Now that I see that pic, thats what kind of plug is on the programming cable on my WB guage kit I just bought.

Yup, that's a serial plug.

They were all the rage before USB ports. USB is Universal Serial Ports.

here is something interesting I noticed. when logging my buddies truck I had to switch to the $0D adx and nothing jumped or spiked. when I switched back to $E6 adx the spikes went back to only happening once in a while and I was able to start getting good logs again. I wonder if all you have to do is reload the adx file once in a while.

Maybe? I don't know what the issue is, seems it's forever changing. Read the Seperator test bug in TunerPro section. Sometimes that fails on both open instance of TunerPro and loading a new/differant adx cures it. So you may be on to something here.

The file that started this thread I had used several times on my car with no issues. Once he posted it had a glitch I went out and tested on my car and sure enough it had a glitch again? Connect got jumpy data, disconnect and reconnect and data was solid? Why? I had used it several times over a couple weeks, always had solid connection each time?

Some seem to need a pause, some seem to need an extra byte in reply, some say Import of ads to tunerPro V5 does not account for reply checksum. Some are just same ECM and mask ID but ALDL file for cars are different? In the end I seem to be able to make them all work, but never found a definitive cause.
