both WRT and EE use the exact same bin files. Justin took EE and gave it a 3.0 interface update. He hasnt brought in some of the advanced features but you can take EE, set the advanced features and then do the fuel/ignition tuning in WRT. WRT has a much improved interface for the fuel/ignition. He also gave the community the ability to start tuning many other bikes, including Yamaha and Kawasaki.
