WR450R ECU ?

I just installed the programable ECU from Yamaha and noticed that the ECU number on the unit (1DX702M427022A)  was different than the numbers indicated on the instructions (1DX-H59C0-V0-00)

 

The part came with the screw to allow full throttle operation but could this be the unit for the WR250R if there is such a unit???

 

I took it for a ride and it seems normal but I can't tell what it might have felt like.  The ride seemed smoother than my previous rides with the stock ECU but again it may be my imagination..
