I finally got the software to hook up to the tractor. It is a 2013 Volvo with version 3 electronics using OBD. I am trying to alter the roadspeed on the fleet. And I am having a very difficult time with this software. I can not locate where it is adjustable. I see about every other parameter to change in the world. There must be over a 100 of them. but no road speed that I can see. Any help would be greatly appreciated. Thanks.
