Charlie_M, thank you for the info. On this fellows posting, is the graphing application from Ross-tech's product or can Ross-tech plot data like this or is it just a list of data with no visuals. I would to be able plot the data in real-time and freeze it or save it. It is nice to see someone else post with data and solid information. It gets old seeing people throw out off the wall irrelevent comments and then see people run with it. I am a transmission builder and would love to get more involved in European diag and maybe the Ross-tech will give me the diag capabilities I need. Thanks again.
