As far as J2534 module programming goes from the Maxi Sys Pro Tablet , only some models of BMW and Mercedes during your one year update period. You should be able to uses the J2534 VCI(Maxi Flash) and use it off a windows laptop and an OE program ,with a purchased subscription off OEM's websites.
If Autel wanted more people to buy updates , they should allow Pro owners to down grade it to a regular MS908 at the current 905 -906 update price, because the regular and Pro software has virtually no difference in capability other than server access to BMW and Mercedes Benz programming files, and when updating for added newer car coverage, the functionality of the older software seems to be decreasing as Autel likely has to comply to on going court ordered changes to it's software and finding it's a lot harder and expensive to r engineer unique software than to just hack and copy.
