I am getting the error $0541 when I use my V2. I have only tried it on 2 licensed LS1b PCMs and I get the error on both. Also -- maybe unrelated. All of my .ctz files show up looking like a "Notepad" file instead of having the EFILive logo on them. I have the newest software and firmware on my laptop and V2 unit (V7.5.7.299) (V8.2.2.290) V2 bootblock is (2.07.07) V2 firmware is (2.07.95)
