Just wondering what the difference is between the regular power commander and the non USB one? Is one better than the other and how would I download maps to the non USB??? Thanks.

 

This may not be 100% but i do believe that there both pretty much the same, the only exception is that on the USB one, you are able to add a couple things like the shifter adapter and also something for the fuel pump. to add maps you just need a computer and a serial cable for the non USB and of course a USB cable for the other one...
