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.
What version of Hotwire are you using? Do check plug in ONLY the Hotwire, launch the software, hit the "help" button.
Checked the hotwire, it's 10.2.2. Next steps? Also, now the 2 cars that I tried to set at 0.1s resolution aren't recording any data anymore, just empty every time I try to download the data?
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?
You're looking for a steep peak not really a broad "curve" here. I go over this in the Tekin Clinic Video: https://www.youtube.com/watch?v=69d7...ature=youtu.be
I watched the video. I had watched it when it first came out, and like I said, that was my understanding of what you're targeting too, thanks for the confirmation. Follow up, do you look for the same flattening in Mod? I was just datalogging my Mod car, it's a 5.5t, and on the track dropping 5 teeth raised my rpm from 28,000 tp 50,000 on the straight, but it's not quite rolling over yet. Just out of curiosity, I picked the car up and pulled full throttle for a couple seconds, it recorded 80,000rpm!
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?
There is no way at this time. However we are working on an option to allow multiple runs to be laid over each other for viewing.
Ok, thanks, that's why nothing turned up on a search. I guess my followup would be, do you think an RSX with 0.1sec resolution data logging combined with a Fantom load would make a useful dyno? It wouldn't give you absolute values, but if all I'm interested in is which of my 17.5 motors is stronger, it would give you comparative curves of your different motors (would be really helpful in this if you could overlay 5 or more curves). If it's a lost cause, then I won't wait, and I'll start to look for other options.
Thanks in advance for the help!
