I had the same issue - couldn't see any analog voltages in Scan Tool, when they were showing on the FlashScan V2 fine. Is there a solution to this issue?
Hadnt had any problems for a long time, then the other day went to use Scan Tool and got the "not compatible with this firmware" type message and was forced to do the whole Firmware / V8 / V7.5 update dance again... wish i could have just been left alone and not bothered... but ended up losing the external voltage feature for my LC1 which had worked just fine before. Now I have a new issue though
I tried the build linked above but it was "404 error"d so I tried the Sept2015 build then got the Response $03 error and couldn't connect to the vehicle. Yes, the firmware and bootblock is ok per v8 check tool. Is there any solution for the external voltage issue OR the scan tool connect issue?
Sorry I'm just a bit frustrated STILL being in the transition phase between 7 and 8 which complicates things every time an issue comes up.
