Hey guys, I've searched several times and haven't found answers, so hoping someone here might know.

1. How do I change the datalog resolution to 0.1? When I’m reading a datalog, I see that it can be selected in the menu. So I selected 0.1, closed the datalog window. Hit Apply Settings in the Hotwire window. When I do a run and then look at the new datalog, it’s still showing 0.2 in the resolution drop down menu.

2. For gearing, should I be targeting that the RPM’s are just flattening out at the end of the straight? I have also heard that I should be hitting peak RPM about halfway down the straight? That wouldn’t seem right to me compared to an internal combustion engine, where you’d target to hit redline at the end of the straight, but maybe electrical motors are different?

3. I have bought a Fantom dyno & extra RSX, and had the idea to use the RSX to datalog the dyno runs. The idea is to hook the motor up on the dyno, just using the Fantom as a physical load, but using the RSX and the datalogs as the only dyno recordings. I don’t care about absolute torque & HP numbers, just about the relative difference between my own motors. So I would want to export the data log files and then import the numbers into excel so I could overlay the curves from the different motors. I see the .tek datalog files are hexadecimal, is there a way to convert those back to the numeric values so that I can graph them in excel? Is my approach even possible with 0.1sec resolution?

Thanks in advance for the help!
