Great being able to print out the mapping. I did add "pause" to button 25 (makes it pause/back) as I couldn't figure how to get the menu up whilst driving (other than keyboard escape). Regards the accelerator/brake swapping, I noticed my brake and gas "axisIndex" (in the json file) where different so was just a matter of changing them after comparing with the original - who knows why they are different!!!
Thanks for your efforts.
