I know that power balance feature for Ford usually works pretty well on my DS708 with the old version of the reverse engineered OE software . I'm pretty sure I read on forum that the Ford power balance function once worked well on the Maxi Sys with earlier versions of software without having to resort to Imbecilical Cording a USB cord between the VCI and Tablet.I also thought I read there was going to be a Ford software update back last September that was to eliminate the need to have to resort to the USB cable and I even thought support mentioned that relative fuel injector flow test would even be added.
