Yep, you need different software for DDFI-3 ecm's.
www.tunerpro.net
Tunerpro RT, the buell io-plugin and then whatever xdf file matches your bike's firmware. Not sure what cool code and mapping stuff it is you want to do, but that's what you'll need to get started. If you're planning on doing some data logging, you'll need an adx file as well.
Check with www.xoptiinside.com for more info.
Btw, if you do mess with the race ecm, it will void your EBR ecm warranty if you still have one.
