I just got a LiveWire this week, programmed my truck and I personally love it. Great little device.
There are a few problems with it that I have found, but SCT is working on most of them from what I hear.
1) Contrast display issue, which I believe has been discussed here before
2) Wrong display units on the device. some readings are Kpa instead of standard US units.
3) Oil temperature reading is off.. maybe it's just something minor.
4) IT IS HUGE!!
But, I think some of the qualities and the performance, plus the capability of having a 3rd party company get you custom toonz for your truck is awesome. If you don't have an EGR monitor now, I would purchase the LiveWire just for the capability of having that option. I got mine from Ted and Eric at Innovative and been really happy.
