the software is not needed it is there to make the tunning easier and and cut down time with the commander you have to toggel down or up to change things in stead of a mouse. And even if you had your hands on any of the stand alone ECU you would not be able to tune it because your Jack B. All you have to do is call Apexi and they will set you straight. Hmmmmmm, this kinda remindes me of you and MotoRX and we know what happen next. :)
