Okay, mini break through (for me at least). I have been manually editing my CSV data logs and viewing them in excel. It is tedious.
I found I can do some very minor tweaking to the CSV file and then import it into megalogview HD. It pumps out very nice graphs with minimum pre processing effort. The trial version is limited to 2500 lines of data for analysis but it still shows all the data in the graphics window.
Attached is a screenshot of a short drive. You can see the upshifts 1, 2, 3, 4 clearly.
ps I hope I'm not in trouble for bring a megasquirt tool to our party
