Hi all, I recently bought a 2009 XB12Ss that came with a EBR Race ECM and K&N filter. The PO said that he thought the exhaust pipe had been modded (similar to a Drummer, but not a Drummer). Here are a couple of pics of the exhaust. https://www.dropbox.com/sh/91r6perjhbfnrnq/AABimwv 2rZqpqodpwdso6zL4a?dl=0 I over exposed one so that you can see the weld lines where the PO was saying it had been cut into and modded. My guess is that it is a homemade mod, but I could be wrong. I contacted EBR and gave them the sticker number on the ECM and they informed me that it is mapped for a Jardine RT-1. The issue, of course, is that the exhaust is NOT a Jardine! I’m new to this whole exhaust mapping thing, so I didn’t even realize that different pipes would have different mappings (duh…I know). The bike seems to run fine, but I know that an incorrect mapping can harm the engine, especially if it is too lean. So, my question is – what should I do now? Some options would be to: a. Leave well enough alone since it seems to be running fine b. Take it to a shop and have it dyno tested and possibly remapped (although I’m not sure how they could do that since I don’t know if the Race ECM can be remapped outside the factory). c. Buy a Jardine RT-1 to replace the exhaust pipe so that it matches the ECM. d. Buy a different exhaust pipe and send my ECM to EBR for a remap to match it to that exhaust. e. Something else? Any thoughts you have would be appreciated! Thanks! | ||

Option "A" would be my choice. No the map on the ECM will not be perfect, but it will be better than the stock map, and close enough. Options B through D just add significant cost with negligible gain. Ride it an enjoy it  | ||

Thanks, Froggy!  That helps. Just wasn't sure how "off" the mapping can be before I need to worry about it. Sounds like, as long as the bike seems to be running fine...good to go.  |
