hey guys i have been hearing some good reviews on this unit. i went ahead and bought one, it works ok but i cant access individual pids, like abs, srs, etc. it will try and connect but then says connection error. do i have to mess with communication settings on my com ports? do i have something wrong?

 

Is it an acutal hds and mvci or a knock off, if its an acutual hds and mvci then you have something going wrong with your connection.
