So far, only issue seems to be that the RTT drop down box (SCANNER) has no way of being maximized, which means it is worthless for that function. I'd assume it's just a bug.

Updating to the 4.0 did NOT help my intermittent "High Speed Mode" reflash issue. It still SOMETIMES flashes quick (31 seconds), and mostly does not flash quick (1 minute, 22 seconds average)

I upgraded the other day on accident actually. Ive been using 3.6.26 for a long time and had no issues. Had a buddy send me over a revised tune but since he was using 4.0 I couldn't read it. I thought I was downloading the 4.0 seperatly aside from my 3.6.26 but it didn't and now I have 4.0 only. Not going to lie it scared me plugging into a friend of mines truck last night
(gen 0411) but surprisingly everything went nice and smooth. I know a ton of issues people were having are related to not having the correct firmware so if you do upgrade MAKE SURE you have the correct Microsoft firmware installed before you try to flash any vehicles. Just my experience. goodluck
