I spent some time today working in DashWare and created some custom gauges based on the M3. DashWare is a nifty program that lets you combine telemetry data recorded on Harry's Lap Timer Pro with external video, GoPro in my case.
It took me quite a while to figure out how to set up all the inputs and photoshop out the needle from the speedo, etc. I see now that I left some rough edges along the top of the gauge, and I messed up my G force plot. I'll go back and polish it up later, but I'm pretty happy with this first attempt. I now have a good understanding of how to make it all work.
I can literally make fully customized, functioning gauges for overlay for any car. Pretty cool.
Check it out and let me know what you think...any suggestions of a better layout, etc?
Edit: By the way, I couldn't add the RPMs because I don't have OBD2 access in Harry's Lap Timer. Also, I used the Autocross function in Harry's to create a quick "track" around my neighborhood.
