Hey guys,
Go to this site to download race chrono:
RaceChrono
You can log things like...
60ft et and speed
1/8th mile et and speed
1/4 mile et and speed
0-100kph time
80-120kph time
0-1000mtr time and speed
But you can also log lap times & even create your own track.
All of this is obviously done in real time
Don't think this is a repost, but apologies if it is.
