Nyet: you software is really great. It reminds me my kart Mycron4, which I can log and plot a lot of things in kart racing... Keep the good work.
One question: based on my gear ratios and my wheel size, how can I calc my RPM_per_mph? In mycron software we only need to input gear ratio and inflated tires diammeter. I have no idea how to calc it to input on your software
the best way is to use gps in 3rd at a fixed rpm... hold 3k rpm or something and divide 3000 by mph.
PLEASE feel free to email me (or post) bug reports and/or feature requests.
