I seem to have come across a bug 8(
I updated my rsx to 255, and set it up with my windows pc, I think went to the track and made some changes with the android app, one thing I noticed was the boost only went to 20 but on the pc it went further.
came home to look at the data logs and when I plugged in my rsx to the pc I got a message, about the version of firmware on the rsx was not compatible and I had to re flash the esc.
