Am relatively new, will welcome ideas and professional advice as regards the subject matter. For Asian, European and American cars. Programming and diagnosis equipment or combination of 2 or 3 equipment from a professional point of view.
keep in mind that whatever j2534 tool you get, you will have to purchase manufacturer subscriptions as well. check out this link: www.obd2.com/support/reprog/OEMJ2534.html Also the j2534 tool will likely not support diagnostic but only reprogramming. Something like the Launch pad ii or Autel ms 908 has an add-on jbox or you can purchase a solo jbox to work directly through a laptop. That link has really good info, Ease is the company that does PA's emission machines.
