ECM can be updated to 2010 specs, BUT, you have to do the fuel pump as well and a couple other things, I think. Email [email protected] and ask Dan what needs to be done.
DDFI-3 tuning with stock o2 sensor

Help Support Buellxb Forum:
AZ it is just a matter of wiring the new sensor to the pin 31 on the grey ecm connector. And after enable the front cylinder closed loop on Ecmdroid or TunerPro, both will do.

I confirmed this does not work today
Pin 1 = front afr
Pin 31 = O2 sensor 1, model year 2010
Pin 32 = O2 sensor 2
Pin 33 = rear afr
All on the grey connector. If you want both O2 sensors to work, you'll have to upgrade the ecm to 2010 specs. The widebands send data, but the ecm will not actually utilize it. Record it, yes, use, no. This also means you have to upgrade the fuel pump though. Email EBR if you want to pursue it, they (Dan) know what you need to do.

Correct Dean.
Although, I believe you can still do it in the 08-09 firmware, but you need to know how to edit the xdf in TunerPro so that you can enable it. Other than an error mask, there is no options for a front O2 sensor in ECMDroid.

Did you make the wiring to the ecm and it didnt work?
I talked to a guy from badweb that made this to his 08 XB and he told me it worked flawlessly. He also forwarded me his .bin eeprom file.
Actually ECMs starting in 08 are already "2010 specs" since the hardware is exactly the same. It is a matter of wiring what is necessary and making the changes to the eeprom, but hardware speeking, they're exactly the same.
The stock ECM in my bike is BUE1D and have a spare one with BUE2D. Both have the option to turn on front closed loop inside TunerPro.
Actually there is the option already mapped on TunerPro.

Yes, I wired it to the ecm.
There is no options, in ECMDroid. I have looked in TunerPro before, and 90% sure there is no option in the standard .xdf files to enable the from O2.
The 2008-2010 ecms are the same hardware wise, but not firmware. BUE3D is the only firmware with dual O2 sensors enabled. Like Dean said, you can have this firmware flashed by HD, or you need to modify the .xdf to enable the option of turning on the front O2. Which I don't even see that in the breakdown of the hex code on ecmspy.

Each firmware that supports a front AFV also supports (has to support) an independent front CL. E.g. http://ecmspy.com/cgi-bin/detail.cgi?ecm=90&offset=368
That doesnt make sense to me since back in 2008 1125 models already had dual oxygen sensors, dual closed loops and BUE3D didnt exist yet. And they shared the same ECM with the XB models which is Y0152.1AM. Same hardware, same firmware.
In a 30 minute I'll get to office and send you a print screen of what I think is the command in TunerPro to get it enabled.

Looks like I was wrong, and missed it on both ECMSpy and TunerPro
If you succeed please keep us posted. My project of installing the front bung is delayed as I thought it was better to remove the header for welding instead of doing it in place.

I'll attempt it again this weekend, and let you know how it goes.
How did it go? Were you able to give it a try?
I have just faced something weird, at least to me, so I´ll go ahead and ask you guys.
I got a spare ECM here which came from a 2009 1125 with BUE2D firmware. When I downloaded it eeprom I realized its fuel maps have higher resolution than mine BUE1D. However, a very nice guy from another forum supplied me with the eeprom from his bike which is exactly the same I ride: 2008 XB12x. He had his ECM reflashed at the stealership a couple of months ago and he assured me it is completely stock. I opened up these fuel maps and realized they´re different from the 1125 in which they have different resolutions. Even the BUE2D map for the XB12 has lower resolution, identical to my BUE1D. Only the 1125 BUE2D has higher resolution. So my question is: I think I know the answer, but anyway, is it possible to "create" new RPM colums on the XB eeprom to make it equal to the 1125? If it´s not, which I think is the answer to the previous question, do any of you tried to remap the 1125 eeprom and ride it on the XB?

Yes, you can change the resolution and rpm values in TunerPro. DDFI3 all have the same size map, but they don't all use the same axis. You need to just enter all the rpm points you want in the fuel map axis table.
Never tried a 1125eeprom on a XB. I have been told none of the softwares read or write all of the pages of the eeprom, and not knowing what is on those pages would be enough to kept me from trying. If you can read and write all the pages, you can change the firmware. I'm sure Gunter knows if it is possible or not. Sure wish he would release his next version with firmware update to the public.

Didn't get around to it
AZ, are you sure TunerPro let´s us change rpm values? I couldn´t figure out how to do it. Check the screenshot below:
There are three greyed buttons and the first one reads "Edit linked X-Axis table" which perhaps is the function needed to change RPM values. However it is disabled, can´t use it.
