Chris - are you looking for a SAW setup or for Oval racing?

Ron - upload your log file and I can take a look.
Let me know if you are looking for something specific or general info.

Excellent tutorial on the data log. Keep in mind this is a video for car speed runners but 90% is still applicable.

this is what I got when I hit save , it's not the graph

Yes, that is a comma delimited file for use in Excel or the castle data viewer.
You need to download the Castle Link software. When installed, you get an additional program called Castle Link Graph view.
This only works in Windows, not on Mac.

Open Castle Link and go to 'Graph Viewer (Castle1.jpg)
In the Graph viewer, select Load data (Castle2.jpg)
Select that file you uploaded, and the view will change to Castle3.jpg

If you're in the graph view, just draw a box around the area of interest and that is how you zoom in.

I do not recommend loading this data in excel or other spreadsheets, just a lot to deal with.

That Ripple voltage is way too high.
Better put some extra caps on that ESC,

Not disagreeing with the ripple, but there are all kinds of issues in this log.

Throttle command is not getting to the ESC with partial total blackout.
ESC is not calibrated correctly, max power is barely at 70%. I bet that is because of the bad throttle command.
All that alone can cause crazy ripple voltages.

I would make one change at a time, fix the y-cable issue, recalibrate and do a clean run to look at the log again.

Thanks, but I am not the one with the problem. I just keep a bunch of these files on my hard drive for performance comparisons.
