In looking at your log you are logging WAY WAY too many PIDs. Look at the help file to see how the number of PIDs defined in the table affect your frame rate. You need to create different configs to do different things. One for open loop tuning, another for fuel trim tuning, another for idle, another for tranny tuning. Each one should only have the PIDs necessary to do whatever it is you're tuning at the time.
Look for threads by me with "towel" in the subject for a gen 4 idle tuning procedure (and config).
