EFI Live has a learning curve. Time investment is needed to understand the interfaces before you start flashing. It also varies from truck to truck it seems. Mine is very finicky, not sure if all LLYs are sensitive to voltage changes while trying to flash, but sheesh, one little change like just a USB charge adapter and it hangs up mid flash. I have had the "ECM is in an unknown state" crap a couple of times. First time scared the crap out of me, thought I bricked the damn thing. After researching forums, found the cure. It was actually what Rob told someone to do that was in the same boat, worked just fine.
If I had the V2 for 8 months prior to getting any tunes I sure wouldn't let it sit there. The information is out there, just have to search for it (or ask intelligently) and be willing to put the time in to learn it. :thumb:
