I have flashed GMs, Fords, Chryslers, and a Volvo all with the manufacturers websites. I'm wondering what else everyone has tried and been successful and what hasn't worked? Also I have read that some people are able to flash GM vehicles with the Maxisys itself without buying a subscription to acdelcotds.com I have never been able to get it to work am I doing something wrong? I always comes up with a message that says "please use the USB cable to connect MaxiflashPro to MaxiSYS" and "make sure MaxiSYS is Connected to the internet before connection."

 I have tried multiple different vehicles and different years the furthest I can get is it will say vin not supported we will update the server in 24 hours please wait. It works great using the GM website but it would be nice to not have to buy a subscription every time. Has anyone ever done a Volkswagen?

 Here are a few that I tried:
