LiveLink 2.1 still has bugs in it. I was not able to do any analog inputs for my G8. G8 doesn't have a wide band designed in, so I have to take the Innovate Analog Output and plug into SCT 3 Tuner. It worked in LL 6.5 & the older LiveLink, but am working with SCT to make the analog input work with the GM 3400 SCT 3.
With the last 6.5 update, it would often freeze up, and wouldn't re-start when I had already had it running, forcing me to go thru many screens to get it working. Eliminated track usage, period. Less issues with Ford version.
