Hey man, first of all, congratulations for your application, it's really great!
But i would like to suggest three improvements:
- On fuel economy, to have the option to display km per liter (Km/L), that's how we calculate fuel economy here in Brazil (and i guess in more places also ).
- On acceleration, to have the option to display km/h per second (km/h . s), since we are not used to see speed in m/s, so you could choose between kmh per second and mph per second, 1 m/s is equivalent to:
= 3.6 km·h−1 (exactly)
≈ 2.2369 miles per hour (approximately)The intention of this is to provide a more sensible acceleration, since the user will know that he is gaining/loosing 'x' kmh/mph each second, and this is very easy to implement .
- The hability to choose what you want to display on the main screen, for example my car don't provide the air temp sensor, so it's always zero, i would like to switch for another sensor.
Well, that's it, i hope ideas help to improve your application! and congratulations once again!
