I was hoping someone can answer this question for me. I have a sample of the log data (i.e., current, voltage, speed, etc) and imported in RaceRender. However, I couldn't get the gauges to register the data past the 2nd line. Then I read the notes (on this page http://racerender.com/RR2/docs/HowTo-Datalogger.html) and it says it needs the "Time" or "GPS Time" in the file. Once I added this column with some dummy data, it worked. So my question is, how did you guys get this "Time" data. Did you manually put it there? And if you select 5hz like Justin said, is that every 5 seconds?
