Gonna leave that post as is. I read through the whole thread and found your most likely problem.
Tune came from Revision Moto.
That right there is 99% of your issue. Want to actually fix it? Get an ecm from IDS (www.idspd.com) that matches the exhaust you have on the bike. IF it actually *is* a Buell factory P&A race exhaust, then this is the part you need to order. https://idspd.com/xcart/buell-xb12-04-07-pa-ecm.html
Install that, do a TPS reset (I highly recommend the CMI-Lite tool, which is also available from IDS) *CORRECTLY* and most likely your problems will be done and over with.
If it still doesn't run correctly after that, then odds are the O2 sensor could be a problem. It does happen on occasion, but not often. As pointed out above, it is NOT a difficult process to replace it.
It *is* a Buell factory race part (P&A stands for Parts and Accessories) and you can run a stock calibration for a very short time, but it will run lean like yours has. It (the ecm) will try adjusting to correct itself, but there is a limit on how much it can do so before finally running like crap.
I am assuming your exhaust looks like this one. https://www.buellxb.com/forum/showth...XHAUST-Muffler
Yes that is the exhaust that is installed.
Revision Moto sent me the tune base on the ECM and that Exhaust info I provided. Are they known to be untrustworthy?
I will gladly run through everything again this weekend, check intake seals, and replace the O2 sensor. No idea why that guy kept repeating that I would refuse to replace it.
I will get a log as well and hopefully that will tell me if anything is still messing up.
I can try the unknown tune that came on the bike since I saved it, but I flashed with the Revision Moto tune with the assumption that was known to be the correct tune for the exhaust. I assumed the previous owner never updated the tune after installing the exhaust.
Shady dave does some questionable ****.
Seriously, if you want it done right, contact Tim at IDS. They are the OEM manufacturer of the ecm, both stock and race units. Physically, they are the same thing but the race unit does not have the EPA restrictions. Get it from a KNOWN and GOOD source. If you can afford the down time by sending in your original ecm, have them do a re-flash on it at IDS.
Hey Dean, just out of curiosity, what do you believe is the matter with rev-mo tunes? They claim to be the factory tunes for each specific pipe, but I of course have no way to verify that. I bought my dongle through him, and used his Jardine tune which seemed to run better, but I'm in no way an expert.
