Just to follow-up to my prior inquiry, I found a work-around to get data from the Mustang dyno/software and create data plots.
Originally, I was pulling the raw data .TRB files off the dyno computer hard drive, which you are supposed to be able to open in the PowerDyne demo software or the Mustang Graph Viewer, but this effort was futile. I contacted Mustang directly, but their customer support is worthless, so I had to figure things out on my own.
Onto the solution. Very simple, actually. When you are viewing the horsepower/torque curves on the dyno computer:
1) Load the curves you wish to export on the graph viewer. You can load up to 3 at a time
2) Make sure HP/TQ are plotted vs RPM on the x-axis (horizontal)
3) Make sure the both x and y axis scales are set so you can see all the data on the plot
4) Go to File > Export All by X-Axis Steps
5) "Enter X-Axis Step Size" in the pop-up box. Default is 100, you will want a smaller step size for improved resolution. I used 10, which exports data every 10 RPM for the entire RPM range displayed on your graph
6) A windows save box will pop up and allow you to save a txt/csv file to the hard drive or a jump drive.
If you need to export more than 3 runs, repeat steps 1-6 until you have saved all your data. I was able to import the csv files into Excel to manipulate everything. It's a much more powerful tool to graph your results anyways.
