I think the Bi directional capabilities in GM mirror the OE tools pretty damn close. I might be wearing a Tin Foil Hat as a Conspiracy Theorist, but the Bread and Butter of R&D of OE makers like GM recouping the incurred costs and turning a profit from their software comes through subscriptions sold to aftermarket to access the programming files, not from getting farmed out for pennies on the dollar from a server of an aftermarket scanner company. I think GM drew a line , Ford filed suit because they felt some line of theirs was crossed, and I think some other manufacturers are considering their options whether or not to chalk it up as cost of doing business in China because they all build cars and components in China. I'm guessing a scenario where GM detected some software security breach (or IPs where an extraordinary amount of Data Mining going on and intentionally fed Bogus or corrupted data into what they considered to be security holes. The Software Engineers detected bogus stuff , set off alarms and pulled it all till what's messed up gets straightened out.LMFAO
I was wondering if the J2534 programmer presently only works from the Android based MS908P from files downloaded directly from Autel, or will it also work correctly from a Windows laptop from files downloaded directly from an OE site with a paid subscription?
