In Part I of this series, I talked about what J2534 was and a bit about how it works. I would like to use this followup article to lower the fear factor and tell you what to expect when setting up a computer to run a J2534-supported software program. One of the industry gurus I spoke with for the last article, Mark Zachos, chair of SAE J3138 committee and president of DG Technologies, was kind enough to talk to me about some of the most common questions and concerns their support folks field with the VSI-2534 interface kit.
