a specific tune for it ?
 
if you and your pal can ever load it up and get it over to me kenny i can at least install a generic race tune and a short "ride in learn mode" which helps a ton across the board. you must buy lunch!
 
You know what is interesting, I'm more than likely coming down your way to buy an RV toy hauler, sometime within the next week or two. Maybe we could line it up then, I'll be more than happy to buy lunch !

Thanks.

Also, correct me if I'm wrong, as I remember, the worst thing deceleration backfiring would usually do is, maybe clean some built up carbon out of the firing chamber ?

decel "back-firing" is non-existent kenny. mentioned this on here dozens of times before. a back-fire is combustion blowing past one or more intake valves and up into the air intake system....hence the "pop".
after-fire is either combustion blowing past 1 or more exhaust valves and into the open exhaust system....or raw un-burned fuel combusting in the exhaust system and out the exhaust end-pipe. you're experiencing mild "after-fire on decel" when you shut the throttle in gear and coast. harms nothing. just slightly annoying.
 
Yes, it's a little lean stock. Adding more efficient flow through the motor with a less restrictive air filter and exhaust makes it run slightly leaner than that.
The lean mixture in the bike doesn't burn completely, causing the rest to burn when it hits oxygen.Pop pop pop. No biggie, but it will run better with the right tune:up:
 
Under normal circumstances, whatever normal may be, I wouldn't want to have the popping sound but, riding around in the heavy traffic in the Soviet state of NJ, I think the extra noise would be a big help alerting these moron's on their cell phones and driving while dead.

While I certainly appreciate the offer, I'm not smart enough to be able to change a tune, I did take a look the screen shots (it was like seeing the Exorcist for the first time) also wouldn't trust my self. From what I understand though, the Special Ops muffler will work with the Buell race only, tune. I'd be pretty surprised if someone didn't successfully produce a really good tune for it also.

P.S. I just took a ride and I'm already tired of hearing the popping so, it has to go ! I also like the idea of the engine running cooler and the fan having to come on less.

Once you get the tune, it will run better ,cooler , less decel poopping, The fan will oper less, a little more responsiveness and more power. Tim will fix you up .
 
Let me ask this, if I down load a tune from the Buelltooth site would it be the same as sending in my ECM. I ask because I've been reading the instructions on their site and I'm pretty sure I could handle this without screwing up too much. I mean I was thinking I was going to have to change the tunes to tweak them up and all that but I'm pretty sure I can handle what they're describing in the tutorial and, there is only one way to learn.

I already know to save the original tune, in a safe place. I'm going to hook up the Bluetooth later and get the ECM number, and then from there I'll just go along with the tutorial and if I screw up or have questions, my neighbor is a computer whiz. Since I'm just looking for a good tune and they don't seem to make a specific tune for the Special Ops muffler, I'll just go with the race tune, 05-07. I'll let you guys know how I make out, give me a few days, I might have to go back to work tomorrow.
 
If you are going to try and build a tune, I'd use ECMSpy, or TunerPro.

If you just want to download an existing 'Race' tune, ECMDroid is perfect for that. I believe thats all you need to do for your mods:up:
 
While it's not a question of $ and, if I needed a new ECM, I could see paying the $300 for IDS ecm, but at the same time, if I'm reading this correct, it's $200 for them just to load a tune into my existing ECM and ship it back to me ? That seems a bit steep for something that a knowledgeable person could do themselves. Now while I am not a knowledgeable person with computers and such, I do know the only way to learn is to take the first step and since I've already done that by buying the Buelltooth and studying the info on their web site, I am thinking I will take the shot and try doing it myself with a race tune e from Buelltooth, the worst that can happen is I'll have to reinstall the stock tune.

No, I will not be changing things round or remapping, none of that, but thanks for the info.

I'll keep you guys posted on how it goes.
