Modify right or GTFO.

My Buell is outfitted with an exhaust and matching ECM and I do not get much decel popping if any at all. However, I see videos where the XB is popping and sputtering all over the place. Am I lucky and have a rare modified XB that does not decel pop, or do these guys not know how to modify a bike? ...............Thinking back, I do not recall my XB ever decal popping when it was completely OEM either. The only time it popped really bad was when I had an exhaust and no tune. I guess I answered my own question. Modify right or GTFO.

I'm certain that in order for you to have accomplished your near perfect tune you spent a lot of time data logging. Or at least someone did. Problem is people aren't researching how to accomplish what you've achieved and are trying to either flash an entire eeprom or someone else's fuel mapping on their ECM. Either way, if someone doesn't know what they're doing it's a terrible idea to do either of the two methods just mentioned to "tune" an xb.
I takes a lot of time, knowledge and patience to achieve a customer tune for an XB.
NO ONE was giving that away over a decade ago and it seems no one wants to give that away today.
When talking Buell there's no "quick fix" out there for tuning issues.

I'm using an EBR ECM so I don't know if that qualifies as a "near perfect tune," but some of these XBs pop and sputter so bad I am convinced all they did was put a pipe on and did nothing to the ECM.

My 2009 XB12R with a Jardine Exhaust and compatible tune (done by the PO) pops so bad, it is annoying. I flashed the ECM with the "correct" tune and it made no difference. I have been told (by folks here and on BW) that there is nothing I can do except change exhaust and remap). I've been doing a lot of logging, but have not had the chance to examine the results. I am saving the funds to have the stock can modified by Dean Adams, which I was told is the best way to go anyway. My S3 has the Race ECM and Vance and Hines SSR2, with no popping or issues at all.

Not sure if dean does mods to stock cans http://ecommerce.deanadamsdesigns.com/index.php?cPath=22&osCsid=c9b7939b20f73380ba0977fe45169999 just to mention a few Hawk,special ops ,drummer, force they do stock can mods.

EBR does remapping also http://www.erikbuellracing.net/store/models/xb12/xb12-preprogrammed-ecm.html I am running Deans pipe with a IDS mapped for a D&D which is similar cal helped with the decel pop. Waiting for EBR to do a CAL on Deans pipe then they will remap my ECM.:eagerness:

I guess I shouldnt be holding my breath ! I would be dead and buried last year.:black_eyed:

This reminds me, I have a spare IDS ECM for 08-09 XB 12 with Drummer SS if anyone is interested.

 

[airbozo]

Sorry, meant Drummer...

K.I.S.S.

Decel popping is usually caused by a slightly lean de-cel condition (adding a muffler without a 'tune' will do that), or a leak in the pipe. Fix those = no popping.

There's no need for a completely custom one-off injection program and the $1000's you'll spend to get it for something that minor.
It's not magic, and these bikes haven't changed since the common programs have been available for so long now. There's lots of variables... like maybe your program isn't right? Since they have been open source for so long, how do you really know it is what they say? You get what you pay for.

If you're decel-popping regardless of tune, you likely have an exhaust leak.

In my case I flashed the proper map, just in case. The PO said that it was popping on decel since the day they installed the Jardine (and flashed the ECM) and everyone I have mentioned that to says it is the can. He sent me the original muffler at no cost (even paid for shipping). I do have a leak where the can mounts to the header, with springs no less, and I have been trying to fix that before I swap it out. I am going to have to pull it and apply high temp sealer. Hopefully soon, if the rains let up.

Why would anyone use springs at that point? I see them on sport bike exhausts all the time, but never felt they sealed anything all that well. Am I missing something?

Getting cage crazy. It's been too cold and/or wet to ride and I'm going NUTZ!
