ah thanks a lot, that might be a good approach as well. I found your "hacked together attempt" quite workable and came up with a simple python script yesterday for recording the raw udp stream, and later another one for splitting it into segments (= restarts; I was doing experiments around the first few corners), and then visualizing several such segments aligned with each other for comparisons. It's amazing what information just a speed/rpm readout can tell one. I totally get though, if that seems like blowing up the scope of your tool, and I'll have a look at the ACC-approach. Thanks for pointing me in the right direction!
